Artemis: A Thin Meniscus Mirror Telescope

[@TheCatull]

Boy I love these stories. All the videos where people document how they crated something incredible often in their spare time are so inspiring.

Thanks for mentioning our products. We are happy to answer any questions folks may have about the silvering process. This is a great video!

Amazing project, Thank you for the video. Would the fast focus possibly lead to the degrade in planetary resolution? I'm no stretch an expert with just a few semesters of astronomy in college but would like to pass the gift of science to my young children. My Prof told me the best telescope is the one you can use and I would like to incorporate this design with something that is more portable or collapsible.

What's coma like at f2.6?

[@metatechnologist]

Super talk wonderful project.

What’s the source of the glass? ATM specialized or thick commercial plate glass?

[@TomOtvos]

Commercial plate glass!

I'm more interested in cost savings as are many rational amateur astronomers.

I am thinking about making a silver mirror Maksutov-Cassegrain telescopes.The problem is i want to look at m42 Orion nebula or crab nebula seeing color right from the eyepiece. You cannot do that with the aluminum mirrors.I have a 90mm Maksutov-Cassegrain telescope and a 8 inch telescope both give results show you cannot see colors right off the bat. I believe that why people stack images through exposures to create colors of said nebula. But i believe silver mirror is a game changer, However today i will get a very expensive Celestron Ultima Edge - 24mm Flat Field Eyepiece - 1.25", but i think it won't make much difference.On a side note, 20 years ago i had a Simmons 20x50 Binoculars before they got stolen. With those i was able to see blue and red from Orion nebulaAny thoughts?

[@TomOtvos]

Pretty sure that colour is not affected by the coating but, rather, your raw light gathering power. If you want to see colour in the eyepiece, you need to be well over 20". An 8" or 90mm just won't cut it.

@@TomOtvos This is good to know. I had a 10" dobsonian back in the day, and I recall looking at the Orion nebula and it was kind of a monochrome... almost a green color. I always wondered why. Where's the reds and oranges and purple colors I see from the photos????. now I know.
