Quote:Have a great vacation! Be sure to surround yourself with protective foam so nothing happens to you on vacation! We need this scope!I was out observing last night with my MCT 150 at F12 and realized that a 6" F/8 is going to be the perfect compromise for a lot of folks, and I am even happy with a 42mm finder eyepiece in the MCT, so I'll be happy with this one. I also just found out I apparently stopped being stupid about taxes for 20 some years and filed just in time to see that when this scope gets here, I'll have the funds immediately for it! I am setting aside $4000 for this new scope and the lx80 provided the lx80 comes out and is not riddled with issues, in which case, I think I'll have to go GEM completely, so let's hope it has the big 3" or 2.5" rotatable focuser like the AT or CT scopes or that SV 2.5" rotatable or equivalent.Any chance of doing a removable section so you can make it BV friendly with a little removal of a section and moving the focuser? I'm going to venture a guess as to a NO on that to keep in price wishes, but would still be cool.

Quote:Joe, I have that SV focuser on the AT152, its nice, not a FT but not far off, I think the FT would handle a wee bit more pounds off the back at zenith but am please with it so far. This scope sounds like its gonna be really nice and I am already listing my M703 for sale to help pay for this puppy .I do give up the compactness of the MCT but I will just have to live with that and eat my wheaties!Jim
Quote:Markus, the 140mm FPL53 doublet, please! Go long, F8 or F9. This is a visual instrument. At F7 the imagers will never stop with the TEC140 comparisons. Let them buy a triplet! At that price range this is an instrument I want.Dave
"your signature is too long. Please use the back button to edit your signature" A scourge of equipment unpopular to most, but fun for me!
Quote:Would definitely not be interested at all at F/8, or F/9. Maybe at F/7, but would have liked to see an F/6 or F/7, 6" doublet that performed like an F/12 or F/15 achro. I guess I am in the major minority. Particularly the F/6. Short and stubby, but performs like a behemoth F/12 or 15. Fast enough to get wide, but still could use a semi-apo filter and give decent planetary.

Quote:Hi Everybodytoday things change again :-)The Glas prices I posted yesterday have been the guess of my optical designer using catalouge prices. Today I got the manufactur estimation of the expensive 6"F/8 doublet and it looks like we c an do that too , estimated price for the expensive 6"F/8 doublet between 3500 and 3900 $so whats now ???? 140 mm F/7 ? F/8 ? or a 6"F/8 ? or both ?The european price will be about equal in Euro as it is in USA in US $ thanks to customs and our crazy 19% VAT, so US Price 3,500 $ means European price Euro 3,500 incl. VATnow we have to many choiceswe run a vote or we think about 140 and 152 ?
Quote:MY vote goes to what ever is going to be visually a better performer!!!!

Quote:I've been asking for a 6in. doublet for the last 3 years, 140mm is to close to all the 127-130mm scopes out there right now. Just my opinion.
Quote:2, personaly I ote for the 140/7 FPL 53 in any case and the 152/8 too, becasue there is a big market for the 152 for those who want to replace here achromat and by a simple tube adapter this is a very easy tak for anybody.

Quote:A 140 mm F/7 or F/8 FPL53 doublet Apo optical tube can be done incl. 2.5" focuser, set of rings, finder shoe, case for around $ 3,500 retail...if we order minimum 300 pc.I have a personal feeling the 140 mm should be the way to go and at this price point, I believe we can sell more then 300 pc

Quote:I was quite interested in this project right up until it took a turn toward a 140 mm aperture. I am interested in a 6" aperture ED scope with a focal ratio around f/9, to allow a little extra focal length for better correction...I am not interested in losing virtually half an inch of aperture to settle on a 140. If I'd wanted a 140, I'd already have bought a TEC 140... So if this continues to drift off course from it's original direction, toward a 140 instead, you can count me out.
