I also have a TEC 200 Mak and definitely love to have that case.

Beautiful scope, I am sure you will enjoy it. And the 29 Arc Minute Double cluster will fit very nicely in it

I've had the need to scratch my Mak itch lately as well DC.
I think you'll enjoy the TEC, and be able to get the most out of it if observatory housed. Don't be alarmed if the focuser might have become disengaged during shipment(likely rare, but it has happened to others). It's an easy fix for you or Yuri.
Managed to pick up a super rare LOMO 203 MCT a couple of years ago. A quick analysis indicated it could never have been collimated because one primary collimation screw required replacement with a longer one to even line up the baffle to the secondary...then never really used it(apparently wasn't itching that hard back then).
Pulled it out and disassembled a couple of weeks ago to consider the possibility of cooling upgrades. Found the full length baffle tube cocked sideways. Clean, polish, reattach, relube, (and reinstall the factory collimation screw) etc....and the thing really rocks! IIRC the history page from TEC's website correctly, it was LOMO that Yuri did some of his first work with in the US. Both LOMO and TEC are pretty darn good bets on superb optics (and a bit in common when it comes to design cues too).
Split the Trap at med mag under Pickering 5-6 skies....yours will too. Enjoy!

Mark: please post some pictures of that LOMO it would be fun to see it! Does it have an integrated fork mount or is it an OTA?
Dave: I know what Mark is talking about because my focuser did become disengaged once after shipment. If it ever happens its a trivial fix that Yuri emailed me how to do and it takes 10 mins max.
Bob
PS Some colleagues of mine visited LOMO a few years ago as they're one of the few companies capable of handling the fabrication of the Thirty Meter Telescope's mirror segments (mass production is needed, basically). I was told their huge facility resembles a car factory. They are such a big industrial outfit I'm a little surprised they do optics for the small amateur astronomy market too.

Hello Dave,
When you post the info pertaining to the case that comes with your TEC 200 Mak, would you mind posting it on this forum message? I also have this same scope and I'm interesting in that case.
By the way, I love my TEC Mak and I'm confident you will as well.
I really like using it with my binoviewers.

Bob, all this talk of loose focusers.... 
I'm bringing this baby home in my car, not entrusting it to those 'shipping' companies. Should be fine......

Your Mak-Newt is f/4. My new Mak-Cass is f/15.5 - - different beasts entirely.
I have an 80mm (3.1") William Optics Fluorite doublet, f/6.9 which will be the 'finder' as well as a scope that can get all 4 degrees of both halves of the Veil in one view....
Dave
I know. Perhaps we should compare at WSP?

Only have a pic of the skewed baffle to primary attachment right now. More later.

Keith how does your 9.25 SCT compare to the TEC MAC?-Perhaps the same amount of detail only the MAK is a bit sharper with more contrast?
Congrats on the Mak Dave, you must have acted pretty fast in buying it. It went pending in less than 24 hours. Your 15.5 will be the forth that I know of in the GTA.

Dave,
When my TEC 250 was shipped, it had a shipping screw to keep the back end "happy" in transit. A call to Yuri could confirm if your new baby also has this, and what size should you need to stop by a hardware store.
Congratulations! You're going to like the new toy.

I don't want to hijack Dave's thread, so will post pics of the LOMO 203 by starting another.

Hi Moon, I have only compared the TEC 200 and C9.25 on one occasion and that was under suboptimal seeing conditions. On this night the views through through the Mak were definitely of higher contrast and much preferred.
Now if I could just get my hands on a TEC 250 Mak!

Safe arrival home of scope and case by 5:30 pm today (Saturday). I asked the seller about the case and he told me that the company has been out of business for several years...... I'm pretty tired from the trip and will not bother further with the new scope until tomorrow morning. I'll get some pics up here.

Here is the info pertaining to the transportation screw from the manual:
Transportation screw, 6-32, 1.0" long.
Please remove it before using telescope and close the hole with 8-32 screw included. Transportation screw is needed for shipping only!
Best regards,
Keith

Here is the info pertaining to the transportation screw from the manual:
If youneed to send the scope by any carrier, put micrometer in the position near 10 as shown and screw the 6-32 thumbscrew in. If you do not have original one - use same size 1.0"~1.2" long screw.
Transportation screw, 6-32, 1.0" long.
