Hello Bebef,

Could you indicate the resolution of your screen, the DPI settings and make some screen shots of the dialogs? This problem is new for me but I use a old 1920x1080 monitor. 4k seem standard these days, so yes maybe it is time to adapt.

ASTAP version 0.9.53 is released. Latest addition is a dark spot filter for CMOS cameras (like my ASI1600MM-Cool). Furthermore the ASTAP plate solver is integrated in CCDciel program as plate solver.

To all HNSKY users, Three new star databases are released. They are based on the Gaia DR2 release from ESA. Are you a visual observer, you could download the G16 . Astrophotographers could download the G17 and or G18 . Or you just keep the old databases. They don't contain a real star designation (n...

The Gaia DR2 star catalogue is released today. For people who are interested, it is online accessible by HNSKY 4.0.0f under the same Gaia menu option. It could be slow the coming days since a lot of gbytes are downloaded from Vizier. Most people will see no the difference. The current catalogues are...

Hello Ruedi,

In the latest version PlateSolve2 is replaced by the internal ASTAP solver. It should works the same. So ASTAP can mimic PlateSolve2.

Hello Jim, The team of Astronomy.net is flexible. Note that I just released an ASTAP version with its own internal solver. Very preliminary, but the question comes up if I should keep on supporting PlateSolve2. I could now fully mimic Platesolve2 rather then being an interface. If you have time, can...

To all, I just released version 0.9.30 of ASTAP. This version has it's own internal plate solver. I think it works well but more testing is required. It has not many settings. First you have to download the U16 star database of 419 mbytes. Just extract it in the program directory. /opt/astap Then th...

Hello Jim,

Above is maybe too complicated. You better just use the sensor_size in (micro)meter and image_size in degrees in the same formula. This will give the correct result for the original and stretched image.

Hello Jim, The calculations and keywords are as follows: focal_length[m]=pixelSize*3600*180/(PI()*pixel_astro_size*1000000) where pixel size in micrometer pixel_astro_size in arc sec So for your telescope: 0.754=5.19*3600*180/(PI()*1.42*1000000) So focal length is 0.754 meter. in SI units: focal_len...

Hello Jim,

I don't know if you use the viewer, but to assist I added the image dimensions in pixels and degrees to the status bar.
