CouldnÂ´t figure out how to focus the main optics. No manual here to help, either. Another user taught me how to focus: you have to hold the front lens cover and unlock the very, very, very tight knurled locknut. Then it was a piece of cake. After focusing, it gives very sharp images. It has a decent field of view and good quality images. One minus side is that thereÂ´s almost no extension over the lenses, so lotÂ´s of stray lights enter the main optics. IÂ´ll use a cardboard tube to make an appropriate shield. YouÂ´ll also need an allen (internal hex) key to adjust the aim once or twice. Very nice and quick to release dovetail base. All in all, a fine product, with no instructions. Hence the four instead of five stars.
This thing can sometimes give me better images than my C8 telescope! It was fairly easy to install, the only hard part was figuring out how to get the thing to stay in place. Also, one of the adjustment screws cannot be turned by hand. Otherwise I'd give it 5 stars. The illuminated reticle is FANTASTIC. It's one of those things where you wonder how did you live without it.
Bought this for my Celestron Nexstar 8SE and received it today. It comes complete with mount, batteries, no instructions or mounting screws. It is a 9x50 finder in case anyone wanted to know. It is quite well built and heavy. It has for me a heavy mount, not plastic but metal. The cross hair lighting is controlled with a potentiometer, not a step type switch. Mounts fairly easy on the 8SE tube. Only issue was mounting it with the Celestron mount for the camera. The camera mount is plastic and I had to grind off some of the plastic to install both the finder and the camera mount at the same time. After a little work they go together just fine. I do not think the weight carrying ability of the camera mount was compromised. Visually it makes the 8SE look like a real scope unlike the cheap finder it comes with, which was very awkward for me to use. I am looking forward to using this finder for a long time. Adorama's price and delivery, as usual, was excellent. Hope this answers some of the questions as the advertising for this is extremely limited!
