Thanks to Jerry Foote who talked me through the process (Thanks again Jerry) I was able to shoot and assemble a couple of 9 panel mosaics of Comet Holmes tonight. Each panel measures 9' x 13'. With a 5% overlap I'm guessing that nets a field of about 25' X 35'. I tried to add them to the UA Gallery but somehow managed to delete my section... (And I'm supposed to be an administrator?) So I've planted them on my site until I can move them to U-A. Both were taken with a C-14 @ f/11, SBIG ST-10 binned 3x3 and chilled to -25°. Because the exposures were so short I did not need to guide. Each of the 9 raw images used in each mosaic were reduced with flats and darks before being woven into the final product.

Patrick, I love the exposure on the 5" version. It's now one of my random desktops :) Nice work! Dave

I was out observing the comet again last night, enjoying the view courtesy the binocular parallelogram Chuck Hards built for me with the 15x70's, and decided to give him a call and see how he was doing; see if he had seen the comet yet, find out how his scope was coming along, etc. He asked me to pass on to all of you: "Please let the list folks know that I'm thinking about them, but still up to my armpits in earning a living and raising a kid. Hopefully I'll turn my list mail back on sometime in December, when I can come up for air." __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

That's a terrific shot, Patrick. So what's the secret of assembling mosaics? I've had a terrible time with PhotoShop.

Great shot Patrick! The detail in the core is exceptional. Nicely done.

The secret? Knowing Jerry Foote. :) Jerry is the one that told me how to do it. Bottom line was learning that I need to work with the FITS files produced by the cameras. I had been trying to use JPGs made from the FITS. That does not work. Hopefully I'll have a few more to share shortly. Before the clouds moved in last night I shot 25 panel mosaics using 5", 10" and 15" exposures. Also shot a 300 panel high resolution mosaic of M-31/32/110. Distributing the whole thing will not be practical since it'll weigh in at over 200 MB (ouch!) but I'm hoping pieces of it will be interesting. 'Course it's going to take forever to process and balance each of those 300 panels and stitch them into a final product so don't expect it anytime soon. Cheers, patrick
Comet mosaics: In case anyone cares, I realized all of my Comet Holmes mosaics were flipped. I've corrected and reposted them (north is up). http://gallery.utahastronomy.com/v/patrickw M-31/32/110 Mosaic: It looks like the 300 panel mosaic I spent 2.25 hours shooting of the Andromeda galaxy the other morning did not use long enough exposures. Groan... So it's back to square one for that project. "Incoming" update: A couple of days ago I forwarded a post from the Minor Planet Mailing List highlighting the buzz there about the newly discovered asteroid that was heading our way and would soon be making a record close flyby of Earth. Well, it turns out the asteroid tracking folks were not talking to the spacecraft tracking folks. Seems at the same time MPMLers were excited about the incoming asteroid, the satellite folks were excited about an incoming European spacecraft called Rosetta that's due to make a close pass by Earth en route to a comet. Turns out the asteroid (which had even been given an official minor planet designation by the MPC) was actually the spacecraft. LOL! patrick
