My Christmas present this year (2018) is an Orion EON 130mm Triplet. My previous imaging setup was comprised of an Orion 10" f/3.9 astrograph. I have had fun with and was very satisfied with this setup, except for star images. I spent an evening with a friend that has a 130mm EON and upon processing the images and seeing the pinpoint star images I was sold. If anybody out there has one of the EON Orions of any size, I'd be interested in any feedback I can get. I am currently using a modified Canon T3i but by summer I think I'm going with a monochrome CCD camera. I live in Tucson, AZ so dark skies are plenty. Attached images were taken with my 10" reflector.

Sounds like a great Christmas present! Refractors always give the nicest star images IMO. The EON 130, Meade Series 6000 130mm and AstroTech 130mm are nearly identical products made in the same factory in China. They are excellent performers both optically and mechanically with slightly different features depending on which one you choose. The Eon is probably the best choice of the three for Astrophotography because its 3" focuser will allow a larger format camera without vignetting. The Meade and AstroTech have 2.5" focusers and you need to use the optional field flattener to cover full frame 35mm.
The only complaint I have with mine is that the focuser tends to get a bit stiff below about 15F. Otherwise I wouldn't change a thing.
Enjoy!

Egad, -15 F? It doesn't get that cold in my freezer! Here in Southern Arizona cold is anything below 50 F !!! Thanks for the response. Clear skies and Happy New Year.

15F, not -15, but still cold. We are going out tomorrow night, expecting low twenties dropping to teens. We don't do outreach below 20F, but the hardcore of us do observe
