That is why I love high end refractor optics. You look through them and just love it. Want more power, seeing permitting, and you just use a stronger eyepiece. You want to admire the difraction patterns you can without anything in the way. A high end TMB is still on the buckett list. The 6" F8 AP is nice, but the optics are nothing compared to the latest ED triplet scopes that come out of Russia or from AP. The older long focus achromats are very nice, but once again if you want image scale you need at least 4" or more and a substantial mount to hold them steady. That is what I like about the Telementor or the Zeiss APQ. If you have the cash jump straight to the Zeiss APQ and skip over the Zeiss AS100. There is one TMB 4" scope that I have heard will outperform the Zeiss APQ100. I would really love to try both scopes at the same time. These are scopes that require very little cool down time and perform like no other. The perfect grab and go scope. But as usual. paradise has its price

Reflectors do have some issue for sure. My 6" F8 doesn't go out of collimation, but it is a machined cell wot push pull screws. They are more apt to tube currents and cool down.
You really do get to see a lot of detail in Jupiter's cloud belts. Faint fuzzies are not so faint fuzzies.. But they do need more cool down and set up. Tube currents are an issue, but that can be dealt with. Yes they are more fiddly.
Terra, I like the reflection comment.. Heard that one once before. Very funny. SCT's are a nightmare to cool down. BIG nightmare for an 11". Makes Reflector cool down child's play. Needless to say, my C11 only goes out once every month or so. The mount for my 6" F8 lives outside, so I just take the tube out and put it on the mount.
Small refractors are easy to use. That is for sure.

There is always that question of quality optics. Modern lens grinding and polishing methods have really got to state of the art. My question is??? Are the optics of classic telescopes, refractor or reflector, as good, better or the equal of todays modern optics. Guess we can throw in hand crafted optics in this mix

WOW Scott!!
Beautiful scope! Back in 1976 I saw this same type of scope on the TV series Space:1999 and have wondered about those extension tubes ever since. It seemed hard to believe that someone would place a mirror extended on shafts like that.
Does it hold colimation well?
In the series, the scope belonged to Professor Victor Bergman. He uses it in an episode called "Another Time, Another Place". I will have to look at that episode to see if the mirror cover is removed when he uses it.
Enjoy that scope!
Cliff

That is my favorite episode of year 1 SPACE1999. You will also see it on a few year 2 episodes, they use it as a laser.

You must mean the TMB 100/800. You will have your chance to compare these two scopes when we have the Central MA refractor party. See the Refractor Forum thread on this.

I emailed him yesterday morning when I first saw it, just a few hours after the add went up and never got a response. Actually my email was about the OTA with solar screens. Never heard a word.

The shot of the tube in the case looks bent because the dew cap is on at an angle. Cover up the dew cap with your finger and the tube looks straight. Or at least to me it does.

I've heard good things about the AS 100 lens but color is noted and somewhat expected as I believe it is considered to be a super-achro or something like that. Was that why you were disappointed?

Good catch, looks that way to me also. Plus the subsequent photos of the tube look strait.

The views were not as good as I was hoping. Views were soft and not sharp like I expected. Maybe I had a bad lens. Hard to believe from Zeiss. I had a few other triplets at the time and they were much sharper. Maybe not a fair comparison, but considering the AS100 cost me more I felt that if I had a scope that cost less outperforming the AS100 that it was not worth keeping.

Re: Ebay ads [Re: starman876]

Heads up everyone!

The Ebay scams involving high end gear offered at a (relatively) cheap price have moved up in sophistication. The scammers are now making use of Java in their Ebay ad pages to redirect your browser from the genuine ad page to a similar looking page on a phishing site, which if you then click on 'report item' or other links seeks to obtain your login details. See for example the discussion on the Audio Karma forum.

So, in the words of Sergeant Esterhaus "Let's be careful out there!"
