The 180 f7 was $8,200 in 1995. I don't know what the market price would be.

I can't think of any that have changed hands. There were only a few made.

No disrespect intended, for I am a big fan of A-P, but with a TM Back 7" f/8 apo

selling for $12K and the 8" f/8 selling for about 20K (I think?), I can't

understand why people will pay the prices they do for the larger AP apo's on the

used market - especially after reading the reviews and first hand comments from

users of the TMB scopes.



Anyway... Roland, I know you have only so much hair to give to your company

(g>), but have you ever considered trying one of the new hair-growing products

on the market and then starting another production run of the 180 EDF :-)))?

#1958 Mar 3, 2001

Hi Larry,



The price for a used AP 7/7 is hard to believe. I'm not

sure why someone would pay the price someone mentioned

recently. However, the finish and design of the machanical

parts of the APs is, IMO, much nicer than the TMBs.

#1959 Mar 3, 2001

Hi Rich,



Agreed. The AP products are works of art as well as research grade

instruments. They also represent the best trade off in weight vs.

strength. - Besides, Tom Back doesn't even have an asteroid named

after him g>.



I'd rather have an AP... and I'd pay a premium for one, but not twice

the price. I love AP products, but even love has its price...

As an owner of a TMB 105/650 and hopefully soon to be owner of an AP 155, I

must agree with you regarding the finish of the AP mechanical parts as well

as the tube finish. As for the design of the TMB mechanical parts, they are

certainly world class, robust and IMO, a bit "overbuilt". The focusser on my

TMB is a joy to use. It is smooth and precise. The only thing I would change

would be the weight and the finish. The rings are another story altogether.

I have modified mine by milling off 1/8" in thickness and had them polished

with a #4 scotch bright finish. My opinion and subsequent modifications of

my TMB rings has stirred quite the debate on the TMB eGroup.



The optics however, are first rate.



Thomas Back is excellent in terms of customer service and satisfaction. When

the dewshield lock mechanism failed and proceeded to scratch the finish on

my tube assembly, without question or hesitation he agreed to replace it.

TMB sells a 175 f6 for $11,990.00 and a 180 /1400 (not sure anout the f

ratio) for the same price.

Hi Roland,

Seriously, I believe they were $8200.00 in 1995.



I would be willing to pay between 15K and 20K hands down!

enough profit margin?

#1966 Mar 3, 2001

Roland,

I can't directly answer this, but your question sounds encouraging?

If you did decide to manufacture a larger refractor, the 7" is

only slightly larger than what is now in your product line.

Why not a 200 mm or 225 mm F-8 or F-9?

This would sure give the 12.5" R.C.'s a run for their money!

I remember your reasons for stopping production of the larger

refractors, but all of them really came down to money.

Is there now any improvement in the glass products available,

or any new glass products that didn't exist back when production

ceased on the 7's?

The amateur community has changed slightly in that there is either

a willingness to spend much more or the ability to spend much more,

or probably both.

I doubt that you'd have any problems filling up a production run

or two!

Colt,

You are right, there is a market out there for high-end scopes.



For example, concerning RCOS scopes, The price range for RC's is 10K for a

10" to 40K for a 20" and they are selling!



I think the market for a new 7" f/7 is out there!



OTOH, I don't want Roland losing any more years to Astronomy! :-)))))))

I don't know about that. Why is everyone tripping over themselves to buy a

cheap Chinese achromat? Anyway, the market for high priced refractors may

vanish if the stock market does not recover soon.

Probably similar, if it's done right. So should AP forget about 4", 5" and 6"

scopes and concentrate on larger instruments?

My AP 180EDT f/9 was $5995 in 1996. How much more

would a 180mn f/9 or f/8 be using FPL53 only five years later?

Unless someone is just taking the view of all the traffic will bear.



I do like the idea of making more of the AP 206EDF or maybe

something even larger.

Why do you think some people have been buying the

longer focal ratio TMBs? Maybe they are AP customers

who didn't see a chance of AP ever making longer scopes?



Rich

#1983 Mar 3, 2001

Does TMB offer a 7" f/7?

I thought they were buying the longer focal length because this was the only

selections offered!

Yes that's a good reason. F/7 is the right compromise for both imagers and

visual observers.

NO! We need wide-field imaging instruments too.

Bobby Middleton



----------------------------

#1986 Mar 3, 2001

Roland,

I would want F-8 or F-9 for imaging. Yes, it's slow, but

that's why you make the 1200.

F-9 hasn't slowed down the R.C. market, and F-9 is only slow

in the film sense of slow. Typical long exposures in ccd imaging are

10 minutes. So someone accustomed to 10 minute exposures might have to

go what - maybe 12 to 15 minutes. Hardly a problem for the AP1200.

I would want the image scale of F-8 to F-9.



With your focal reducer it would become a faster instrument with

a smaller image scale, and wider field of view.

2 scopes in one.



A 200 mm instrument would be a nice addition to your product line.

It would sell successfully in probably one small production run per year.

The 1200 is more than an adequate mount, and I'd like my name on the first

list please.

I personally wouldn't be as thrilled about buying a 7" when the 6" exists

all day long. Now an unobstructed well corrected 8" refractor from A.P. is a

whole new ball game. 10" would be even better but I think this isn't

practical. (easy for me to say)

I would have selected a F-8-9 AP 8" refractor over a F-9 12.5" R.C. had the

choice existed.

