| AP Drones....weird, dangerous and apparently... | 31 Aug 2005 16:41 GMT | 22 |
obsessive circle jerkers. Somebody placed tests of a number of refractors on the Yahoo Refracor Group which gave TEC high marks and AP not so high, albeit, on what was described as a pre-production model. However, that was enough to set the "AP Mafia" into a rage,

| The American economy | 31 Aug 2005 13:40 GMT | 22 |
If the American economy is so flat, (as Liberals jump to point out) then how come wait times for scopes like AP which are luxury items and a bell-weather of economic health are so long now? In the 1990s, you could get an AP in about 2 years, now it's 5-8 years.

| S&T Going to the Dogs | 31 Aug 2005 08:04 GMT | 5 |
Has anyone noticed the horrible new paper in the October issue of S&T? Its overly slick glossiness totally lacks the charming, pulpy texture I was used to from the preceding issue. Bah!

| What did I just see ("line in the sky") | 30 Aug 2005 16:46 GMT | 7 |
It's about 9:30 p.m. local, and dark. We just got back from the cottage. Unpacking, I looked up and saw what I thought at first was a faint jet contrail, light by the sun that had gone below the horizon. The line ran, as far as I can judge, from due south towards north, and

| Grating Spectrometers for telescopes | 30 Aug 2005 08:35 GMT | 13 |
I recently found and then lost a URL to a grating spectrometer for amateur astronometers. It was modest priced in the $150 range. Can someone help me. Thanks in advance.

| 100 Billion Brown Dwarfs in the Galaxy | 30 Aug 2005 04:57 GMT | 3 |
After decades of searching, astronomers discovered the first definite brown dwarf only ten years ago. Now, a new analysis of Hubble Space Telescope data implies our Galaxy has almost as many of these failed stars as it does normal stars like the Sun.

| TeleVue Dioptrix | 30 Aug 2005 03:32 GMT | 1 |
Tele Vue has a new accessory http://www.televue.com/engine/page.asp?ID=259 that fits over an eyepiece and corrects for astigmatism. This costs about $100. You have to order one with the correct diopter correction

| Split ring mount | 29 Aug 2005 22:52 GMT | 4 |
I've been looking at equatorial mounts for large aperature telescopes - especially newtonians - and it seems to me that the most stable are split-ring mounts. But noone really makes them, so I have to wonder about their usefulness. Are they stable enough for astrophotography?

| Celestron vs. Lumicon Oxigen III filters | 29 Aug 2005 21:33 GMT | 4 |
I had great views tonight with the Lumicon O-III filter on Veil nebula and others.Now I want to buy one. Seems, the Lumicon O-III is twice the price of the Celestron O-III, searching on the net.

| Lens adapters | 29 Aug 2005 08:55 GMT | 1 |
I have a 360mm Mamya RB67 lens that I would like to use for CCD imaging. To do this I need an adaptor for a 1.25" nose piece. Does anyone know if such adaptors are available.

| Barlowed F5 vs. F10 achromat | 29 Aug 2005 01:01 GMT | 6 |
Is the color error in a barlowed F5 crown/flint achromat (eff. F10) the same as an actual F10 crown/flint doublet? Trying to decide between an F5 achromat with 2x Binoviewer, or an F10 with 1x binoviewer (I will remove 5 inches from the tube).
