thanks for your reply with pic..fc 76dcu is f/7.5 and with 1.01 extender f/7.8. So i think it will be better for imaging.

Are FC 76 DCU & FOA 60 good for Deep Space Photography ?

Hi all,

Is there any equivalent of ASAIR Pro for the QHY cameras ? Thanks in advance.

hi ,

have anyone used the QHY294C Pro ?

1. What is it's  back focus distance? does any adapter (M42-M48) and spacer include in the box like the zwo 294 version for the backfocus maintenance? i will attach it to my GT81 .

2. does it come with the power adapter ?

3. any user review of this camera?

Are there any "only flattener (not reducer)" that can be used with WO GT81? I want to use the focal length 478mm for the scope , not the reduced 382mm with their dedicated reducer flattener Flat 6AIII. I have come across these two followings. Can those be used with the scope?

1. Ho Tech SCA  Field Flattener 2"

2. TSFLAT 2  Universal flattener 

If those can be used, how about the backfocus? Will I need any extension ring? Have anyone used this ?
Please help.

then why the same 80mm FPL 55 is expensive than FPL 53?

one of my friends is a little bit confused in between these scopes -

1.  TS-Optics PHOTOLINE 80mm f/6 FPL53 Triplet APO - 480 mm

2. TS-Optics CF-APO 90 mm f/6 FPL55 Triplet APO Refractor - 540 mm

which will be better for imaging ? not for visual.

Which glass is better for imaging , FPL 53 or FPL 55 ? Have anyone used either of the scopes? what is the performance of each of them? 

Please suggest.

I have a redcat 51 which is my travel scope. Now i want a refractor triplet in a range 70-80mm. But i don't want to loose the focal length by using reducer [removed word] flattener. In india not many  branded scopes are available. I have to choose in between WO / TS Photoline / Explore Scientific /Sky watcher  . WO triplet scopes have problem that they use their own reducer [removed word] flattener in GT series. So the focal length will be decreased, which I don't want. Please advise.

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?

Hi,
I am Mainak from Kolkata, India. I am doing Astrophotography from 2019.
I have an ES ED 127 mm scope and a Redcat 51 for Astrophotographic purpose. Also I have an ES 12 inch Truss Tube Dobsonian for visual use. I live in a Bortle 3 zone. So Astronomy & Photography is a very good option here.
Great to be here with all of u to learn more and more about Astronomy & Astrophotography . Thanks to all.
