TPO 180 lens
Very easy to use, lens, helped me solve focusing issue compared to a dslr lens
Great little imaging scope that’s perfect if you’re on the go!
I’ve only been able to image with the scope one time, but wow, did it deliver! I used an astromodded Canon EOS 60D, a SkyGuider Pro (unguided) and the TPO 180. I used the ASI Air for polar aligning and running the imaging session. Without guiding, I was limited to 3 minute subs and there were 35 of those. I also shot 10 darks, 20 bias and 20 flats. I processed in Deep sky stacker and then went to work in Photoshop. Bottom line: This little scope makes it REALLY easy. The portability factor cannon be denied. If you’re looking for a mobile, lightweight wide field solution, this is a great option for you.
I've had the TPO 180 for about a month and have used it for both visual and photography. It's a bit tricky to get set up but I did my first photo session last night and I'm happy with the results. As mentioned other places, back focus is tricky and not well documented. I used the scope+reducer/flatner+medium sized extension tube (included)+an M42M-M48F-16.5L adapter (came with my camera)+ASI294MCPro and found focus in the middle of the focusing range. The build quality is very good; portability is great ... It's going to be a fun addition to my arsenal at f=180! Attached photos show the setup on my AVX mount (along with guide camera and ASIAir Pro); imaging setup without camera attached; and first results
Using it primarily as a finderscope with intentions for astrophotography. One suggestion for upgrading this package to differentiate it from the Askar 180: an Arca-Swiss/***** plate instead of just Arca specific and a brass compression fitting rather than than set screws for holding accessories. Beautiful scope nonetheless.
This is a great little scope
While still new to the hobby of Astrophotography, I was looking for a lower focal length lens to use, while I traveled up to the Boundary Waters Canoe Area MN, a bortle 1 area. Due to size needed for the trip, I was looking at maybe getting a 135mm lens, but then this little guy came back in stock, so I decided to go for this instead. I am glad I did! This scope is small, fits perfectly in my little Pelican Case used to transport my camera and Skyguider. The scope is very well made, feels extremely sturdy and the focuser is solid, maybe a tad tough to move, but nothing to write off about. Along with the scope came some extension tubes and nice blue mounting rings that mount nicely to the arca-swiss dovetail. If you are in need of an ultrawide, I highly recommend this scope. The attached image is only 37.5 minutes at ISO 3200 of the Pleiades.
