My first attempt at a mosaic, 2 panel......what a steep learning curve

I posted Sh2-63 earlier and finally got back to it as a mosaic to include Barnards galaxy, Mike did a fantastic version of this area some time ago.


Details below, click on image.

Not sure about this as yet, i have other versions, but I would like some suggestions if you think any changes or improvements.


Cheers

Hi George, the Preview is looking nice, but your Astrobin link is broken.

Cheers

Cool, nice field George:thumbsup:

Star colours seem to have all but disappeared? :question:

Loving all that dust though! :)

Love it. But as Andy said some star colours would just make it complete.

The colour data is probably there as its from a 16200 so not easily over exposed.

I imaged this area myself last week but I didn't get that large area of dust in it. I should see if a mosaic would pick it up as well.

See Mike Sidonio's version of this object. There is some Ha and O111 in Barnard's Galaxy as well.

Thanks Andy, I boosted the star colors a bit, I dont like them overly saturated :)

Thanks Greg, I have added some star colour, but as I said, I dont like too much. I did take some Ha, there is quite a bit in the area but I didnt like what it did to the image, maybe later.

That looks great and you've got some interesting colour shades in the dusty areas looks good.

A fabulous image.

Very cool George, very few images out there that frame these two babies in one shot :thumbsup: Nice work on the mozaic too. When I was planning my shot two years ago, it was the closest I have come to finally biting the bullet and trying a mozaic :scared:, to get almost this exact FOV :lol:....buuuut, hey, I capitulated and went for the fit'em (squeeze-em) both in one frame, approach :P

Nice job mate

Mike
PS. My shot of this field managed to make the cut for my wife's new astro wall (https://pbase.com/image/171893102/original) at our new place :lol: I never have any say in what images of mine she choses to print, she likes minimalism...

Excellent widefiled. Lot of detail and colour in the various structures. I have been trying to check Barnards and having difficulty seeing in a short sub.

Your wide image will be a good guide to view to be expected.

Thanks Ray, I did take 10min Lum subs and at f 3.8 it did bring out more detail



It was your shot that made me realise there’s so much dust. A surpring amount of Ha is also in the field but I haven’t included it ..yet :rolleyes: Like you I’ve put off doing mosaics but I couldn’t fit both in one frame. After a bit of fiddling, it turned out to be easier than I thought
Thanks

The dust detail is superb. When Tom Davis was posting here I always admired his images which were full of the faint dust. Nice to see you gathering images with faint dust.

Thanks Paul, I find that these dark and dusty areas are just as interesting as the “shiny” things. The complexity of what can be visible just astounds me



Thanks again Greg, I used both colour calibration and photmetric colour calibration in Pixinsight for the same result, not sure of the accuracy but, yes, interesting

A great field that captures a lot of interest George. Very intriguing and worth exploring and pulling out all the detail.

Thanks Rodney, agreed that it’s worth further exploration, next year I might add to this with some more panels to see what else there is to find, :)
