Re: SharpCap 3.2 crashes on startup

Hi Robin, I upgraded to version 3.2.5936.0, but the problem is still there. However, when I install the new 64 bit version 3.2.5936.0-64bit, the problem disappears, so that seems to be the fix for me. 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,
That'a a really good explanation by someone with impeccable credentials, and your right, that Horsehead is stunning.
Cheers

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.

Re: Another Offset Question

Steve Well, as it happens, I do have that option checked since It needs to be unchecked unless you are doing astrometry. Have a look at this thread https://forums.sharpcap.co.uk/viewtopic.php?t=1108 where I describe the use of the batch processing facility in ImageJ to resolve (thanks to @oopfan fo...

Re: Another Offset Question

Thanks Robin, That's a great explanation - I think I really get it now. Being a bit of a geek, I really feel I need to understand the underlying mechanism. To that end, I've been running a few experiments here. These are all graphs made from the histogram SharpCap outputs. All are 1ms darks. The fir...

Re: Another Offset Question

Thanks for that Robin - you did far more than you should have given your current medical condition. Steve - in File > SharpCap Settings > General Tab , what is the state of Save 10/12/14 bit images in FITS files without stretching to 16-bit ? If this is checked, then it needs unchecking for normal ...

Re: Anomaly with RestartPreview command

Hi Steve, for now I'd suggest looking for a workaround to find an alternative way of achieving your goal without using the restart preview option. For instance you might try doubling the exposure value (which should cause the current frame to be dropped in a new frame to be started) and then settin...
