自作45cm ニュートンの変更です。
自作ゆえに光軸が狂うと言う悩みが有り、毎回調整が日課では撮る気がそそがれてしまいます。
最終光軸合わせをミラーセルで合わせる作業から斜鏡調整ネジの回転で星像を見ながら行う事で煩わしさを解消しました!。
このやり方では完璧でないものの現状では良いと思っています。
ネジは今までのホールセットネジからツマミがあるネジに変えています。
4本ネジでは回し辛いので2本の高さを変え、手で回せる作業が楽で簡単に出来ます!

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!
