Certainly a "novelty" eyepiece in many respects by today’s standards with so many fast scopes on the market as a 55mm eyepiece produces a rather large exit pupil, these eyepieces are still very
The tapered recess on the 1.25" barrel of a number of Baader Hyperion eyepieces is too big. This may interfere with your focuser's or diagonal's compression ring where the eyepiece cannot firmly be secured. If you use a setscrew or you use the 2" sleeve, then this does not apply.
If you have a moderately fast Newtonian reflector and feel in need of something in the way of an eyepiece upgrade, but don’t want to wear out the credit card too quickly, consider Orion’s Stratus eyepieces.
My acquaintance with zoom eyepieces dates back in 2001 with the purchase of my Leica 22-7.3mm Zoom for my Leica Apo-Televid 77. In 2003 I got my first astronomical telescope, a 115/805mm TMB/APM apochromat. The Leica Zoom was
I got the whole Q-70 set for Christmas in 2007. I have had a chance to put them through their paces on many occasions in 2008 and 2009 and have learned their ins and outs. The 2" format really
It is hard to compare these eyepieces to anything else, since I have only owned this set of eyepieces. With that said, I couldn’t be happier with my purchase. For the price, you
I bought this kit as I was getting into astronomy and it increased my eyepiece collection from 2 to 6, added a barlow and got me fun filters to try. I believe this is
I was struck with aperture fever and I sold that scope in order to purchase a mirror blank and material to make my own telescope. But I kept the good eyepieces. A few months later and my 12 inch reflector saw
While this eyepiece is great for wide angle viewing through a 10" SCT, this is not a great eyepiece for use with
On daytime targets, the eyepiece seemed to work well with my 120mm f/5 achromatic refractor. The eye relief is given as 28mm and that seemed about right to me. The view didn't
I received the Baader 13mm Hyperion in 2007 and was amazed by the sheer size of it. The cost of the eyepiece was
This is one of my go to lens for faint objects, as it has enough power to resolve, but not too much as to dim the object. I can see much more detail in
This lens is from the classic Televue Nagler series. It is in the 2 inch format and has a focal length of 17mm. It has an 82 degree apparent field of view that gives incredibly wide views. The lens has a
Once upon a time there was a fellow with a newly acquired 10" F10 Schmidt-Cassegrain telescope (SCT). Being the largest aperture scope he'd had the pleasure of using, and having been
I'm going to tell you a story between the serious and the facetious for the monocular amateur astronomer
I am relatively new to astronomy but wanted to add some capability to my Orion XT8 scope. The Orion comes with two moderate
I have used this eyepiece at public star parties and the reactions have been very good. People have asked why it seems like they are seeing stars everywhere in my scope while in other scopes they see only a small area of stars. Using this with m
Now, I understand I might be comparing apples to oranges here, but please be aware that I am interested mostly in astrophotography of basic objects (moon, planets, some easily visible clusters and nebulae) with a point&shoot camera attached via
As many are aware, the TMB Supermonocentric eyepieces had multiple runs by the factory. The 1st run eyepieces were not parafocal, while the subsequent runs were parafocal; and blackening and baffling were also improved in
I was looking for the a widefield lowcost scanning eyepiece for my 80mm FL 11.4 Celestron Firstscope refractor in the 1.25 eyepiece size. The eyepiece is threaded for filters unlike some
How do you tell the difference between any 13mm eyepiece and a Televue Ethos 13mm eyepiece? View the sky
I purchased a 9 MM Eyepiece for my nephew as an upgrade to the existing eyepieces that came with a reflector scope I bought him last year. Here are the top reasons for my selection
Discontinued only recently, Orion’s "Explorer II' series of eyepieces served for more than a decade as their "bargain" eyepieces for beginners or astronomers on a budget. Listed in the
I’ve seen this question come up again and again on Cloudy Nights: "What’s a good low power, wide view, eyepiece for a reasonable price?" As an owner of a long focal length SCT I’ve asked this question myself because I’d like to be able to get to lower magnifications to view some of the larger objects in
After finally pursuing my curiosity in astronomy this summer, the requirement to upgrade from my two plossl's was evident to bring my Orion XT8 to maximum potential
