Re: RGB brightness cataloque

Hello, do you refer to the smaller catalog of 1346 stars or the bigger one with 15 millions stars ? At the moment other catalogs cannot be added to the Star Atlas, but these two catalogs could be accessed by an image processing plugin, for example to create a synthetic image, a reference to calibrat...

Re: Time stamp for recorded airmass

Hello, the airmass is calculated at mid-exposure.
Instead, DATE-OBS is always the start of exposure in the FITS standard, and mid-exposure is a calculated field, as: DATE-OBS + EXPOSURE/2.

Re: Vanderbei Deconvolution for coma and field curvature.

That's interesting. Yes, that plug-in is single-threaded. It looks like most of the blurring is caused by image deformations from different wavelengths, not PSF. Maybe after having separated the image into R-G-B channel the new alignment with distortions could attenuate the problem (align R to G, th...

Re: DDP star bloat

Hi, it's not easy to reply without seeing the actual image. By the way, you could use the StarNet plugin to apply DDP only on the nebula and not on the stars: 1) Duplicate the image, let's call it "B". 2) Apply your DDP on image "A". 3) Apply a DDP with low gamma and mid white point to image "B" (so...

Re: Moving Mask by Pixel in any direction

Hi, just select the last tool in the Mask window, then click the arrow buttons: If you zoom-in the image, it will be precise to move the mask also with the mouse.
Greetings, Fabio.

Re: AllCometEls.txt vs CometEls.txt

It must be happened in the last 3-4 days. That would cause trouble to a lot of software.
For the moment the only solution is to rename the file after the download.
Thanks, Fabio.

Re: Blink Full Screen negative mode

Hi Andrew, OK, it will be added to SP4 next week. Meanwhile consider the option "Alternate colors" to blink the images with slightly different colors, see the following animation:

Re: Stacking 10in F7 and F5 images

That's interesting. Using an improved algorithm it was possible to obtain the following result: N891sum2.jpg It's still not perfect (the "double stars" in the corners now look like "coma"). The correction is now included in SP4, if you like to receive the prerelease please write me by PM ore email. ...

Re: Stacking 10in F7 and F5 images

It looks like the distortions from F5 and from F7 are too different, even for that option. May you post the two separate images?

Updated ASCOM plugin v2.72

Hello, an updated plugin for ASCOM cameras is available at: https://www.msb-astroart.com/down_en.htm#cameracontrol which fixes two possible problems: 1) Setting an invalid temperature could block the plugin. 2) The ASCOM Chooser may not show up. If these two errors do not affect your camera, there's...

Re: 64bit Camera plugin - it works!

No, it does not update camera plugins, use those two files to change between 2.60 and 2.70, but to uninstall 2.70 you also need to delete those two files "_64ASCOM.dll". Looking at other forums it seems that a 64 bit ASCOM driver for the StarShot does not exist. So the only solution is to delete tho...

Re: 64bit Camera plugin - it works!

It looks like that the StarShoot ASCOM driver is 32 bit only. with an internet search: starshoot ascom 64 bit it's possible to find the same issue on other software, for example: https://aptforum.com/phpbb/viewtopic.php?t=2395 At the Orion web site the latest ASCOM driver is version "100209", maybe ...
