For those following Tim and my side discussion, he emailed me the updated link to that software : http://www.newastro.co​m/book_new/camera_app.​php (external link)
It looks pretty cool.

I was just about to post the same thing this morning. It is pretty fun to play with and with the extended image set you can look up just about anything. Planetarium programs like Starry Night Pro have a similar function you can use on any part of the sky. That's what I use most of the time to plan my next astrophotography session.

Mike and Sky of the Plains, not sure which one of us should thank you but I'll offer some for the team. :D

A couple of them stand out but all are impressive.

This was shot 2 weeks ago from my observatory. It's a stack and composite of 36 5 minute exposures for the outer areas and 30 30sec. exposures for the trapezium area. I used a self modded 40D and an Orion ED80 with Feathertouch focuser. This was all riding on an Atlas EQ6 mount using EQMOD and StarryNight 6 for scope control. Autoguided with a Starshoot Autoguider.

Although it's not just M42 I thought I would post a shot I took last year. It's a mosaic of M42 and the horsehead region. I used a self modded 40D and a Astronomy Technologies AT-66ED on a Celestron CGE mount. 2 hours of exposures for each object over 3 nights.

Great work. I shot the two regions and did a mosaic taken with my FS-60 a few eeks ago. Amazing what those little refractors can do isn' it?

I can't get anywhere near the standard of other images here, but I'm quite pleased with this attempt from last night.

Set my 600mm f/5.9 scope up on the markers on my patio, hooked up the power to the mount and camera, checked the focus, fired off a couple of test shots, then left it running snapping 30s exposures at ISO1600. Came back 20 or so minutes later and there were a lot of images to scrap, and I only ended up with 12 good ones. (Weird how sometimes the tracking is fine, sometimes there are big trails.) I did try some shots with my Astronomik CLS Light Pollution Filter, and M42 looked nicer, that's for sure, but I was having to go to at least a minute, and my tracking was playing up. I didn't expect much, but when stacked with 9 darks and 9 flats I was pleasantly surprised. Could probably extract better colours if I knew how, but for now I'm happy.

I also tried a shot at the Horsehead, but failed. Took a couple of pot shots at M1 and managed to get it to appear. Also shot single exposures of the clusters in Auriga, namely M36, M37 and M38. So a productive night out. It wasn't that cold, which was good, and it was very clear.

Great shots Strgazr27!

You too Adrena1in! For only 12x30 Sec you did a great job processing them.

Nice work Tim. You captured some very nice detail in the short exposures.

MIght be periodic error that you're seeing on some shots. Out of 30 shots, how many are near perfect at 30 sec.? Is the movement appearing in many consecutive shots or sporadically?

Balance and level are crucial. If you are perfect balancing your mount at set up(should be), are you adding a slight bias(extra) weight to the EAST side of the mount when imaging? Many times this will settle things down especially if you are imaging something low in the sky. When your counter weight is very low there's not much tension being applied to the RA worm gear. That can cause stutter or backlash. The tolerance space between the gears can allow for some teetering when there's insufficient resistance weight.
