Does this combination give too small an image scale??
INDI calculates a FOV of 16.6 x 11.7 arc mins in the alignment module which should fall into the
index files range which I have installed.
However i cant get plate solving to work
I can solve @ 1280mm using a cannon 60Da and an ASI294 and I have used the ASI183 @ 390mm( hyperstar) on the C8 but i cant get it to solve on this more zoomed in configuration of using the C8 and a 0.63 focal reducer and an ASI183.
I have my guide scope and main scope pretty well aligned so i can get the scope pretty close by solving with my guide scope/cam. However to get that last bit of accuracy and to find out the field rotation i need to be able to solve through the imaging scope.
This is using astroberry btw . It has just occurred to me i havn't tried this using stellarmate...
Maybe worth a go tonight..clouds permitting.
Experimentation is tricky this time of year with the short nights..
So it turns out that the calculated FOV with the version of INDI with astroberry was caluclaing a FOV of 11'x16' for the same camera/scope combination.
The same combination using stellarmate gives a FOV of 35.4 x23.7 arc mins
Plate solving works fine with the latter FOV.
I just had a similar problem last night. When I put a reducer on, built a new scope, and chose it as primary, the solver would not solve it. Plenty of stars. Turns out the FOV was wrong. I manually entered something close and it solved, and then it filled in the proper FOV.
