    Default Meade 90mm Infinity refractor? (Meade Infinity refractor Series)



    Hi List. Anyone out there actually used any of the new Meade Infinity Series Refractors? I was considering the 90mm f6.7 for a decent grab and go scope. Not allot of info on the forums about the Infinity Series. I would get the optical tube assembly and mount a longer dovetail so I can use it and provide better balance on my mount. The f6.7 falls into the medium focal length so it should do well for wide field nebulae, open and closed star clusters as well as fair for high magnification of the Moon, planets and a bunch of deep space objects. Just wondering about the quality of the optics. Saw one short review praising about pinpoint stars. I'm not overly concerned about the chromatic aberration for visual observation as I will be using a Lumicon Minus Violet Filter. Just thought I would see if anyone has tried these scopes out.
    Cheers and Happy Thanksgiving 2014

    Hi Don,

    Hope someone who has actual experience with the Infinity 90 can chime in. I have a 90 mm Mead DS2090AT f/8.8 refractor (Star Navigator 90mm Refractor). Optically it does very well for an entry level telescope. Planets are very tiny but you can see the cloud bands of Jupiter, rings of Saturn, details on the moon, etc. For deep space it does well for double stars, open star clusters, globular clusters and the brighter nebulae and galaxies. The only real complaint I have about it is its plastic focuser which is very stiff. I have no idea what kind of focuser the Infinity uses. The three eyepieces ought to cover the scope's viewing range quite nicely. The red dot finder, well it's a red dot finder but one heck of a lot better than Meade's 5x24 finder scope; I have both.

    Meade also has a short tube 80 mm refractor in the line. I have an Orion ST80 which is very similar to the Meade Infinity 80. My Orion ST80A has worked its way up to my favorite scope in my collection. This scope is excellent for portability and for rich field views of deep space. Unlike my Meade refractor, the Orion refractor's tube and focuser are made of metal and the scope is a quantum leap better in quality in comparison to my 90mm Meade. I have no idea how the Meade Infinity 80 is constructed.

    You may want to look at the Orion Starblast90 which has pretty much the same specifications as the Meade Infinity 90. The Starblast 90 gets excellent reviews. A couple of members have the StarBlast 90, perhaps they will comment.

    Finally had a chance to look through the eyepiece of the Meade Infinity 90mm refractor. The views were very sharp using a 25mm Parks Plossil at 24x! Stars were pinpoints. A look at the full moon was also very crisp and sharp, however Chromatic aberration had some yellow fringes of color on the edges of the Moon, which surprised me as I was expecting a violet or light blue. When I centered my eye on the eyepiece the yellow would go away. This could have been caused by light atmospheric dust or pollution, but seemed like a pretty clear night sky to me, but now that I think about it there was some twinkling of the brighter visible stars which could of been some kind of atmospheric disturbance be it fine clouds, dust in the air or some kind of pollution. Bright stars such as Sirius had very little blue fringe and easily tolerable Chromatic aberration. I will check again on a moonless much clearer night. Dimmer stars showed zero Chromatic aberration. This is all expected with double element objectives and short focal length fast refractors. Checked the Orion M42 nebula and was able to see crisp whisperings of the nebula even with the full Moon with in about 20 degrees of Orion. I am sure my Lumicon Minus Violet filter would have corrected most of the Chromatic aberration but I did not use it to test last night as time constraint was working against me. I will try again, but this time using the Minus Violet Filter using a higher magnification and report my findings. A quick view of Jupiter showed a very clear sharp bright disc with 3 moons easily visible and bright & sharp. I did not see any belts on Jupiter but at only 24x and a full Moon to deal with, I didn't expect to. Overall I was very pleased with my initial performance of the Meade Infinity 90mm, especially the wide views which were spectacular. As a quick grab and go scope I think this scope will suffice. Looking forward to a moonless night to view some open clusters and a few DSO's using much higher magnification as a real test of which I will report back as well. So far so good for the price....
    Cheers
    Don
