Dang, that's not a bad price for a Rumak style. It weights 20lbs.

It's well made, the views are very nice through it. I will be keeping mine!

I have the AstroTech version, and it's keep its collimation perfectly, provides delightful razor sharp views with zero image shift, and it's binoviewer friendly.
While it will do well on a GEM, I've used mine on an Ioptron Mini-Tower to good effect. It's too heavy for mounts like the NexStar SE.
Sturdy, well made, mine weighs in at a bit more than 14 lbs, sans finder, and using an AstroZap dewshield.
My only complaint about the design is that it requires a bit of care mounting and dismounting. There isn't really anything to grab ahold of during the process. At 0300 it requires a bit of thought and care to put away for the night.

I love the fact that it comes with a dew shield.
What size is the central obstruction?
Any idea who actually manufactures it.

SteveW,
It is a clone of the AT6M with an added dew shield.
It is made by Bosma.
38% by diameter, 14.4% by area

Thirty eight percent diameter????? Yikes i thought it was f/15, i guess thats the f/12 difference. Id prefer the smaller co and longer f ratio.

Steve. The ioptron version also comes with a dual focuser which is the only one that does, and is a very good focuser indeed.. ofcourse the alluminuim screw on dew sheild is a plus also. Overall its a fine OTA and when cooled down properly shows more detail than my C8.
cheers.
Graham.

Thats quite impressive. Id have thought tge CO being that big would hamper contrast. Sometimes i reconsider for a meade etx125 but ive never been a fan of the name. the orion ota seems nice too. Any comparisons between the three?

Hi Pete, I just picked up a 5" Orion Mak-Cas and my initial impression is that it is better than an older C8 I have and nearly as good as my 6" Intes MK-63. Very nice scope and nice and little!

Mike, now you've opened the can-o-worms. LOL
I got my backside chewed for saying a mass produced scope can be as good. But, I suspect it can be as good as the standard Intes models anyway. An MCT deploys a few 'tricks' to correct for SA. If done correctly, it results in smooth optics and better than 1/4 wave correction even without aspheric correction. But, hey, that's me interpreting a star test, again.
When folks claim them to be better than a C8, though, that raises some eyebrows. Resolution should not be better and MTF should be about the same, so maybe folks need to be more specific in what they mean by better. I don't argue the point, I love the MCT design. It does get more use than any of my previous SCT and Dobs and does give very pleasing images. Some of that is the portability, the reminder is the views. I have yet to be left wanting, even at a smaller aperture.
So, the point is, an MCT can /approach/ refractor like performance and definitely inspire refractor like love especially if well corrected with very small aberrations. The Orion, in my view, meets this standard. I am sure the IOptron and others do as well...there is something about the design that allows it.

Or he's just got a *BLEEP* copy for his C8.

Well, not that I mind opening a can of worms, but will say thar I'm very new to observational astronomy and go by how everything looks to me... I only had the Orion out for about an hour and it was not side by side with either the C8 or the MK-63.
I just received another old Intes (MK-65) and as soon as we get a night that is clear I'll get all 4 scopes out and so a head-to-head and try to be more objective. I agree "better" is way to subjective to be vary meaningful.

Pete,
SLOW... Just got some clear nights and I'm hoping to get out soon. Biggest problem I have is not knowing how best to compare the 3 or 4 scopes in a way that is not very objective. I guess I'll look at some other reviews to see if I can come up with anything. I also need to pick up a couple of eyepices so I can keep the magnification comparable between the scopes. Since this tread was a question about a 150 iOptron Mak maybe I should start another. Mpre to come!

Europeans who is interested in a Bosma Mak atleast with similar specs: In France a 6" can be had for 590 euro, sometimes these Maks are one sale for around 350 euro. Bought from them once without problems, I am from Denmark.

There’s a shoot-out between a Celestron C8 XLT, an Intes MK67, and a Tak TSA 102 on AM. The review was just written 10.3.11. It’s a well-written and pretty extensive review from an observer’s point of view. The review concentrates on Jupiter and the details seen on that planet. The reviewer appears to be experienced and a dedicated observer living in California.
Bottom line: in average seeing he felt the MK67 was delivering a little more.
In above average seeing, he felt the Tak TSA 102 delivered the most details and could be pushed to (and take advantage of) higher power over the other two when seeing allowed.
