Hi Errol, I think your analysis is correct - you are getting hot pixels in the dark frame that are not present in the light frame, and are therefore over-correcting. It may be happening in the M81 image too, but the brighter background (no filter) may make the incorrect subtraction far less obvious ...

Hi Stephan, it's not something that I have built into SharpCap myself, but the tools to image an eclipse are all there, and some people used the SharpCap sequencing tool to generate automated image sequences to capture the recent eclipse (mostly) successfully. See this thread here on the forums http...

Hi, from the log, I can see an error at 02:35:22 where an autofocus scan is about to begin but SharpCap finds that the focuser ASCOM driver is not in the connected state when trying to begin the scan. The previous mention of the focuser at 02:29:39 shows that it was connected at that point. There ar...

Hi Julian, OK, thanks for the clarification. The move buttons in SharpCap should not turn off tracking, but certainly the evidence of your guiding graph and other factors does make it look like tracking has been disabled and therefore PHD cannot guide. I have personally stopped using EQMOD and am no...

Hi, I don't see why not... It might be quite small as you will get a fairly widefield view of about 2 by 1.5 degrees (see https://astronomy.tools/calculators/field_of_view/). I presume that the blocking filter in the diagonal is the only filter in the LS60THa, meaning it is a normal telescope with t...

Hi,

yes, a feature like that is certainly on the 'would like to add' list, but as you point out it's not really as simple as it sounds (and that's even before you start thinking about having multiple channels live stack data and merging them and so on...)

cheers,

Robin

Hi Prasad, I have a very old (pre-production sample) ASI174MC that sometimes does things like that. On other days it behaves itself and gives normal pictures. In the case of my ASI174 I think it is a problem with the camera itself (not sure if hardware or software on the camera). Your problem could ...

Thanks for the suggestion - like that one

cheers,

Robin

Hi Mike, if it happens again, you can check the log and look for entries like Warning 19:38:18.227459 #30 Fetching still frame from ZWO camera failed with ExpFailed, exposure is 120000, timeout is 146000 in bool SharpCap.Cameras.ASI.ASICameraProxy.GetFrameData(int timeout, BufferFrame frame, Cancell...

Hi Chris, what is going on there is that SharpCap monitors the mount location in the background every second or so. When CPWI dies, that starts failing, and after 10 failures in a row, SharpCap gives up trying. Reconnecting the mount in SharpCap will get the monitoring running again, but otherwise i...
