First frames with my new telescope "Ed. No.3", why 3?
This is my third homemade real telescope, the first two were a Refractor 152/900 based on a TS152/900 objective and an Apo triplet 115/7 also based on a non-liquidated TS115/7 objective refined by Fidel in the basement to a Strehl of 0.99 in red and 0.92 in green, with which I took many remarkable photographs.
Since it's the first light, the device still needs refinement, the stars across the field are not very round, although terminators solve this problem perfectly, and a dew shield needs to be made for the front and before the corrector.
The mirror for this telescope was made by Igor Gribko, huge thanks to him.
A bit about the tube:
Mirror by Igor Gribko, tube made of 0.5 mm stainless steel, reinforced with rings made of 18mm bakelite plywood inside, mirror cell is aluminum and also plywood. The front end is in the Lanikea style by Oleg Chekalin.
The weight turned out to be 15.5 kg without the camera and corrector.
A photo is available in my profile.

Not anywhere yet, but I'll definitely write about it gradually in the Homemade Telescopes section on the astroforum.

The aperture is impressive, with 30 minutes of exposure on such an object yielding excellent results!
