I just posted a synopsis of my discussion regarding the A-P 140 in the "APitis" thread.

 

Bottom line: At NEAF 2010, I asked Roland specifically about the 140 (I was also on that list, too) and he shook his head, "No".  He suggested that I buy a TEC 140 and that is what I did. 

 

Sorry,

 

Ron

An excellent suggestion.

Whoops! I just heard from Roland, correcting my earlier remarks about the origin of the 140. He says it was never about cutting down 155mm lenses, but was a unique design intended to be at that size. He says it was impossible to get more of the glasses needed to produce this telescope in the needed quality, and so this particular scope is defunct and will not be offered again. That fixes me for posting vaguely-recalled rumors.

It's very tempting, especially as oil spaced- but the 130GT I have suits me better.  If the 140 had the 2.7" focuser id consider it more.  

 

Astrophysics is my favorite all around brand.  If you can afford it, hard to imagine you would be unhappy.

I owned an AP140 with the 4 inch focuser. Yes a lovely scope. I used it for imaging but did look through it. Very pinpoint and sharp stars.

It was certainly a great imaging scope. I used a 4 inch Tak flattener on it which worked fine. I also got the Quad TCC and used that with it too.

 

I only sold it because my name came up for an RHA. I sold my TEC180FL as well to fund the RHA. I don't regret the sale. The RHA has been my primary imaging scope for the last few years and I intend it to be in the future.

 

I did pick up an as new 130EDF GT a few weeks ago. Its a lot smaller and lighter. The 140 was reasonably large and solidly built.

 

I also have a CFF105 F6 FPL55 oiled triplet with 99.4% strehl in green and a 3.2 inch feather touch focuser. Superb, superb.

 

I plan to have the AP130GT operational shortly. Just waiting on the usual adapters for a new scope. I suspect the 130 will be a match for the 140 as I found the focal length of the 140 a bit odd in that not 100% widefield and not really long enough for longer focal length images.

 

I prefer a high quality decent aperture to do widefield imaging. Long focal length is best served with CDKs or Newts etc. The TEC180FL is a large scope, handleable though but pretty close to the limit. It needs a decent mount although I managed for a while using a Tak NJP mount but it sometimes did not work too well.

 

Greg.
