Around half an hour later I stepped outside again; by that time  the
eclipse was total. The moon was still clearly visible, but yellowish.

I didn't wait up for the next half hor, so I have no idea how red the
moon ended up getting.

Super Moon because it's close to perigee (appears about 7% larger).

Blue Moon because it's the second full moon in the month of January.
Blood Moon because it's going to be a total lunar eclipse.

It's a fairly rare thing for all three to occur during the same full
moon. The last time one was visible from North America was 150 years
ago.

I think we're supposed to be able to see the beginning of the eclipse
from here on the east coast (of North America).

Lunar eclipses happen a couple times a year, and are visible from about
half the planet.  Are you sure the next one isn't until 2037?





I'm guessing he means the next time a lunar eclipse will occur during a 
"Blue Moon" that is also a "Supermoon".


The last time that combination occurred when the eclipse was visible

According to my local news broadcast (usually fairly reliable)
the next triple-hit will be in 2028, with another one coming in 2037.

But maybe the 2028 one won't be visible from Australia.

Mark, for you, with the sunrise at 6:59am, it was probably bad.
But in Detroit, which is considerably west from you,  the sunrise was at 7:47am.
So, I'd say the partial eclipse (in "umbra") was probably still visible for 
Ken. (Ken, how was it?)


In our neck of the woods, we had a very tight schedule:
   Moon's
 Azimuth   Altitude
  h  moo
Moon enters umbra  2018 Jan 31  05:48.1   279.5 17.5
Moon enters totality   2018 Jan 31  06:51.4   286.5  4.8
Moonset2018 Jan 31  07:19 289.8 
Sunrise: 7:17am


The totality was starting when the moon was rather low, and would be 
obscured by the houses nearby.
So, last night I thought of the observation point that is on the
"hill" (it is very flat here, so, it is hard to find a real hill),
and on the eastern side of the major highway (which doesn't go "high" in 
this area).
So, there was a clear view to the moon as the totality was starting.

The timing was perfect: we didn't have to wake up to early, just 10 
minutes earlier than usually. We left from our house some 15 minutes prior
to the time we usually leave for the school bus. We saw the onset of the 
totality, and then drove to the school.

It was a very good timing for us. The sky was a bit bright because of the 
approaching sunrise, but overall, everything reasonably visible.
No need for early rising and no school classes missed.

Cheers,

Igor

Re: HELP! Advice on Lunar Eclipse Photography [traveling-with-tripod question]

2018-01-31 Thread Stanley Halpin
Dan, you say
> I used to bring a tripod with me, but with the tighter baggage regulations,
> I gave it up a few years back,

Not sure what baggage regulations you refer to.
I used to remove the head from the legs, put my tripod inside my large 
suitcase. Larger suitcase than I needed, but anything for the tripod…
Every single time, that suitcase was spotted and opened by TSA. And they often 
don’t do an acceptably neat repacking job.

Someone on this list, one of the other relatively frequent travelers (Mark? 
Ken? Paul?) said “not to worry, just carry it with you.” So, with some 
trepidation, I did. And have continued to do. My Lowe camera backpack has 
straps designed to hold a tripod. Works well.

My usual first flight from our small regional airport is on a CRJ-200 50 seater 
commuter jet. My camera backpack will not fit in the overhead. Surprisingly it 
does fit under the seat in front of me. So, once aboard, the tripod comes off 
the pack and into the overhead, the backpack goes under the seat, and off we go!

I do take the ball head off the tripod to reduce the weight and bulk of the 
tripod; the head goes into the backpack. The backpack often gets a 2nd or 3rd 
look from the x-ray guy, but I can’t remember the last time anyone asked me to 
open the pack to inspect my gear.

Nope - last night.

I happened to wake up at 4:25, so I stepped outside to take a look.

Around half an hour later I stepped outside again; by that time  the
eclipse was total. The moon was still clearly visible, but yellowish.

I didn't wait up for the next half hor, so I have no idea how red the
moon ended up getting.

Super Moon because it's close to perigee (appears about 7% larger).

Blue Moon because it's the second full moon in the month of January.
Blood Moon because it's going to be a total lunar eclipse.

It's a fairly rare thing for all three to occur during the same full
moon. The last time one was visible from North America was 150 years
ago.

I think we're supposed to be able to see the beginning of the eclipse
from here on the east coast (of North America).

Re: HELP! Advice on Lunar Eclipse Photography

2018-01-31 Thread Igor PDML-StR



Mark, for you, with the sunrise at 6:59am, it was probably bad.
But in Detroit, which is considerably west from you,  the sunrise was at 
7:47am.

So, I'd say the partial eclipse (in "umbra") was probably still visible
for Ken. (Ken, how was it?)


In our neck of the woods, we had a very tight schedule:
  Moon's
Azimuth   Altitude
 h  moo
Moon enters umbra  2018 Jan 31  05:48.1   279.5 17.5
Moon enters totality   2018 Jan 31  06:51.4   286.5  4.8
Moonset2018 Jan 31  07:19 289.8 
Sunrise: 7:17am


The totality was starting when the moon was rather low, and would be 
obscured by the houses nearby.

