Correct Exposure

Hi Robin, Your tutorial"Picking the correct exposure for Deep Sky" is very interesting and informative. Essentially as you explain, the correct exposure is primarily dependent on read noise and sky background brightness. I wonder if you could answer a couple of questions? 1-Obviously when one sets t...

Focuser controls gray out

Hi, Sometimes when focusing using the focus tool, the two "In" and "Out" buttons become grayed out and inoperative as shown. SharpCapFocuserIssue.PNG The step size controls still work, so it's not like the focus window is crashed. I think this may occur when I press the "In" or "Out" buttons too qui...

I'm not using any of the cameras that are not implemented in the 64 bit version. Odd that no one el...

Re: Another Offset Question

Hi Dave and Robin, I've been running a few more experiments which may or may not be of interest. I appreciate the time you both have given my questions and I've certainly satisfied my curiosity about why you need to increase offset with gain , at least assuming you always want the least offset possi...

To progress this, as requested previously above, please make available somewhere a bias frame which has the histogram banging into the LHS in FITS Liberator and the corresponding SharpCap histogram CSV file (posted ~Dec 23).

Dave
Ok thanks. I'll do that soon.
