Thanks Zane. I took a few shots over the weekend, to tune up my system for the SVAA camp this weekend. The 8300 - 200mm combination produces a nice image. Stars look great, but a flatter field would be nice. It would be nice to take in more sky which is a little restricted in my view. This setup in square mode would frame eta C well.
The idea of interchangable objectives, reducers and so on makes the Borg very attractive. And the .7 focal reducer is also a flattener, as it turns out. Borg don't go into a lot of detail at times. The user group is the best resource.
Rowland.
