M57 with a webcam...

Image looks very good. The only hassle seems to be the alt-az platform; you are getting quite a bit of trailing.

CCD 4 Me???

Posted By Ron Wodaski

There are many cameras that would work. What's your budget, and what kind of imaging do you want to do (if you know that yet)? The more information you can provide about your interests, the easier it is to narrow things down.

Deep image of the Cocoon Nebula

Posted By Ron Wodaski

Here is a version of the image with boosted brightness, that I hope will reveal more of the subtle dust regions in the image.

That's pretty nifty. Thanks for posting such an original shot.

guide scope with RC ?

Posted By Ron Wodaski

This varies a lot from one RC to the next. I know folks who are having good success with this approach, no concerns at all about mirror shift during 10-20 minute exposures. Unfortunately, I know many others who are having unusually large mirror shifts and are unable to use external guide scopes.

This applies to scopes from both of the manufacturers I am familiar with, RC Optical and OGS. The best answer here is to do what others have done: If you experience excessive mirror shift, contact the manufacturer and have it taken care of. The mirror shift should meet the manufacturer's specs, and if it doesn't they should fix it under warranty.

Wow - amazing how wide this field is. Look how tiny the Crescent is! There's an amazing amount of structure here, and your image shows it very clearly.

Same goes for this one. Pretty cool to see such large objects in context.

Technical problem...

Posted By Ron Wodaski

I'm not clear on what the problem is. Are you trying to imag with the guider chip, or are you trying to do a calibration run? If you could provide a list of steps that recreates the problem, it would be easier to diagnose. It's not something I've heard of before, so I want to make sure that you're following the right steps to accomplish whatever it is you are trying to do.

Canon D60 Andromeda

Posted By Ron Wodaski

Nice work. The D60 seems to be at another level with respecty to astro imaging. Nice details, and you are certainly getting more than I expected to see from non-CCD cameras.

A comment about those vibrations. It's not uncommon to have to spend some time figuring out just what the weak link is when taking longer exposures. It could be the long lever arm that you mention; it could be something else. THe best approach is to eliminate one potential problem at a time and see what works. I recently spent over a week firming up problems with looseness in a guide scope, for example. It just took time to figure out what the source of the trouble was - it was at least 4 different things by the time I got everything stabilized.
