Polar alignment using OAG instead of Guide Scope
Posted: Wed Jul 20, 2022 9:58 am
HI, First sorry if have this in the wrong section, wasn't too sure which one to go with.
So i was looking at changing my setup from a guide scope to an OAG.
My scope is a Skywatcher Esprit 150 ( I have a .77 reducer, but to keep things easier, just referring to it without for now )
My guide camera is ZWO asi290mm mini
Guide scope is Orion 60mm
Everything works well, guides well polar aligns well, ( if i setup close to being right, have had a few times when i was too far out and it wouldn't polar align )
I picked up a standard ZWO OAG and tried it out, but no hope of polar aligning, I am thinking with the narrow field of view of the asi290mm mini working through the OAG, it isn't getting a wide enough field of view.
Is this correct?
Should i be looking for something like asi174 with a wider field of view?
Or should i be looking for a camera with a similar field of view as my main imaging camera?
This is the first time working with a OAG, and just trying to get it to work with the polar alignment setup.
Any advice would be appreciated.
Thanks.
