I disagree! The poor-man approach to plate solving is uploading your picture to flickr and submit it to the astrometry.net group, it will be solved like this:
http://www.flickr.com/photos/28053...@n02/3366941517/ Hello, this is the blind astrometry solver. Your results are: (RA, Dec) center:(189.127966848, 26.5662964523) degrees (RA, Dec) center (H:M:S, D:M:S):(12:36:30.712, +26:33:58.667) Orientation:110.58 deg E of N Pixel scale:8.46 arcsec/pixel Parity:Reverse ("Left-handed") Field size :2.41 x 1.61 degrees Your field contains: NGC 4494 NGC 4562 NGC 4565 actually it would be really nice if CDC would be able to display images with AVM headers in the proper orientation and scaling on the sky as Worldwide Telescope from Microsoft does. AVM headers can be calculated from the astrometry.net info. If you use astrometry.net directly you can download the fits headers for converting them to AVM. -- Philipp Zitat von Sander Pool <[email protected]>: > > Hi Harry, > > the official way to do step 1 is to plate solve.
