Re: Trying to quantify seeing/image-quality

I need to be able to select only the best images for stacking in a simple way. For example, I had almost 300 lights from the previous weekend on the same target, and it is a cumbersome task to open and analyse one image at the time in AstroArt. There are some images that I need to discard, mainly du...

Platesolve fails near celestial NP

The other day I was going close to the celestial north pole, and found, that Astroart couldn't platesolve. Horizontal field = 93.6 arc minutes Pixel resolution = 1.2 arcsec per pixel The fit file: https://www.dropbox.com/s/gjn5bdo21a0aay2/cannotsolve.fit?dl=0 All my settings in Astroart regardi ng s...

Trying to quantify seeing/image-quality

I am trying to quantify the seeing from fits files. Usually, I find starts in an image, look in the stars window and order decending by FWHM x, and then multiply the value with image resolution. It would be very helpfull, if Astroart could show the average FWHM for non saturated weak, but not too we...

Re: Plugin for Starnet++

I get an error message when running run_mono_starnet.bat. VCRUNTIME140_1.dll is missing It seems that an Visual Studio runtime library is missing. I have Visual Studio 2015 installed. A side note: I also tried installing the latest RT library from here: https://support.microsoft.com/en-gb/help/29770...

Re: Download speed on ASCOM vs. native drivers

I found an old post on the Danish forum astronet here: https://www.astronet.dk/forum/viewtopic.php?t=2460 Here I wrote a little about the download speed. To put it short, my ZWO 1600MM with 4,656 x 3,520 pixels at 16 BPP = 262,225,920 Bit should be able to transfer ca 20 FPS over USB 3. However, the...

Re: Download speed on ASCOM vs. native drivers

Perhaps it’s because the live view in ZWO’s software is lower quality, I don’t know.
The focus liveview probably also uses ROI.

Re: Download speed on ASCOM vs. native drivers

That’s true, data download via ASCOM is significantly slower than through native drivers, at least for Canon and ZWO, which is the only cameras I’ve been using. For deep sky photography, it doesn’t really matter for me, if every two minute exposure takes one second or 1/20 second to download. But wh...
