Hi, Using my C14 and 0.8x reducer for the first time last night, having upgraded from a C11 which used the same reducer. I have always used the ANSVR and Platesolve2 combination and it worked pretty well apart from the pesky dialog closure delay in PS2.
So I thought I’d give ASTAP a go last night, but in five attempts in three different areas of sky, ASTAP would not solve. Moreover, ANSVR as the failover would not solve. ANSVR works fine, but only if I use it first - here’s a typical sequence of events for each of the five ASTAP attempts:
Blind Solve with ANSVR - worked
Immediately followed by an ASTAP solve attempt which fails
ANSVR as failover - fails
So it looks like something odd is happening when ANSVR follows an ASTAP attempt. I appreciate n=5 so not much to go on.
As you can see with a C14 set up with a 0.8x reducer, it’s intended as a galaxy imager and the field is quite small. Can ASTAP deal with small fields?
Is there any thing I can try in ASTAP settings?
Anyone else using a small field configuration with ASTAP?
Perhaps using a different star catalogue would help? One with more stars in to compensate for the small field?
I’ve included some of last night’s data below, from an ANSVR successful solve which shows the index used, field size etc:
Field 1: solved with index index-4206-02.fits.
Field 1 solved: writing to file ./stars.solved to indicate this.
Field center: (RA,Dec) = (239.4, 29.68) deg.
Field center: (RA H:M:S, Dec D:M:S) = (15:57:44.460, +29:40:31.509).
Field size: 20.5796 x 15.5243 arcminutes
thanks for help,
