Well, I found part of the problem in my 70mm Prismatic Achro Meade. The baffle hole in the center of the tube is not in the center! That is, the hole in the...
In most refractors the baffles are simply a friction fit in the tube assembly so easy to move or remove entirely. I have never tried disassembly of a spotting...
BTW have you tried contacting Meade tech support to see if a repair is available under warranty? This is pretty obviously a defective product even if well...
No, it'll come out and the prismatic is a reference to these violet-red spurs 180 degrees on the image that rotates with the tube. I'm just trying to remember...
Baffle position and hole size is pretty flexible and is dependent on the size of the fully illuminated field diameter wanted. In fact the TV scopes have no...
Because the telescope manufactures don't want us to know some of their secrets, they provide little information about the Optical Tube Assembley (OTA) and its...
James; If a vendor is going to baffle a scope so that what is advertised as a 150mm actually is effectively about a 130mm then to me that is false advertising....
My Japanese 60mm is sleeved for .096", but will take the 1.125" in lense. It gives a pretty picture of its age. Thank you for making me think about baffles....
... Here are a couple of little programs I wrote that can help. One gives you the baffle opening diameter needed at a specified position and the other gives...
I know that a lot of Japanese optical companies used to have symbols they used on equipment such as scopes and eyepieces that were sold under distributors...

Last night I had a chance to do a little observing. Of course, due to other constraints on my time :-\ and also an extreme heat wave that has hit the area...
I got the baffle out last night (just pressed in). Sure enough, decentered AND the inside hole of the baffle in spots had no black paint, just bright shiny...
Gentlemen; Here is why I joined your group. I am getting back into Astronomy after a 35yr. separation. I have several Planetarium programs along with Deep...
Hi Bink! A good place to start is an astronomy club if there are any in your area. That would give you a chance to look at other scopes and maybe test drive ...
Bink; Both the scopes you mentioned are equatorial mounted. Without motor drive installed I find that an altazimuth mount is a lot easier to use. I would...
Tried setting up a new album, didn't work. Think it wound up under Filar Micrometer. Was not easy to get photo, and Opera can get rather hinky with Yahoo. Let...
Very nice write up Wayne. It pretty much echo's my sentiments. I purchased a set of the originals back in 2003. The big push then was to have them for the...
... WG: Glad you enjoyed reading it, David. I posted the same report to Tmb-users naturally, but amazingly, it took TWO days for the report to appear there! ...
... Yes same here. I really only noticed it on the moon and then it was fairly obvious. The field is very dark with these eyepieces, much darker than anything...
I sold the two focal lengths (6, 8mm) that I owned simply because the field was /so/ dark and I couldn't see the field stop and thus it was very difficult to...
... WG: Jason, as you are using the telescope above, I might agree with you on that point, but a few added thoughts below--- ... WG: Actually, for the AFOV...
In the files section in the folder "Scott Walker" you will find a test report on the new reducer/field flattener from William Optics. It is called the FFIII....
No dear reader, this is not some strange off-topic post about pets, but it IS sort of a strange little story about some "birdie" that tweeted in my ear the...
... Wayne, I certainly understand your desire to complete your set. I had the same desire after getting two sets of the originals, as you did. The thing is,...
