New Celestron Ultima / Axiom EP reviews?

Posted By Phillip Creed

Has someone purchased a new Celestron Ultima LX or Axiom LX eyepiece and tested it in a fast Dob? I'm mildly interested in getting a "finder EP" and the 32-mm Celestron Ultima LX sounds like it might work, but there's just no reviews out there I could find.

Ultima LX 13mm Comments

Many thanks for doing a review of the new 13-mm Ultima LX. I've been scouring around looking for reviews on these EP's (particularly the 22- and 32-mm versions).

druthers; ES AR102 refractor vs orion Starblast 6i?

Posted By Phillip Creed


Tough call. There are several pros and cons I can see with either package.


(1) Quicker cooldown vs. 6" mirror
(2) Lower focal length (663mm vs. 750mm) allows for a little wider FOV
(3) Ability to use 2"-eyepieces allows for MUCH wider FOV
(4) Higher f-ratio is easier on eyepieces, particularly widefields

(1) Chromatic Aberration. Not terrible, but definitely there. Can be offset somewhat by minus-violet filter
(2) Less aperture than the 6" Starblast
(3) Might be too low an eyepiece position when aimed towards zenith.

6" Starblast:

(1) More aperture than AR102
(2) Relatively lightweight
(3) Intelliscope design allows for quick location of DSO's
(4) No chromatic aberration. Zero. Zip. Nada.

(1) Longer cooldown vs. AR102
(2) Barely half the FOV as the AR102, owing to a longer focal length and limited to 1.25"-eyepieces
(3) Rack-and-pinion 1.25"-focuser leaves much to be desired. Can be swapped out for a 2"-focuser, but will likely require a dremmel tool and greatly ramp up the PITA Factor.

New format needs work.

Just to add one more complaint onto the pile...I lost all my astromart ratings.
