Out of the box, this is a decent 6" achromat refractor with issues that can be corrected. The mount is adequate for visual use. However, the stock scope is very front heavy, which causes the balance point to make the eyepiece height too low for comfortable viewing. Also, the stock focuser is a cheaply made rack and pinion design with a lot of wiggle. I added a Moonlite Crayford focuser to correct the stock focuser issues, a reflex sight to the rear of the main tube, a 2" quartz diagonal and a 2" minus violet filter. These improvements help correct the front-heavy and sloppy focuser issues to make this into a quite nice achromat refractor for visual use.
I have a newton comet f/4 manual cestrone. But will like this better
I am very pleased with this telescope. Sharpness and contrast were far better than I expected. I was able to set up my new telescope and balance it in just over half an hour. I did not have power for the mount at set up so I can't speak on ease of alignment, but the mount and tripod are rock steady. I was easily able to keep Jupiter centered while focusing. Bands and the GRS were clearly visible. Now that I have power for the Advanced VX mount I am looking forward to a clear night of viewing and perhaps a few photos.
I recently decided to resume my childhood astronomy hobby but I was undecided on what telescope to purchase. I researched through dozens of telescope reviews, expert comments, and the opinions of friends. I finally decided to go with a refractor and chose this telescope because, well, who wouldn't want a 6" refractor telescope?! It only took about 45 minutes to unbox it and get it set up on the mount, including getting it balanced. I don't have power for the mount yet so my review is for the telescope only. I took it outside to enjoy a beautiful clear sky before the clouds rolled in. Jupiter was the easy target. I had done the set up after dark so the finder scope was not aligned. No problem though, I pointed my brand new telescope towards Jupiter and much to my pleasure there was Jupiter not quite centered in my view. Focus was easy, and absolutely crisp. With the 20mm eyepiece (60x) the bands were easy to see as well as a beautiful string of moons on either side. I looked in random areas of sky just to see what I would find. Lots of pinpoint clear stars! As hoped there were no diffraction spikes and the contrast was awesome. When viewing Jupiter chromatic aberration was visible only because I was looking for it. If I had not known it could be present I never would have noticed. I definitely am pleased with this purchase. Just a brief note on the mount: rock steady! I could focus without having to deal with a shaky image from touching the scope.
I purchased this lovely refractor for myself at the end of the summer with the intent of delving a bit into astrophotography. Though I've used computerized reflectors for sometime now, I wanted something different. I have been EXTREMELY pleased! The assistance I got from the salesperson at OPT was OUTSTANDING. Honestly, I could not have assembled all of what I need for what I want to do with my new scope without his help. He listened to what I wanted, recommended, then listened some more. What great customer service! I will admit that I initially struggled for several viewing sessions aligning the telescope with the Advanced Series GT ~ NextStar computer that comes with the mount. (Honestly it's more likely the operator not knowing her names of stars more than an issue with the program itself.) I later broke down and purchased the StarSense Camera to work with NextStar and totally LOVE it. I can be set up under non-optimal conditions such as in-town or at dusk and be ready to view in just minutes. The quality of the refractor is very sweet. I'm simply a beginner in photography, but I've taken some pretty good pics of the Moon and Sun (with the aid of a solar filter).