So, last night I thought of the observation point that is on the
"hill" (it is very flat here, so, it is hard to find a real hill),
and on the eastern side of the major highway (which doesn't go "high" in 
this area).

So, there was a clear view to the moon as the totality was starting.

The timing was perfect: we didn't have to wake up to early, just 10 
minutes earlier than usually. We left from our house some 15 minutes prior
to the time we usually leave for the school bus. We saw the onset of the 
totality, and then drove to the school.


It was a very good timing for us. The sky was a bit bright because of the 
approaching sunrise, but overall, everything reasonably visible.

No need for early rising and no school classes missed.

Cheers,

Igor

I heard there was going to be a "Blue Moon" on Jan 31, but ignored it,
because that is not a real astronomical event.  I even heard something
about a lunar eclipse, but that didn't seen to apply to me.

So, I am here, in the middle of the Pacific, and it suddenly dawns on me
that there will be a total eclipse of the moon, right over my head, in just
36 hours, and I am totally unprepared.  Of course, the weather is still a
problem, but I would hate to miss such an opportunity.

I used to bring a tripod with me, but with the tighter baggage regulations,
I gave it up a few years back, first substituting a monopod and then one of
those 8' models that you can place on a table or wrap around a pole.  This
year I have nothing.

Had I given it some thought, I would have brought a prime lens, or even my
old 500 mm reflector lens with an adapter.

What I have now is:

GoPro
Pentax WG-3 gps
K-5 IIs

DA 1:3.5-5.6 18-135 mm ED AL [IF} DC WR
FA 1:2.8 !00 mm Macro
Tamron AF 75-300 1:4-5.6 LD Tele-Macro /1:3.9

My principal concern of course is the weather, then staying up late to see
the event.  Assuming all goes well, any suggestions as to what might afford
to best opportunity to capture the eclipse?

I've given this a bit more thought and it seems to me you go to the same 
place every time you go out to Hawaii. If that's true, might there be 
someplace out there where you could store a tripod between visits?


Alternatively, you might consider shipping the tripod to where-ever you 
are going to stay and have them hold it until you arrive; then shipping 
it back just before you leave for home.

I have already though about the bean bag approach, and even picked up some

Years ago I framed the full moon between two palm trees, and I might try
that again.

Going up the mountain to the 10,000 foot level would probably get me above
the clouds, but it is a hell of a drive at night.

I will play around and see what develops.  :)

I hear that some folks a Mauna Kea have some awesome telephoto lenses,
maybe they'd loan you one?

You seriously are not going to even be able to get close capturing shots
of the moon itself that folks with serious gear will be able to do. My
suggestion is that you find a place that would have some really nice night
time scenery to put in front of the moon and set up some night landscape
photos with the moon in the background.  It should be in roughly the same
place about 40 minutes earlier tonight, so you could go do some
test/practice shots.

If you don't want to invest in a cheap tripod, you could make, or buy a
beanbag, and set up photos using that and the 2 second delay.

Alternatively, you could just not worry about trying to get an awesome
shot of this lunar eclipse, and enjoy the show.

The news here called it a "super blue blood moon eclipse" because it'll be a 
supermoon as well.

I can't be bothered trying to get photos of it.

Thanks, Larry and John!

I have already though about the bean bag approach, and even picked up some
dried peans to put in a bag.  I also though of using the ir remote to fire
to shutter, to avoid shutter shake.

Years ago I framed the full moon between two palm trees, and I might try
that again.

Going up the mountain to the 10,000 foot level would probably get me above
the clouds, but it is a hell of a drive at night.

I will play around and see what develops.  :)

Check out local camera stores. Maybe you can rent a tripod.

How far are you from that volcano that you sometimes post images from 
when you're in Hawaii? Can you drive up to the top to get above the weather?


Given your available equipment, I'd go with the FA 1:2.8 100 mm Macro, 
and I think the K-5 IIs has a built in intervalometer. Someone else may 
know how often you want to set it to trigger the shutter.


Try this B&H tutorial for the info you need to determine your exposure:

Hope this helps. Wish I was out there somewhere to photograph it.

What i have done in the past is to use 2 polarizing filters and cross 
polarize them. 1st one (closest to sun) must be a non circular type.

Done it this way as i am cheap and is all that i have.
Also good results can be had with a welding glass. How you mount it 
however is entirely up to you.

Mine is a Sigma 300mm F2.8 EX APO in Pentax KAF mount. It's the last of
their film lenses in that focal length, before they reformulated for
digital. It has a detachable lens hood that reverses when it's in its
case. Measuring across the outside of the lens hood it's 129mm.

The Astrozap 124mm-130mm fits snugly over the end of the lens hood. I
barely need to tighten the three thumb screws to keep it in place.

Measuring outside to outside of the front element is 115 mm, so it looks
like the hood adds 14 mm. I was able to buy from a local camera dealer
& actually verify it fit when I purchased it.

The Pentax Forums specs for the SMC Pentax-FA* 300mm F2.8 ED[IF] says it
can take 112mm screw on filters on the front and gives a Diam x Length =
123 x 247 mm. So, I'm thinking the outside of the lens hood is 123mm.

