Zeiss Filters

Mar 12 2005 05:18 PM | Gary BEAL in Astronomical Filters

I have been thinking for some time now to share my experiences with the selection of filters designed and manufactured by Zeiss. It has taken some years to acquire these filters, and while not a prolific filter user it is nice to get them out and give them some fresh air every now and then. They are all designed for the Zeiss

William Optics 45-deg Erecting Prism

Apr 04 2006 02:03 AM | Silicon Owl in Star Diagonals

Out of focus stars seemed a little odd but I couldn't quite determine what was wrong, in focus the stars were sharp until near the edge, but that I expected with the short focal length telescope

The quality of a telescope is often first judged by its optics, but other parts of the telescope play an important role in the user's satisfaction with the scope.

Who Needs a Crayford Focuser for an SCT? Maybe you do… The William Optics SCT Crayford

Mar 12 2005 11:13 AM | rmollise in Focusers (Electric and Manual)

Crayford focusers, those no-gear super-smooth wonders so favored by the Big Dob folks, have finally started to make their presence known in the SCT community. Now, why would a Schmidt Cassegrain owner want a Crayford focuser? SCTs have built-in focusers that focus the telescope by moving the primary mirror. Why the H - E Double Ell would anybody bolt an additional focus unit onto the back of the SCT rear cell?

Virtual View Adapter

I hate set screws. Set screws have a tendency to mar any equipment that they are tightened into like a diagonal or nose piece.

Useful Filters for Viewing Deep-Sky Objects

Mar 12 2005 10:40 AM | David Knisely in Astronomical Filters

The broad-band "Light-pollution Reduction (LPR) filters are designed to improve the visibility of a variety of Deep-Sky objects by blocking out the common Mercury vapor, Sodium, and some other emission lines from man-made or natural sources which contribute to light pollution, while letting through a broad range of other more useful wavelengths. Since the eye is mainly a "contrast detector", this selective screening out of some of the background skyglow increases the contrast and helps Deep-sky objects stand out more noticably.

Thermodyne Telescope/Mount Cases

Mar 12 2005 12:29 PM | Dave Novoselsky in Cases

Sometimes your friends turn you on to some really good ideas. I bought a 203mm f/9 Apochromatic Refractor from Tom Back at TMB Optical. It was delivered to me by Tom at Astrofest this year, in its original shipping case (i.e. a cardboard box.) Tom said Markus was going to look into a case for it, but the cost of having one built in Germany and then the cost of shipping it here seemed prohibitive.

The Return of the Denkmeier

Mar 09 2005 02:51 PM | rmollise in Binoviewers

By way of background, before I had the chance to test the 2" Denkmeier, I was not much of a fan of binoviewers in general. I had never had much success using them. I couldn't ever seem to completely merge images, and the resulting eyestrain and headaches meant I avoided them like the plague. However....

The Aries SAFIX

Mar 11 2005 05:28 AM | rmollise in Abberation Correctors

Spherical aberration is something that troubles amateur astronomers no matter which design of scope they use. In any telescope, if the objective, primary mirror, or combination of lenses and mirrors yields a final image that is too much like what is produced by a spherical mirror or lens, you’ve got Big Problems in River City. All rays of light will not come to focus at the same point, meaning your images are not and never will be sharp.
