Double Transit AnimationPosted By Joe Baldwin |
Very nice. I can't wait for the triple. By the way, its was faster for me to download the file by right clicking and then opening it with IE than it was to wait for it to load directly into the browser

Tom,
Very nice detail. The moons suggest your collimation is spot on.

SCT Image Quality: Maybe a little OTPosted By Joe Baldwin |
The issue of central obstruction aside, I think the most critical factors for high resolution imaging are adequate signal/noise ratio and minimizing the amount of smearing due to atmospheric turbulence. A larger aperture simply provides more photons allowing the use of faster shutter speeds and lower gains resulting in better resolution of fine datails. In a nutshell, aperture wins.

AIP4Win Features?Posted By Joe Baldwin |
Steven,
I have not used AstroArt extensively and have no experience with MaximDL/CCD but have used AIP4Win, Paint shop Pro and Adobe Photoshop. AIP4Win (the book) is, in my opinion, the best reference work available for ccd imaging. Every detail of ccd operation is covered in the context of producing the highest quality image. There is coverage for all major ccd endeavors; planetary imaging, photometry, astrometry, RGB imaging etc. The software provided performs all these basic functions at some level. However, the program is a little difficult to use for everday use. Its like the jack-of-all-trades, it does everything but it doesn't do any one thing really well. It really just gives you enough functionality to learn the techniques. For example, it has the capability to stack planetary images but it is very time consuming so I use Registax for that. It can be used for adjusting the final brightness and contrast but I find it so frustrating that I'll use Paint Shop Pro for that. In summary, buy the book for the wealth of knowledge it provides but don't count on the software much beyond the tutorials.

Monochrome JupiterPosted By Joe Baldwin |
Looks like some very fine detail lurking in there. Have you tried using any filters? I've found that using an IR blocking filter makes some improvement in contrast with monochrome sensors, especially on jupiter. By the way, are you planning to do Lrgb imaging with this camera?

Check out the bulb replacement costs. Good bulbs are from $200 to $400 and typically last 1000 to 2000 hours. If you only play movies it is not too bad but it becomes cost prohibitive ( for me) if it is used for broadcast/cable.

Is an old orange C8 suitable for ccd astrophotography ?Posted By Joe Baldwin |
Andre,
I think most Celestron fork mounts can be upgraded with a declination motor. If your drive base doesn't have a jack for the dec motor you would use a seperate hand control. The only issue then would be finding/making a custom cable to connect to the autoguider. Alternately, you could find a more recent version of the drive base, Celestar, Ultima etc. that has the dec. motor control built in. These show up in the classifieds from time to time.
