Today's noob question...

 

Can you do sharpcap polar alignment using the main cam, in this case a qhy168c?

I do it all the time.  I use short subs and guiding is not necessary (not limiting) for my system. There are some constraints to this.

 

1. Primary sensor has at least 0.5 degree field of view ... Sharpcap constraint.

2. You can adjust your polar alignment with the added weight of your optics train.  This is a mount constraint.

My current mounted OTA is a newtonian with 0.85x0.58 degrees FOV and SharpCap 4.0 64 bit is fine with polar alignment.  My 1.11x0.76 degree FOV refractor had no problems either.

 

I do make sure I start the alignment at least 3 degrees East (or west) then move at least 3 degrees the other side to complete the alignment process.

I use an OAG so when I do want to double check my PA I use my main camera the ASI1600MM-Pro in SharpCap and it works perfectly. But I do have 3 marks on my deck so I just place my tri-pod down on the marks and use my polar scope 9 out of 10 imaging sessions and I average around 0.45 RMS..

Thanks for posting.. I have the same question.
