Quote:Does it have a thick heavy single vane spider? If so my first guess would be a Coulter. Although Discovery PDHQ dobs are also blue with focuser on the right. Might be an 8" f/7 PDHQ.

Quote:It looks like its setting on an Orion base, any chance it could be an old pre-Synta Orion?

Quote:Quote:It looks like its setting on an Orion base, any chance it could be an old pre-Synta Orion?Those were made by Pirate Telescopes, which morphed into Discovery. A friend of mine made them, DBA Pirate. The scope in the picture doesn't look to me like a Pirate or Orion scope.
Quote:In this case, I saw you were in New Mexico so I did a search on Dobs...
Quote:My very first Dob was a used Pirate Instruments 8 inch F/6. It was pretty crude, single wire secondary mount and the mirror cell was made from lead for balance...

I asked my friend, and he agrees (i.e. "crude"). But he points out that the scope sold for only $299.
Quote:Is your friend still making mirrors/telescopes ? I have a sneaky suspicion the answer is yes.. Jon
Quote:I suppose it could just be poor focuser and finder placement that is the cause of the discomfort.Interesting you mention cooling, I was wondering about that very thing last night as I watched tube currents morph the star test image. There's no way to get air to the back of the mirror when it's glued to the particle board cell. Is it still worthwhile having a fan back there?
Quote:It's worthwhile have a fan back there.. some holes in the cell, a new cell..
Quote:Looking at the photos, it looks to me like the focuser is at maybe 60 degrees, nearly vertical. I think something closer to 40 degres is much more comfortable.
Quote:Took the 2ndary out for cleaning. Does anyone know who makes this? It looks like a unique design.
