Saturn and 5 lunar shots...[L]

Posted By Joe Ulowetz
Paul, good job! I especially like the Hadley shot; I've always liked looking at the Apollo 15 landing site. You have really good detail there!

Why no Fastar pics?

Posted By Joe Ulowetz
Good question, Mark. I only have a Celestron 5i currently, but I assumed my next scope would be Fastar compatible to get some great exposures. So I'm curious also.

Jupiter 10/16/04

Posted By Joe Ulowetz
Wes, I really like your image.

I think I took mine within a couple of hours of yours.
Nexstar 5i, 300 frames (manually selected 250 in Registax2), f/30, 1/33 sec ToUCam.

Window's photo processing

Posted By Joe Ulowetz
As an initial suggestion, I use "k3ccd tools" to capture video w/ my Toucam, and Registax 2 for processing. There is an article in the new (April) issue of Sky & Telescope on using Registax that I found helpful.

Both of the programs are freeware (thanks to their authors!)

A request for comment from the imaging Masters...

Posted By Joe Ulowetz
Gary,
I have some notes I put together on suggested accessories (like electric focuser, dew heater, etc); I did this for my a presentation at my club a couple of months ago. I'll send you an email this weekend and see if this is what you're looking for.

My goodness! Not one Jupiter, but two!

Posted By Joe Ulowetz
If I'm doing the math right, you posted these about 90 minutes after taking them ?! Talk about near-realtime images! And not too bad either. Good work.

beginners advice

Posted By Joe Ulowetz
Greg,
I've been using a ToUCam for planets for about a year, and I am also looking into something for deep sky. I considered the SAC cameras but unfortunately their software doesn't work with Windows 98 and I'd have to buy a new laptop to be able to use them. (To be specific, SAC told me the software works inconsistently on Windows 98 and uses an Active X driver no longer supported by Microsoft, so I could end up with a camera I couldn't use.)

So now I'm looking into the Atik cameras, which can work with Windows 98. The SAC electrically cooled cameras would probably do better than the air cooled Atik, but that's not an option for me.

My impression is that although a $150 webcam can take cutting edge planet photos, it appears to take a few thousand dollars for a camera (usually an SBIG) to do spectacular deep sky. I thought I'd start with a low end camera and see what I can do with it.

Help w/ technique

Posted By Joe Ulowetz
Donald,
I have a C5 and use a webcam at f/30, so if I lose the image it is a real pain re-locating it. The red dot finder isn't going to help. So I rigged up a cradle for a 8x50 finder I had and use a bungee cord to hold it to the tube of my C5. When I get my initial alignment on my target planet, I note its location in the finder. It's good enough for me to relocate my target on the CCD if necessary, even though the finder is only 8x.

Good luck.

Nexstar 8i and photography

Posted By Joe Ulowetz
I have a NexStar 5i. I've only used it with a Webcam so far, and it works fine there. I want to try deep sky next, but I'm sure I'll need an autoguider for anything significant, perhaps anything over 30 seconds (even assuming perfect polar alignment).

Does the 8i have PEC? If so, that would help. The 5i does not.
