Hello Ed, thank you for the review, brilliant as always. I didn't know that this scope was so rare. I actually own one of them. Mine has a focus rotator though. I bought the Epsilon a while ago used, but have to admit it hasn't seen first light yet, so I cannot say anything about the performance. I haven't even collimated it yet. Although I liked your review - it may even be the only one on the Internet - I was a little disappointed about the performance of the E130, e.g. in comparison to the Sky90 which I also own and love. The Sky90 is the first scope I ever purchased. Your review was not much of an encouragement to use many days for collimating the Epsilon and trying it. But I suppose curiosity will win, and some day I'll do it.
I saw this telescope in the background of one of your videos haha. Cool to see a video of it.
I had a good friend who was a biology teacher from the academy who passed away in 2013. Small world!
Beautiful images and telescope, great review!
LOL As a high schooler I'm always constantly competing with Phillips Exeter Academy in academic competitions... man the bunch is smart!
Jk jk that's besides the point. Man you make some great videos. Honestly surprised that you haven't picked up hundreds of thousands of subscribers. Keep working Mr. Ting, you've inspired me, as a high schooler, to become a better astronomer :)
Ed: How do these images look? Well, let's take a look at this gallery

Me" You got all this through THAT telescope? Astronomy has changed some since the mid to late 70s when I was kid looking through dad's 3" refractor.
Thanks Mr. Ting!
Ed I'm just wondering what you think about the Celestron Edge Hd line of scopes, maybe the 8 or 9.25. I've been thinking about getting one. The Edge series is supposed to have a newer mirror that does away with the coma effect. Love your videos I find them informative.
Hi - if you're a purely visual observer, I'd go with the standard series and save the $$$. The Edge's advantages tend to become more apparent in deep sky imaging.
Great video as always Ed. The system chart for the original E-130/E-160 is on the Japanese Takahashi site.

the epsilon is a great scope on paper but in reality it's very hard to collimated...my E160 with a D corrector actually introduces a big of tilt, I've struggled to get this collimated for a 44mm sensor (when it supports 49mm imaging circle) I would say that if you don't have a a howie glatter, tublug and other special collimation tools don't get touch a Epsilon, Hyperbolic mirrors make it very hard to collimated properly.
Nice colour!
That’s a really nice DSLR image of the North American Nebula.
Well this is teaching me a lesson! Thanks for the fascinating review. The Epsilon 130 is not for me I feel. I won't be able to observe through it that well compared to the Sky90 because of the F3.3 focal ratio not playing well with my eyepieces compared to F5.6 of the Sky90 and I don't like the less than 1" of focuser travel, diffraction spikes and the endless collimation and soft stars (it seems, in your photo compared with your Sky90 photo) and 2x longer exposures needed. I think I would have wasted my money if I had of bought an Epsilon
Hi.Are those images taken without filters dual pass filters etc ?
It's a full-spectrum modded EOS 5D Mk3. I don't use filters.
Is that a Unitron behind you? To your left
Some uneducated comments below. No this is not designed to look through, just for imaging
