Speaking of astro work...
Here is my collection of astro photos: https://www.flickr.com/photos/ellarsee/collections/72157627826423347/ You can also search my flickr feed for key words like milky way, astro, comet, meteor etc. A short form of things I’ve learned: Focusing can be a bitch. My best success has been to go into liveview, aim at the brightest star or planet, crank the LV magnification all of the way up and do my best. It also helps to take some blue masking tape and “lock the focus in”. The faster the lens the better. I don’t like shooting any slower than f/2. When doing an astro-pano that includes the horizon, have one set of frames shot close to, but above the horizon and an overlapping set that is mostly below the horizon. Occasionally I experiment with the “below the horizon” frames not be on astro tracer, but the foreground is going to be dark, it doesn’t matter to me as much if it is a bit blurry. Every time I go out and shoot, I end up doing a bunch of test frames. With ISO invarience, it’s better to get your raw frames at too low of an ISO and bring the up in post than to blow out brighter objects. Again, experiment. What I really need to learn is image stacking. For straight astro, I’ll never do as well as the hubble, or even someone with a decent scope, so I usually concentrate on astro-landscape, which means finding something pretty to put in front of the sky. I haven’t had a chance to play with the K-3 III yet. -- Larry Colen l...@red4est.com sent from ret4est -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: OnT: Grey Matter Exercise
Too easy. I have two favourite cryptic crossword clues, neither is difficult, but I like them. One that my housemaster told me when I was about 12 and he was explaining what cryptic crosswords are: Gegs (9, 4) And another which I saw on a book cover: Two girls, one on each knee (7) > On 25 Jun 2023, at 20:43, Stan Halpin wrote: > > Cormorant … > > Sent from my iPad > >> On Jun 25, 2023, at 6:17 PM, Alan C wrote: >> >> Crossword clue: >> >> Large diving bird from cold, wild moor and tarn.

I thought it did increments of 10 seconds. I inadvertently pushed the green button and lost in body timing and forgot how to get it back. So I was counting elephants. First of all, one of the challenges of astrotracer is that if the geometry of the image isn’t uniform, then you’ll get motion bluring in some parts of the image, like you seem to have gotten in the corners. The A15/3.5 isn't the best lens for this stuff. It vignettes, it has coma, and the motion blur with wides seems to be a weakness of the Astrotracer. It’s hard to tell on my screen, but it seems that you may not have quite nailed focus. What I tend to do is to find something bright at infinity, like jupiter, zoom in on live view manually focus, then ideally tape the focus ring down with blue tape. I was having a bugger of a time focusing. I couldn't see anything through the viewfinder, and the rear screen was useless because of noise. I was trying to focus on a farm light on the horizon, but even that wasn't working well. You’ve got the weird color going on in the sky, I think that’s pollution showing up close to the horizon. There was a bit of pollution, but I was having some fun with a selective colour mask.

Pentax MX Film Advance Lever
Hello all Quick question - does anyone know FOR SURE if there are any other Pentax cameras that have an identical film advance winding lever to the Pentax MX - including the method of attaching to the mech under the top plate? Thanks in advance.
