Hi guy's,, seen that old stash has been working with this and it looks pretty interesting to me given it can be added to ccdciel and be run from the raspberry pi I believe. Hoping old stash can jump in and give us his personal thoughts on this,, www.hnsky.org/astap.htm

Sorry missed this.
Pro's
Runs on number of platforms Windows,Linux,Mac ?
Very Very Fast - 2-4secs - 8 sec on PI when doing "near" platesolving.
Simple install and can be installed without an "Installer" on windows.
All std index's used to platesolve are down loaded with the software - not compat with Astronomy Index's
I have used it with my C9.25 SCT and my Canon std 35-55mm lens works on both - works well
Cons:
Complex GUI but this is due to the number of other functions it can do - Stacking ,Image analysis. If it had the simple ASPS GUI it would be near perfect.
Non "near" platesolving can be very slow IMHO. But I have no patience.
As with all Platesolving sometimes you have to adjust parameters to fit the Sky quality and Stars on view.
Can be a bit annoying odd - e.g. Platesolve with ASTAP OK then move closer to get an object more central in image - dam thing sometimes then says it cant platesolve even though I can see the bloody Star/other object is dead central. To be fair I have never taken up this point with Hans the Author who normal comes back with a solution :-)
As I said confusing GUI if it was for just Platesolving - IMO
Hope that helps!
Bottom line - I use it but dont totally rely on it.

FYI :- Update on ASTAP "blind solving" on latest version of ASTAP - attached are the screen images of ASTAP and its logs showing "near" and "blind" platesolving of M31 taken with a DSLR (Canon 100D). Results - Fastest solve was 2.2 seconds - average about 4 secs - 2.2secs was mainly using less stars but as the manual says "less stars = more prone to failure) The near test was using the actual co-ords of M31 - may sound mad but ASPS and Platesolve have ,for me, failed to platsolve when I can see the object dead centre especially with images like M31. The Blind test ,which took 106secs to solve, was using the cordinates of M81 as the starting point - this test used to timeout on the older versions of ASTAP (I set 180secs as max) so it has improved somewhat ! Test were carried out on old AMD dual core A6 8GB ram and SSD using Windows 10.
