I have a Red dot finder, Haven't used it much yet, but now there is a need of it. I mount it on the mount and then it's always there when I change lenses. One problem, I have built the tripod very low to have it more stable and more transportable. Then it's difficult to see through the finder. Maybe a 90 degree mirror can be applied.

I added a map with asteroides:

Maybe there is one in the photo.

Step down rings are cheap on ebay and screw on the end and are say 5mm wide ring. They stop the sun rays effect on bright stars.
