Stunning image. Can I ask how you sync the dithering etc with 3 cameras on same mount?

I use APT, a $20 software which has the only feature that is missing from any other capture software. I run 3 instances of it then under dithering I set 2 as clients and the other as server. Only server will be doing the dithering, the other two clients will wait after dithering is done and will take images simultaneously and process repeats

I was inspired to do this because my backyard is surrounded by trees  . In order to cheat time, even on a 2hr clear night I will get 6hours of data

OMG! what a setup. Interested to know the specs on the mount ie total weight limits and so..

Lovely M31,

I do the same, use APT to run one as server and the other as client. I would like to use SGP for the mosaic wizard but it doesn’t do synchronised dithering with multiple cameras.

Lovely M31,

The mount is Celestron CGX, total weight of the gear is about 46lbs. Since it is symmetrical, balance is not an issue. CGX per spec has a payload of 55lbs. I did try up to 52lbs and it was fine which is true to their claim that if you max it out it will still track fine..

I think APT  support mosaic now via import from CdC.

That is a lovely image of M31, have to say that its probably the best I have seen, looks really natural somehow

[kirkster501]

Love it.  Fabulous colours in there.

[ollypenrice]

Rich colours, tight stars, natural processing. This has to be a good one...

A very good image indeed, with warm colours. 30 hrs well spent. Did you process in Pixinsight? There is a tiny amount of ringing and a background structure in the full scale version that hint at deconvolution in PI.

This is the core of the M31 in negative HDR

Wow. There's a lot of structure in that core.

I think your image of Messier 31 compares to the one Robert Gendler produced many years ago. The hours you have put into producing this master piece, as paid off.

We don't usually get to see the Ha regions so clear and sharp as we do in this one. And the detail in the galaxy and spiral arms is quite astonishing.

 Now you're next project has to be M33?

[retret66]

yes, it is on my list, I did it last year but very few subs. With the tri-scope I will have more. I just have to wait until it reach 45 degreed above horizon because I am surrounded by trees in my backyard
