GT 71 or Others

#1

Post by astrographymc »


hi folks,

Currently I am using a Redcat 51 and an ES ED 127 mm APO Triplet. Now I want a focal length in between. I am thinking of WO GT 71, which is currently in my budget. I have an iOptron SGP and A Bresser EQ5 GOTO. Currently i am using a Sony a6400 and an ASI 533 is on the way. so,

1. is there any Flattener only (not reducer), that can be used with GT 71 ?

2. Can i use iOptron SGP as my travel rig with GT71 ?

3. are there any other scopes in this price range og GT71 ? please tell me so that I can think of that.

4. How about those built in flattener scopes?

I have both a GT71 and a Z61. I also have the SGP and a much larger Celestron AVX rig. The GT71 is a great scope that also comes with a flattener. The weight is about 6lb before adding flattener and camera. Once you add the trio, it may be too heavy for the SGP. The Z61 is similar in focal length and smaller and lighter and does better with the SGP. Either way you need a very heavy tripod for the weight.
