Oag
Hi there,
I have an Orion 90mm Mac-Cas FL1250, and I would like to use an Off Axix Guider to help with my new hobby of astrphotography.
I have read that some of the smaller scopes do not have enough focus travel and will not work.
Orion do make a flip mirror OAG.
Can anyone advise/recomend me?
Thanks
Mike.
