Quote:I want a high quality secondary but the 2.6 inch Antares and protostar are a bit smaller then 70mm. Will this cause a loss of illuminated field?

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Quote:Did u guys have to buy a new secondary holder?
Dan Orion XT8g If your dob isn't broke, fix it anyway. Don't tell me what I want to hear, tell me the truth.
Quote:What could I ask for the stock secondary? 30?
Quote:I've compared standard diagonals in refractors to high end diagonals and to my eyes the difference is obvious. Hoping this will be just as obvious. Subtle but clearly better. Well if there's no resale value I won't bother w the hassle of taking pics and making an ad then boxing it up going to post office. Keep it as a backup just in case.
