Review of Mak 150

Hi all,
No time to do proper testing of Mak 150, but here are the results:
Straight out of air-con room, and when condensation just cleared, Jupiter GRS is easily focused with 10mm Radian. Note that the Mak has not reached thermal equilibrium. The star test shows thermal currents.
Overall, very high contrast OTA. at 180x, there is very little sign of image breakdown.
I have not seen through a C6 before, so I cannot compare, therefore take my comments with a pinch of salt.
Thanks.

Hi,
Hope to see a more detail review on this scope when you had more time.
Have a nice day.

Oh, interested in the scope?
I will try to test it throughly as this is the scope that I hope to use it as a travelling visual scope. If it turns out to be ideal, I will equip the scope fully with solar filter, dew heater,.....
Note that I used the scopestuff adapter to turn the visual back into 2". Image shift is obvious at 180x but it is not that much to make critical focusing difficult. It is about as heavy as a C8, so porta mount is not able to handle it. Next time I will use EQ-6. The focuser is buttery smooth, which is useful for critical focusing. The scope smells of paint when it arrives, so make sure air it to let the smell disperse.

Oh, I got it from Robin (McGill). Yes, the 180 is a super tempting instrument. A big jump from 150 (in terms of contrast and WEIGHT and PRICE). Considering portability issues, I decided on the 150.
GPD could barely take the weight of Mak 180, HEQ-5 is probably the minimum to take Mak 180. Hehehe

probably the best way to overcome image shift in any moving primary scope.

Robin still in business?? I sms him on one of the items and he never even reply.
Thought they close already.

probably he misplaced your sms. What item do you want? I can ask him for you.

Now I don't need it already. Actually wanted to ask him about the Vixen 5" reflector that you have. Wanted to get that as a grab and go, but since he never reply, I bought other things already..
