Orion 150mm OTA

Dec 15 2009 09:37 AM | Guest in EQ Newtonians and Dobs

I wanted to see larger, brighter planets and deeper into space. After much searching, and the typical modest budget, I settled on the Orion 150mm optical tube assembly. I thought it would give me the biggest light gathering bang for my modest budget. And, it does...with a catch

GSO 200mm F/4 for Imaging

Jul 13 2007 02:12 AM | mikefulb in EQ Newtonians and Dobs

I have been looking for an imaging telescope with a medium focal length (800-1000mm) and a fast optical design.

Starmaster 20", f4.3, Sky Commander & Sky Tracker Goto Drive

Mar 21 2005 01:15 PM | Guest in EQ Newtonians and Dobs

Let me start by summarizing my view on the Starmaster 20" f4.3 Telescope with a 1.6" thick mirror and the Sky Commander with Sky Tracker goto drive: It is the ultimate portable large aperture telescope. It is not the minimum required, nor is it even necessary to enjoy astronomy, but it is the best blend of compromises that must be dealt with in selecting a large-aperture telescope.

GSO 8" f/4 Newtonian + Baader Coma Corrector

Mar 22 2005 03:35 PM | Guest in EQ Newtonians and Dobs

Collimation in an f4 telescope is extremely critical, so I took my time to do it right immediately. I took out the mirror from it's cell and put a mark in the center to aid with collimation. During daytime, I aligned the secondary with the focuser, and the primary later on, all with a Cheshire eyepiece.

Ten-inch Teleport

Mar 21 2005 11:53 AM | Guest in EQ Newtonians and Dobs

The ten inch Teleport is a unique high-end altazimuth newtonian made by Tom Noe of Wylie, Texas, and incorporating an F/5 primary mirror by Carl Zambuto. I first became aware of the Teleport from Todd Gross's review at www.weatherman.com in which the Boston-based equipment guru writes that if he could have only one telescope, it would probably be the Teleport. That statement got my attention. Having become interested in astronomy about a year ago with the purchase of a Celestron C5+ Schmidt Cassegrain Telescope (SCT) I had decided that I really needed more light-gathering power. The C5+ was a great first telescope, but after about six months I was longing to see more detail in deep space objects (particularly globular clusters and nebulas) and craved better contrast for high-powered planetary viewing.

Orion Optics GX250 F/4.8 Newtonian

Mar 23 2005 10:45 AM | Guest in EQ Newtonians and Dobs

I've been a "serious" amateur astronomer for 15 years and a member of the Norwich Astronomical Society (NAS) for most of that time. Finally I thought it was high time I bought myself a telescope. Being primarily a "faint fuzzy" observer I decided that a fast newtonian

Meade 8

Mar 23 2005 10:46 AM | Jan Owen in EQ Newtonians and Dobs

While other scopes in varying sizes and specifications have come and gone from my collection over the years, the above scopes are among five which have stayed, and these two have been the nucleus of my battery and in constant use for many years.

Orion Skyquest XT4.5

Mar 23 2005 04:59 AM | John Kocijanski in EQ Newtonians and Dobs

Throughout the night I viewed a number of deep sky objects that included M15, M31, M27, M56, M11, M 57, and the Double Cluster. Each view was crisp and clean. I also viewed a number for double stars that included Mizar, Nu Draconis, Almach, Eta Cassiopiea, and Gamma Delphinis.

Rat Notes - 18" Starmaster Review / Obs Report

Mar 21 2005 12:51 PM | Guest in EQ Newtonians and Dobs

Anyway, things have been a little hectic, and I've been remiss in posting notes. I do plan to get back into it. Here are some long overdue notes, and a general review of the new 18" F4.3 Starmaster Dob. I am skipping over many observations for lack of time, but I'll try to do some more 'normal' reports real soon:
