astap program Reviews

Very feature rich, very accurate, and very easy to learn. It's a must have piece of software.

ASTAP is now my go to image stacker. It is easy to use and has plenty of power. The developer Han is really helpful and sometimes posts bug fixes within hours of them being reported. I use it exclusively on the Mac.

Best Astro program

Fantastic plate solver software!

ASTAP delivers highly accurate stacking results even out of mediocre data. Of course there is a steep learning curve at the beginning - as with every high specific AIP[*] software but with some patience I learned step by step what to look for and how to use ASTAP. Basically, the user simply needs to provide light frames ("images"). Calibration data (flats, darks, flat-darks (aka "biases") should be provided by the user but can be committed when not available. * One thing could be significantly be improved, if at all possible: speed! Following the running processes (Linux "htop"), ASTAP seems to never use more than 1 processor even when 8 processors are available. On my 8 core computer, most other AIP software (eg. Siril, StarTools, ...) use as much processing power as provided by my system. I am still learning ... and this will probably never end :-) [*] AIP: Astronomical Image Processing

I'm no expert, but I found this programme easy to use, very fast and very accurate on stacking. The ability to solve and stack on solution is a bonus (that I don't use much). The ability to calibrate, stack, align and combine rgb separates (darks, bias, flats, lights and flat darks by filter) is just gobsmacking! If you use the fits field editor, you can also stack and combine narrowband and calibrate by exposure time as well as filter - excellent. Not tried mosaics yet!

I am a fan of ASTAP and a user from the very beginning. I use it in conjunction with HNSKY and CcdCiel. I have used a lot of programs but now stick to ASTAP. It is unprecedentedly good and easy to operate. The support that Han provides is excellent. An absolute must.

Fantastic application for any astro-photographers out there. Plate solving is second-to-none, stacking works a treat plus there are many other additions such as the CCD inspector. Even the FITS viewing capabilities are better than anything else out there. Also the support from Han is extremely friendly, fast and helpful.

5 stars for the solver alone, and there is more.

Great work !!
