CCD for Planets

Posted By Brian Maynard
I don't know the price range of the Starlight cameras. Other than that, if your primary intrest are planets, you really dont need a built in autoguider. The prices really shoot up with imagers that have built in autoguiders. If your setup can accurately track an object for 30 to 60 seconds, you can get good results for deep sky imaging by taking multiple images and stacking them without autoguiding. Others may have some suggetions but, there really isn't a "do all" imager in that price range. SBIG's ST7 with a built in autoguider and color wheel will set you back about $3200.00. You may be able to find a used one in the classified section of this site in your price range. They don't come up very often and when they do they go quickly. Good luck.

Thats very good. Nice detail

That is a very big FOV Andy. Did you have any blooming problems with those bright stars? My ST7 blooms big time on this object. Color data will be an all nighter smile

C8-SGT first light with image

Thats pretty good considering all the atmosphere your looking through.

A question for the GURUs (SAC8 tests)

Posted By Brian Maynard
Hi John.
I'm no pro but I would like to put in my 2 centssmile First, the 8 bit ccd is only going to show half the number of shades of gray that a 16 bit camera will, obviously. So stacking the images will only improve the signal/noise ratio.
I think the H-alpa and OIII filters should be in everyones arsenal for deep space imaging, but again, they only isolate specific wave lenghts of light and do nothing for the dynamic range of the CCD.
I personely haven't seen any filters for galaxies, but I have seen H-aplha images combined with the regular LRGB of galaxies that are quite stunning.
For the most part though its hard to see any big difference between 32,000 shades of gray (8 bit) and 64,000 shades (16 bit). I think that you will get just as much enjoyment from your imager as anyone else will from imagers costing much, much more. Hope this helps you some. I'm sure you'll get others that will give you some great help.
Have a great nightsmile
Brian

First Photo of Mars

Hi John,
Actually, The conduitions you are talking about are ideal for high resolution planet imaging. The warm, moist, hazey air helps stableize the atmosphere. The ground fog is even better. It looks like a focusing issue or perhaps your scopes collmination. If your collmination is of just a little bit, it will degrade your imaging potential. Of course first images are always a bit rough and your image is better than my first attempt. Check your focus and colmination and you should get some outstanding images from an 11" scope. Keep imaging and they will always get better. Have fun smile

Outstanding as usual Tan. I like the RRGB better.

M27 with 10D

Posted By Brian Maynard
Looks pretty good to me Mark. How was you able to cool the camera?

Mars with Phobos and Deimos

Posted By Brian Maynard
Very cool. I was waiting for someone to do that smile

Not Mars the Moon

Posted By Brian Maynard
Nice Wes. I seen one of your moon images a while back in Astronomy magazine or Sky and Telescope, I can't remember which one. This image is very interesting. I guess there isn't one feature on the moon that doesn't have a crater or two. Even the craters have craters smile
