Re: Unfinished Dobson Mirror Mount project for 20x80mm binoculars
I have heard a lot about the 1st surface mirrors not being up to par! I definitely can't tolerate blurry images, what would be the point?! I can only hope for the best, otherwise I might have to go the route of the large secondary telescope mirrors. Probably a little more expensive than I want to go.....SkyHiker wrote: ↑Mon Aug 14, 2023 2:10 am Looks nice. I did the same thing many years ago for a regular photographic mount, probably the same Skymaster 20x80 and found that the optical quality of the 1st surface mirror fell short. The reflected view was too blurry to tolerate. I hope your mirror has a better quality. Otherwise, maybe order some large secondary telescope mirrors, those would certainly be accurate enough.

Thanks for the link. Whew! Not going there!SkyHiker wrote: ↑Mon Aug 14, 2023 10:23 pm Here's a website that lets you specify the size then returns the price. You can specify 1/4 or 1/8 lambda. Best to sit down before hitting "Calculate".
