PA fails on step 2

[Prathab]

I'm using a orion SSAG with orion 50mm finderscope. This is sitting on a eq5 pro mount. Here is the view of Polaris from where the mount is sitting.

Step 1 solves every time. Step 2 does not. I have tried both sides for 90deg movement. Also tried starting at 40deg on one side for step 1, but this causes step 1 to fail.

Based on the platesolving DB will sharcap do PA in my case? How many degrees of sky under Polaris do I need to be able to see for this to work?

Thank you!

Hi,

you need to be pointing within 5° of Polaris for the plate solving routines to be able to identify the field of view correctly. The field-of-view should be an issue with your set up of an SSAG on a 50mm finder scope.

If you continue to have problems a good trick is to capture an image from the guide camera and upload it to nova.astrometry.net to get a full plate solving solution for it. Sometimes it can turn out that you are further away from the pole then you expected to be (which may be the issue).

Also, if you haven't already, check out the troubleshooting steps given here. https://www.sharpcap.co.uk/sharpcap/fea ... leshooting

The times I've had troubles with my MMAG SSAG, I usually find I need to check my focus.
It's rare, but sometimes correcting my focus helps Sharpcap snap right to it.
