I have an old Edmund 4 inch F15 refractor from the late 60's which has been stored for about 15 years. The lens, especially the interior surfaces for some...
Try miking the one undamaged spacer and check aluminum foil for approximately similar thickness. Different brands seem to be different thicknesses and there...
There is now a short article about the 1970s and 1980s Sears, Roebuck & Co. 60mm Discoverer altazimuth refractor telescope. A popular scope sold by Sears, it...
I thought a micrometer would be pretty expensive, but I found a very nice set- a 3" micrometer, 6" dial caliper, and 6" steel ruler graduated in 64th's of...
Greetings Refractor Fans, There's a rare Pentax 6" f12 refractor for sale at K. Kohki in Japan. http://www.kkohki.com/used/useditems.htm At 898,000 Yen, the...
Do you know if that includes the mount? Larry ... From: brooktrout717 <brooktrout717@...> To: Refractors@yahoogroups.com Sent: Mon, 07 Nov 2005 23:57:01...
David; Seeing as how nobody else has tried to answer your question I will give it a try. My answer is based on section 6.2.1 of the book "Telescope Optics" by...
Hi Ed T I can imagine how much the 10" version was! Ouch! Nice looking scope, though. (And that's an understatement!) Clear skies! Thomas Jensen, Denmark...
Woweee! I had been there VERY often, i think, had such a beast been near me! The views must be absolutely incredible. Clear skies! Thomas, Denmark ... ...

Hi, I have developed absorption plastic filters that employ exoctic organic dyes that often mimic interference filters. These filters are about .005"...
I have posted a picture of the refractor OTA handle I made in the photo folder Richwood. IMO a handle like this makes for much more secure handling of the ...
Larry Stop teasing us and tell us how good the 8" D&G is! We want to hear about a real telescope! Not these wimpy little 6-inchers! ;-) Regards Chris.B (6"...
Hi Chris, I just finished a review of the D&G that I am going to send to "Cloudy Nights" later today. It is a bit longish but gives a good overview of my ...
... Hi Rich, Excellent job and I agree completely with the utility of your handle. It does, however, assume that you store your refractor with tube rings and...
Milt; Fortunately for me both the standard dimension TEC 140 Scopeguard case and the factory included as standard case for my Stellarvue 102 ED APO have room...
... I would like to see AP offer a case with more room for rings and dovetail bars. AP said a long time ago that there were too many different ring and bar...

... The new AP 160 has a sliding dew shield. My way of lifting the OTA out of the box wouldn't work with this new dew shield (I don't think). Maybe putting...

No need for a custom case. For my AP130 I leave my rings on with a 8" sliding bar on the bottom and an AP plate that accepts a dove tail on the top. The top...
Aren't you left with very little foam in the places where you made the cuts? Wouldn't a hard shock now be more easily transmitted to the OTA via the rings...

... Company 7 made a custom case for my 155 sans rings. The top is not hinged, but comes off completely and the sides of the case are designed to spring out...
... All good ideas, everyone - thanks! I take the care and preservation of these scopes very seriously, especially since the oil-spaced A-P's now seem...
Milt; How long is the AP 130/8 with the dew shield attached? SKB has some inexpensive golf bag cases about 4' long that might well do the job once foam lined....
... Rich, with the dew shield in the normal viewing position the 130 is close to 48" already including the MaxBright that I would like to leave on it. However...
Milt; Another OTA handling aid is in the Jan 2006 S&T in the annual hot products section on page 106. It is called a scope-tote and is available through this...
Not an issue as the OTA still rests on the foam. The bottom of the rings or the dove tail do not touch the bottom of the box. I just sliced out two channels...
