For those that prefer a black tube, there's the upcoming Orion 6in/ 150mm classical cassegrain w 58mm secondary:

Seems to be the same GSO-made scope sold also by Astronomics (AT) and TS and discussed at length here:

EDIT: Oh, I guess you mean that the AT version has a white tube. TS has a black tube as well.

One problem I have with these scopes is the short focal ratio. One reason the CO is 38%. What bothers be most is how fast the primary needs to be to hit F12. Assuming the hyperbolic secondary is 4x like all the CC scopes I know  assumes the primary needs to be F3. My Cave 12.5" Convertible primary is F5 so the total F-ratio is F20 and the CO percentage is much lower. F3 would mean a lot more coma to correct. We will see I guess.

38% more than the 33% mentioned and too high for this scope to be a planetary scope period.  The 8 inch may be slightly less when are they releasing that i wonder.

 

A 180mm sw is around 32% an obvious advantage.

 

The rule of thumb is 8 inches or above f15 can get close to 30% obstruction and DK's at f18-20 can go under this.

Takahashi cassegrain CN 212mm has f3.9 main mirror.

68mm second mirror so 32% obstruction and f12.

2544mm focal length and Zambuto like optical quality.

Can only hope these new ones can be close at 1000 usd.

Orion selling:

150mm $500 shipped USA

200mm $950 shipped USA.

That includes additional finderscope saddle for guidescope.

 

Here's link manual:  https://www.telescop...Cassegrains.pdf

 

dang cheap labor; one could buy Orion 8in CC and used Tak MT newt vs used CN212.

Thanks for the link. The instructions include collimation procedure. Mine was a tiny touch out. Easy to do with a cheshire.

Thanks for the info.  Maybe I'll eventually be able to try one out.

Hi Doug mc, The black looks really good!

 

When the seeing is good how high have you been able to push the magnification on the moon and are the images razor sharp?

Do have to use any extension rings with your TS binoviewers or eyepieces by themselves? Any other information would be greatly appreciated.

...and Zambuto like optical quality.

 

Do you have some interferometer tests to support that?

Everyone swears that the Mewlons have been figured by the light flutter of angel's wings, but Astro-Foren.de had tests of three different Mewlons, and none had the quality of the Intes Micro telescopes.   Until I see even one example of a model of scope that tests near perfect, I don't assume anything about them.

Those Tak's CN212 were like $4000 US to start werent they?

 

Even now, they go for $2000- $2500 US used, double the price of these GSO offerrings.

 

Not quite a fair comparison.

You may have a point, but a Mewlon 210 seems considerably more portable than a 8” Intes Mak Cass. I think of a Mewlon 210 as being similar to an 8” SCT in terms of portability. I don’t think the same of the Intes. So the Tak has that going for it.

Never owned or used either one, so not biased.

Very interesting, he describes it as an astrograph. It even has a Losmandy dovetail on bottom with a Vixen rail on top, and two finder shoes so you can have a finder and guide scope. Ideal for lunar and planetary photography or even brighter DSO using the newer highly sensitive cameras. Sort of like an alternative to a RC, but slower to get the CO% low enough for visual. Of course slower makes it less appealing for DSO AP. I could see a niche for this for lunar/planetary imaging I suppose, or possibly as an alternative to a 8” SCT. I mean if you hate dew and image shift it could be a good option instead of sct just for visual, although the SCT is considerably more portable and about the same price.

All I can figure is that they ran into some very serious QC issues during late phase development and early production. Either that or supply side issues. The hold-up is obviously at the production facility as the ship dates have been pushed back (and back, and back) by the various branding vendors of these instruments (Astronomics, Orion, Agena, etc.). It’s certainly not a trade/tariff issue as they are coming out of Taiwan and not PRC. I’m sure glad that I reconsidered, cancelled my order, and got my money back before the end of last year (Astronomics). Good luck to all you fine folks who have stuck with it.

Luckily that i bought SW 7" Mak last year, not a bad scope, giving me amazing moon shots and not bad planetary too, so i don't think i need any Mak now, rather than just buying another type of reflector so i can use it mainly or only for planetary, not SCT.

 

I may recommend those here for anyone who would like to start and looking for good scope for solar system maybe, a Mak also has its place in AP, not only refractors or SCT or Newt, but i will see how far this Mak thing will go.

Just ordered mine this week. Told it's expected to ship by the end of the month.

 

Did my homework, and hope to be at least as excited the day after first light as the day before!

welcome to cn, 

congrats, look forward to your pics and feedback.

 

not sure why orion is not offering a white tube version like agena.

while AT no longer has link to 200mm cc?
