Quote:Hi LarryYeah, I can imagine the pain in trying to get a threaded ring of that size into the cell without cross threading - I'm glad mine has the bolt on retaining ring. Any idea, roughly, of how many Dx6s were made compared to the Dx8. The Dx8, from what I can see, seems to be more common so going by your serial number maybe they did keep with the sequence?Also good to hear that there are good Dxs out there, it's a shame the production quality seems to have been so variable. I think mine is reasonable, I probably need to touch the collimation up a bit but it's difficult getting clear nights here with good enough seeing. How have you found the cool down time? I've heard they can take quite a while to cool down, longer than Celestrons for instance? I'm toying with putting cooling fans in mine similar to what was done in this thread. James

Quote:O.K. I've got to ask. Who is Fred Pauli and what is his site? I do a search and all I come up with is a therapist. Is it someone in our community or.....?
Quote:It made a difference when i flipped it, BUT it may have been due to rotating the corrector on it.. I didn't know better back then.Did you Criterion mark the corrector/cell with an alignment mark like Celestrons (it is at the 3:00 position)
Quote:Very interesting...... But STUPID!!!! The corrector does indeed correct...
Quote:Hi AndyQuote:Very interesting...... But STUPID!!!! The corrector does indeed correct... At least this helps defend against the statements that the Corrector was just a flat sheet of glass in the Dynamaxes! James
