Change of the self-made 45cm Newton oblique mirror adjustment screw

It is a change of the self-made 45cm Newton oblique mirror adjustment screw. I have a problem that the optical axis is out of order because I made it myself, and I am discouraged from taking pictures every time I make adjustments in my daily routine. From the work of aligning the final optical axis with the mirror cell, the troublesomeness has been eliminated by performing while looking at the star image by rotating the oblique mirror adjustment screw! This method is not perfect, but I think it is good at the moment. The screws have been changed from conventional hole set screws to screws with knobs. Since it is difficult to turn with 4 screws, you can change the height of 2 screws and turn it by hand easily and easily!

45cm telescope scenery

45cm telescope scenery. Last night, the polar alignment of the equatorial mount was performed for the first time in 5 years in order to improve the period deck motion of star tracking and improve the accuracy of automatic introduction. Equatorial mounts that are not aligned with the polar axis are out of the basics! The telescope landscape has been HDR processed to deceive the surroundings.

45cm Mirror

Upgrade to 45cm reflective F / 4, first image is M42. Iso1600 ’10 seconds exposure, images from 20 images, but you can see the light intensity of 45cm. Although there is a rework part, I was relieved that the accuracy of the mirror seems to be good

Telescope Hangar Repair

My 40㎝ telescope hangar was modified from an inexpensive bicycle hangar because it was only used for a certain period of time, but it has been damaged. In this repair, the ceiling is raised 30cm, so I can observe more smoothly when using a telescope.
