V = 16.17 +/- 0.09 on April 12.
Telescope 0.5 m f/6.8 Corrected Dall-Kirkham with f/4.5 Focal Reducer
Camera FLI PL11002MNick, looks like it cannot find the magnitudes of comparison stars in the ensemble. I’ve just went all the way – opening a 16-bit FITS file (ugc7513_000.fits), doing Iteratively Subtracted PSF Photometry, then set catalog to Gaia DR2, CCD Filter to G manually, ran Get Comparison Stars, then Find Regression Model and finally was able to get differential magnitudes by mouse-clicking on the sources. Try removing the old .phot file and executing the same steps. I’m going out of town for a couple of days but hopefully will be able to assist with delays.

V = 15.778 ± 0.07 with slightly better data from tonight.

Measured it at V = 14.665 ± 0.04.

Nick, here is 0.13 with Gaia DR2 and non-linear image stretching for better views:

For the time being just ignore those. I’ll clean things up soon. As long as the program itself works, it shouldn’t impact on anything.
Nick, great! Please don’t hesitate to submit feature requests. I am trying to feel where to take this next. Perhaps, command-line processing… Definitely need a way to save all the settings.
Nick, Michael, thank you very much. This one should open Nick’s FITS fine:

Very strange. If you could send me the FITS to maxim.usatov at bcsatellite.net I could take a look what’s up with it. So far it did load all FITS files fine on both of my FreeBSD and Windows computers coming from different remote telescopes.
Michael,
Glad it works. Windows is doing these constant changes – head goes round. Any feedback is much appreciated. Let me know if you’ll have any questions. Version 0.12 is already in the making with the ability to subtract VSX stars from the ensemble and report VSX sources nearby.

I have it at V = 15.77 ± 0.05, although correct PSF fit is a little difficult.
Observatory: New Mexico Skies at Mayhill, New Mexico – MPC H06
Telescope: 0.50-m f/6.8 reflector + CCD + f/4.5 focal reducer
CCD: FLI ProLine PL11002M CCD cameraFilter is Astrodon V.
I can recommend SkyTools in addition to StarAlt mentioned above:
