Has any one used the Orion 150mm Mak-Cass yet? I am looking at it in the new Cat. And am thinking about getting one. I know their 127mm is a good scope but I want a Bigger Mak-Cass.

So do I. Is this new Cat the same scope that ST reviewed in April 1999 issue ?

I'm pretty sure that S&T didn't review this scope in 1999 as this is a brand new product from Synta.

Yes. It was 6 years ago and Orion stopped to sale this scope for a while. And after Synta bought Celestron, I thought Orion will return to the russian optics? JMHO.

S&T tested two Russian 6" Maks made by Intes. One was the 6" Mak-Cass, the other was the 6" f/6 Mak Newtonian.
No Synta.

I received mine today. I owned a 127 a few years ago and liked it enough to try the 150. It looks as though I will be waiting until the coming weekend to get a chance to try it out, the weather is horrible here in Maine. I will let you know how it performs once I get it out for a trial.

Well, no review, but some looks through one. Try this thread.

It's the same scope as the Orion.

Well it turned out to be clear tonight so I got the scope out for a test. Jupiter was too low in the sky to view well so I had to go with the double-double in Lyra as my primary test subject. I was able to use Jupiter to check image shift though. At 450x the shift was about 1/2 diameter of the planet. I'm sure someone else can figure out the math behind that and what it really means but for me it was just my observation. The double-double split very nicely at 200x but I could tell that it would be a lot cleaner if I adjusted the collimation. I started that process with some success but by 11pm the mosquitoes were so fierce that I had to pack it in for the night. At this point I find the scope to be very similar to the Orion 127 Mak I had before with the benefit of more aperture. I plan on doing a side by side comparison with my Meade 127ED/APO once the collimation is to my liking and will make a report of my findings.

The image shift you see is very respectable! Only 15 to 20 arc seconds, which is a small amount.
A friend of mine bought a Sky-Watcher 150 Mak in May. His was also a bit out of collimation. He tweaked it and it delivered excellent images afterward. It's a good scope. The interior of the primary baffle tube seemed a little shiny (at least, in my friend's sample). Apart from that and the initial collimation, no problems.

Have fun with the 150!


Clive.

Cool, thanks for that. I think someone switched my bug spray with mosquito pheromones. It just couldn't cut it.

Thanks for the info guys. I think i'll just get the Meade AR5 instead. I have the LXD 55 mount and it will hold the AR 5 better then the 150 Mak.

I seem to be spending far too much time looking up the used equipment sections at retailers. Kendrick's has a Skywatcher 150 Mak-Cass (same as Orion - all Synta) in its used scope section. The price has just been reduced to $650 Canadian or I *think* $520 American. This includes a few accessories. I believe this is atleast $200 Canadian less than a new Skywatcher.

Just thought I'd post for anyone who's interested. As usual, I expect any buyer to pay my 15% finder's fee! :)

I can split the Double Double in Lyra at 100X with my SN8 scope. Guess I won't be needing a Mak-Cass from Orion.

That's nice, I'm very happy for you. After collimating the scope tonight 100x splits nicely now. I was pleased to find that the double double looks great at 450x in this scope too. I did not expect it to hold up at that magnification.
