Re: QHY 247 offset problem
>In live mode, the camera runs continuously and is always capturing frames to display. OK, I thought I understood how that worked, but apparently not. I *was* in LIVE mode, but saw that the output was not being stored until I started the Capture function, so I assumed the counter would start over wh...

Re: QHY 247 offset problem
Sorry - overactive keyboard! Let me try again: ok, I guess I understand the typing issue (could I also hit ENTER to make sure the value is active?), but the issue regarding when the change takes effect is confusing. In every case, I took a single exposure using the Start Capture function after makin...

Re: QHY 247 offset problem
I should also have mentioned - I have FITS files that illustrate this issue. They show a initial set of 1 sec exposures with two offsets that clearly show the effect of changing offset while another set of 180 sec exposures shows none even though the FITS header shows a change.

QHY 247 offset problem
I have been trying to determine the correct offset value to use with the QHY 247 and wanted to use the tools available in Sharpcap to help me. However, while collecting the data, it seems I discovered an issue with the ability of Sharpcap to control the QHY 247. Specifically: 1 - setting the offset ...

Re: Sharpcap/APT different results on darks
Nevermind! I figured it out. It was the WB settings. I set them all to 1 and now the files match.

Re: Sharpcap/APT different results on darks
Can you remind me - do the white balance values actually change the values in the image file or are they just for preview? If the former, that could explain the difference. APT does not change the WB before storing the file. Some other info: - 2200 is 'unity gain' for the 247C - Both files show max ...

Sharpcap/APT different results on darks
I just upgraded from using an Nikon D5600 to using a cooled astro-cam: QHY 247C. I am still trying to find the best settings for the camera and while doing so, found some odd functionality with SharpCap. I took some lights using APT and set the gain to 2000 and the offset to 50 (based on user recomm...

Re: Cone error adjustment
Thanks for the reply. I’ll try putting tension in the offset screws. The cone error affects my ability to get a good PA since it throws off the center axis Calc. It also can affect guiding since the PA accuracy changes with mount position and changes the DEC tracking. Plus, I also use my setup for v...
