Question About Focusing
I have an 80mm F/6 APO refractor and I am trying to get a ZWO CCD camera hooked up with it. My problem is I cannot get focused even when the focuser is ran all the way in. Can I use a barlow to permit focus or a focal reducer? I found a couple posts online but it seems the individuals were more confused than me. I would really like to be able to use the camera with this scope if possible.

Answer My Own Question
Got things out during the day to see if I could get an answer. A 2X barlow did the trick. I was able to focus on things 150' and about a mile away which is close enough to infinity for me. And the clouds immediately moved in, so there is little chance of verifying focus of nighttime objects. I am sneaking up on doing some images with the ZWO camera. Hope to get some spectrae too.:)
