A mate started my curiosity about the quality of Canon with planetaries. I did a test with Moon and Jupiter.
As they are many AVIs, with some options of filters and software for capture... I will publish as soon as they are ready.

As they will be many photos, and there is a limit of 500 Kb for each post ... I will do many posts here. Step by step !

For start point, the adpatation to use my Focal Extender 3x Explore Scientific 1.25" with Canon T3.
I didn't want disassembler all accessories, and I would like to test some filters. Therefore only the OAG is out of service.
Maybe an extensor of 35 mm together the focuser and Focal Extender isn't necessary. I believe that the focuser will have range. Although, in fact, I don't like my focuser positioned much out.


Well, these images are the first of my test.

GSO 305 mm - Canon T3 - Focal Extender 3x Explore Scientific

No filters- 25 % from 500 frames - BackyardEos 5x + AS!2 + Registax 6 + Photoshop CS3
FD: f/14 - Image Scale ~ 0.25"/px
150x in Photoshop - FD equivalent: f/21.4 - Image Scale ~ 0.16"/px


I know that is difficult compare two images from different days and seeing. But I was curious to see a comparison with ASI120MC.


I will publish more images, later.
