An internet friend of mine is an astronomy professor at Case Western, and he posted a link to a picture of their telescope at Kitt Peak. I thought some of you...
... Hi, That depends on the Apparent Field of View (AFOV) of the Eyepiece. A simple way to approximate it is to divide 2800 by the AFOV, For instance, if we...
It depends on the eyepiece AFoV, but a 56mm Plossl is the longest I've seen. Doug ... -- Doug Truckstop Astronomer [Non-text portions of this message have been...
... While this is 100% true, my personal preference is for a shorter focal length combined with a wider apparent field of view. On my 11" SCT, I particularly...
True enough, but then he did only want to know the longest unrestricted by the 2" barrel, not any preference to which one to use, BTW Geoff, how would the MK70...
... WG: Like someone else said, it depends on AFOV. I have eyepieces beyond the normal including 48mm, 55mm, 60mm, 75mm, 100mm and 125mm all in 2-inch barrel...
... There must be. My first scope was a Kmart 60mm refractor that had solar filters for the eyepieces. I never had a problem with mine an certainly used them...
I'd like to hear more about your eyepieces. I assume you use them on a refractor as the obstruction of a Newt would look horrendous at 60mm and up. What AFOVs...
First of all, hi to every one, I'm new here (and sorry for my bad english!) I'm from Spain, and I'would like to adquire a Santel MK91 so, do you know if there...
Welcome! For info: there's a Yahoo Group dedicated to Santel Maks (actually RUMAKs, Rutten-Maksutov designs): http://tech.groups.yahoo.com/group/Santel-Maks/ ...
Hi, My two cents. Unless you have 5" or larger optics and a fairly long focal length, or eye problems I feel 2" eyepieces are worthless. It's an added...
I got 3 new Stratus Wide-Field eyepieces in the mail yesterday.When I opend them I was impressed by their quality and the 2" wide-field design.Mother nature...
Simple question. Which scope would be better for entry astrophotography using a Canon XSi on a G8 mount? My budget is under $800. Optics and mechanical quality...
The Meade and Explore appear by all accounts to be the same scope, with Explore's version having a 2 speed focuser. Because of the focuser, and the very good...
... WG: That was the original intention Al. There are a lot of misconceptions about such eyepieces as few people have owned, looked through or used them...
... While in general much of the advice you read on eyepiece choice and exit pupils is very sound, and probably applies most of the time to most observers,...
... I have the 13mm Stratus that I picked up about 4 years ago. I have to say it is one of my favorite EPs. I do tend to prefer the Baader Hyperion version a ...

WG: Hi Geoff, it seems that we end up being the only ones to discuss a lot of topics on a couple of groups these days! That is OK, nothing wrong with that....
From: "Wayne G" <fomalhaut@...> ... I for one don't mind sitting back and reading what the rest of you have to say. That's how we learn from a variety...
... These telescopes were usually "stopped down" by an internal baffle to about an actual 50mm going by an old "Consumers Report" I still have. With this small...
Geoff, Takahashi makes a similar recommendation. The manual that came with my Takahashi FS78 states under: "Planetary Observations", that on nights of...