The AZ-1514 I bought might fit loosely or you might need to go with the
next size smaller - AZ-1513 117mm-124mm (4-5/8 to 4-7/8) diameter to get
a snug fit.

The page I linked before has the full line of Astrozap filters.

Funny, I've read just the opposite — of success using a DIY filter
inserted between a teleconverter and the lens it's attached to.

I'll have to do some more digging.

try to use a longer lens, like a 500 or 600mm

Re: Eclipse photography

2017-07-11 Thread Larry Colen

Just as I was heading out on my road trip B&H sent out an eclipse mailer:
https://www.bhphotovideo.com/c/solar-observing/ci/33818/N/3583558376/sba

When I was in Portland I was talking to my rocket scientist friend Phil 
about watching the eclipse, he wants to make a camera obscura to project 
the image of the sun.  It turns out that if you take a long lens 
(500mm), and place it back to back with a wide angle lens (samyang 8mm?) 
you can then focus a projected image a reasonable distance away.


We did some quick proof of concept with my bigma and my sigma 20/1.8.

Philip just ordered himself an inexpensive Celestron.  Here are his 
notes from when he was waiting for it:


From the intarwebz:

D = 0.0093P(FLtelescope/FLeyepiece)

D = image diameter, m
P = Projection distance, m
object - sun

And, if your telescope has an all metal and glass eyepiece, you can just
use that for projecting.  Even back projection, through a funnel stuck
into the objective tube, to a screen strapped on the end of it.
Reflectors can melt their secondary mirror's mounting if it's plastic.
If so, you can stop it down with a 1-2" aperture on the inlet end.
So 1 1/4" eyepieces may make the best second lens for this.  The
Celestron AStroMASTER 114 comes with 10mm and 20mm ones, so it'll
project nice images using those if they don't melt.

I then got this update from him yesterday:
Hey,

The ASStroBlaster 114 arrived.  Some things I've learned.
The tripod/mount is acceptable, though the solar image wiggles pretty 
easily, that's pretty good mag, so more solid would be better.


Its 20mm eyepiece has just enough FOV to project the sun and maybe the 
moon, but the spare on the edges is so slim that you have to constantly 
be tracking to keep up with that sucker.
A motor drive is definitely in order.  There's one for this beast, I'll 
have to track it down.


This situation should improve with wider FOV eyepieces (in theory), but 
will get worse with shorter FL ones.  The projected image size is nice 
but not as wide as I dream of for the Camera Obscura.

So, looking for very wide FOV eyepieces of 10-15mm now.

The 'scope is "A Jones-Bird Newtonian telescope ... is a mirror-lens 
(catadioptric) variation on the traditional design sold in the amateur 
telescope market. The design uses a spherical primary mirror in place of 
a parabolic one, with spherical aberrations corrected by sub-aperture 
corrector lens usually mounted inside the focusser tube or in front of 
the secondary mirror. This design reduces the size and cost of the 
telescope with a shorter overall telescope tube length (with the 
corrector extending the focal length in a "telephoto" type layout) 
combined with a less costly spherical mirror. Commercially produced 
versions of this design have been noted to be optically compromised due 
to the difficulty of producing a correctly shaped sub-aperture corrector 
in a telescope targeted at the inexpensive end of the telescope market." 
(Wikipedia)


So far, the solar image is not sharp like it clearly could be.  Have to 
see how much of that is the eyepiece.  Cool set of big sunspots today, 
though.


Projecting through the eyepiece gets you a screen that is naturally at 
90 degrees to the sunlight.  A small sized screen (1'?) and a simple 
up-sun shade could be built onto the 'scope, and you'd have a decent 
setup without much trouble.


The cover that comes with it has a hole that makes it a perfect aperture 
for not roasting plastic optics.  I may have prematurely let some of the 
smoke out of it, but it's still alive.  Turns out as the sun drifts off 
to the side, it wants to melt any black plastic mounting the secondary 
optics.  Like around that cursed corrector lens mounted at the deep end 
of the focuser tube.  Or the focuser tube itself.  Or the eyepiece. 
Motor drive!  Maybe a fan for the secondary mirror.

In any case, it seems that one critical aspect is some rough 
approximation of an equatorial mount, not to keep the image from 
blurring but to just keep it relatively centered.

I've talked to several people who photographed previous eclipses and was
told not to use the internal filters because the lens will concentrate
enough light to melt them & besides messing up the filter it can damage
the lens & the sensor. One of my sources stated he had found out the
hard way.

I got an Astrozap AZ-1514 Full Aperture Glass Solar filter that fits
over the lens hood on my 300/2.8 - "Full Aperture Glass Solar Filter
124mm-130mm (4-7/8 to 5-1/8) diameter."

https://www.astrozap.com/scripts/prodList.asp?idCategory=36

I tried it out at GFM. It worked just fine, but I'm still learning how
to aim the camera. I should measure the lens hood diameter on my
80-200/2.8 Tokina ATX-Pro and order a filter for it.

Thanks. I took a look at it & it has some information I can use even if
it is a Canon site.