Maybe that is the answer. We need to get Mr. Greenspan into astronomy and

onto one of these AP waiting lists. That would probably put him more "in

I guess I will have to get on that 1200GTO list in addition to the 7" f/?

I am with Bobby on this one, f/7 please. I figure by now that I am about #

8 on the waiting list:-)



Roland, you have been floating scope ideas on the APML group. Is this

scope the answer to your quest for high resolution imaging of deep sky?

Are you still considering the aspheric Maksutov?

I'm still leaning toward mirror based scopes for imaging vs. larger

refractors. Mirror scopes are easier to make in large sizes and will be

smaller and lighter. I prefer Maks over any other design. There are so many

possibilities with Maks.

Ditto. In the $12 - 15K price range, put me on the list too.



But you know, your question about the downturn in the market is a good one. So

you need make only one 180 mm f/7... for me, because the rest of the guys ahead

I'm getting sick of seeing that "I" word. Isn't anyone interested

anymore in observing? Can't money be made selling at least

a few telescopes optimized for visual use?



I was using my AP 155EDFS last night at one of our club's

public star parties. The point of focus is really small. And I

wouldn't mind a longer tube at all. I would just like a choice,

from AP. Yes, I could buy a Tak but I would rather not. I could

buy a TMB, but what I've seen isn't something I would want.



I think the AP 130mm f/6 and 155mm f/7 are outstanding and

I want them both, but I also want longer focal ratio refractors.



Rich

#1993 Mar 3, 2001

Roland,

Well, this pretty much says it all.

I am very impressed by the image quality of the 10" Maks.

It is a superb instrument, but F-14.6 is out of the question slow

for us imager types.

So do you intend making a 10" + instrument in the F-7,8,9 range?

Just curious. The unobstructed design I would order in a second.

Roland,



You took the words right out of my mouth. I prefer mirrors for

larger sized optics too... not only because of the expense of

refractors vs. mirrors, but I need a scope for:



1) visual

2) imaging

3) spectroscopy



and not necessarily in that order. I would only use mirrors for

spectroscopy. The BK7 glass in the corrector plate of your M-C will

allow almost all of the light through and so it can be used

successfully for spectroscopy.



If I had my pick of any scope that you could make, I'd take a 10 or

12 inch M-C in a native f/8. So, while I am already on the list for

such a potential instrument, put me down a second one, for in ten

years time I could sell the second one on e-bay for $75,000 at least.

I'm sorry. I thought without saying refractor that unobstructed was enough

I think if you offered another run of the 180mm EDF's and offered a choice

of either f/7 or f/9 the run(s) would sell out very quickly. By offering

both focal ratio's both the imagers and planetary nuts like Rich N. and

myself would be very happy.



To get the process going Rich and I have decided to denote our hair to

Roland. Mine is a bit more gray then Rich's though ;-). Now we need some

volunteers from the imaging folks to denote their hair as well...

A 206mm f/8 would be very nice. Or, a larger aperture would

be outstanding. It would be good if it could still be used on

a 1200 mount for visual work.

but they don't do wide field well



Maks can be optimized for wide field as well as high f ratio narrow

field, do you remember 12" Astromak? it covered 4x5 format had an f

ratio of about 5 with 50% secondary, not for visual but simply superb

for wide field imaging.

More recently Ceravolo has been experimenting with similar concepts,

I seem to remember an 8" MN of about f/6 optimized for imaging on 4x5

format.

The only reason that you do not see wide field Maks is the lack of

demand.

Roland-



No, in my opinion. The money is only part of the equation. The physical

size of the smaller instruments make them particularly suitable for a

night in the field, whether for photographic or direct visual use.

I am waiting to see what comes of the plans for the 8" Mak. Here again,

size is a factor.

I agree 100% Roland. I wouldn't even consider making another batch of

7/7's. I mean really..... how many more images of M42 do we

need? :-D

Hi John,



Glad to see you haven't given in to temptation ($40K). ;-)

At least you know how to use a 7/7 to take a real photo

of M42.



John Gleason's astrophotos are fine art.

Don't worry about the value of your 180 mm EDF, John. Just to show

you my heart is in the right place, I'll give you $15K American for

it right now - cash, sight unseen - even though I realize that a

potential new run of 7" f/7's will lower the value of your baby g>.

Sssh! If Roland put up Dutch auctions for each run of his scopes they would

only go to the very rich -- rather than the quick and patient. Then there

would be the speculators...



Regarding this thread, I went for the 10" Maksutov-Cassegrain and am not

interested in paying more for a smaller diameter. Its not that I don't like

refractors. I'm very happy with a 130 f/8 that I was lucky enough to get.



For the 7-8" size I think an 8" f/14.6 Maksutov-Cassegrain would be what

would excite me.

Good news Larry! Your lucky day(or night). I'll give you first right of

refusal when I put it up for sale. After all, it is just a 7" telescope.

Any owner of a 12.5" RCOS will tell you that. :-D

The 10" Astro-Physics Maksutov-Cassegrain comes with an aluminum dew shield.

The recommendation is to place the Kendrick dew heater 1/3 of the shield

lenght away from the corrector. That prevents uneven heating of the

corrector. Does that help?

I would prefer an 9"-10" F/8 or F/9 Mak.-Cas. in a light-weight

carbon-fibre tube. I don't want to get another mount as the AP600E is

just the right size for me to transport each and every observing

(CCD) session.
