Following Andy’s advice i now have ANSVR indexes in the right place and it solved perfectly two nights ago - ‘centre here’ worked fine and i imaged for two hours. However last night I could not get solves over a two hour period of trying with either elbrus or ANSVR.
Just dealing with ANSVR 1st - here’s the inconsistent bit.
I took a 10 sec exposure with lum filter set, right click, plate solve, blind solve and watched the ansvr log - provided a solution with 100% confidence RA/ Dec/ angle as usual.
Now to start my sequence, i used ‘centre here’ putting in the RA, Dec and angle values from the previous blind solve. Elbrus fails to solve (unfortunately that’s 90% of cases for me), but ansvr fails to solve too. There has been no significant telescope movement - we are talking just a few seconds between the solves. I kept trying this over two hours or so then gave up.
With regard to elbrus, it consistently fails to solve. A few ansvr solves indicate the camera angle to be 49, 50 and 52 deg and i have tried putting in those values.
One question you would wish to ask is what does the ansvr log say when the ansvr solve fails and the answer is it runs through all the 4205 indexes I have in place without finding a solution. Ansvr found 70 sources in the image.
Any ideas for things to try for ANSVR or Elbrus would be greatly appreciated.
I have saved a few images so I can try to solve from the saved files.
Things I have tried - move the scope by say 10 to 20 degrees to a new area of sky / take longer exposures e.g. vary between 10 and 20 seconds - result is the same.
