Thanks Donald, I’ve heard of ASCOM and FocusMax. Are they PC/Windows only or do they also run on Linux? Rick

I’m debating whether I should look at one star, using FWHM or Half Flux Diameter or a similar measure, or whether there is a way to have the software look at a larger subset of the whole image. If I

If you make your focuser software interface ASCOM compliant then you could use an autofocus software i.e. FocusMax http://www.focusmax.org/ http://www.focusmax.org/ to do autofocusing.

Rick, Maybe you could look for spatial frequencies, e.g. do a spatial Fourier transform and find a spatial frequency peak that corresponds to stars. That would be pretty processor intensive. JPEG

A while ago I got a HyperStar for my C14, which converts it to f/2 using the primary mirror and some optics. It replaces the secondary mirror. I use it with my Nikon D600 SLR with great results. I

Inspiring to see what a C14 is capable of. Rick

Not sure if the C14_Edge is the same as the old C14 that used a sliding tube moving mirror focuser with a single lead screw on one lobe of a three lobed bracket for focus position. It appears that the

Thanks for the feed back. Very interesting :-) Christian

"wondering if you had tries the new ASI224 camera ?" I used one last night for the 1st time. It really looks like read noise is <1e- and it approaches the EMCCD/ICCD experience. The notorious CMOS

Wonderful resolution Stan ! I was wondering if you had tries the new ASI224 camera ? It is doing wonder for Uranus and Neptune imaging. The read noise of the IMX224 sensor is only 1 e-, which is

fantastic! Obviously that is a good site. Do you have any tips for C-14 hi-res? (e.g. cooling) Stan
