I haven't tried them, but that is one short focus scope you got there. I use some Plossls in my 6 inch f/5. The 25mm gives some pretty hairy coma. ... ...

Anybody here used the KineOptics HC1 or HC2 focusers? They really look nice and my figures so far show me the HC1 is going to let me reduce the secondary size...
Hi, Just joined the group and looks to be a good site. I have a Celestron C10-NGT. Its a lovely scope. I use it mostly for astrophotography. Just added an...
Welcome aboard. Sounds like we might all learn quite a bit from you. And that's just fine too. I don't have anything quite that big or sophisticated. I use an...
Let me know if you ever see bands on Jupiter with it and how you accomplished the feat. I haven't been able to do it yet and I live outside of the city....
Frank, It sounds like your scope might need to be collimated. A 10" should surly show bands on Jupiter. John "Frank R. Skroh" <zxlp@...> wrote: Let me...

If I re-gring my 10" mirror to a long enough focal length (high "F" number), I wouldn't have to parabolize it. Collimating would be easier, so they say. I...
That is true Frank. But I wonder if a compromise might be worth considering. A longer, but not long focal length. Maybe f/7 or so. It would need to be ...
