IC405 & IC410 Mosaic

Had a couple of clear nights in the last few days, well one was only part of a night.

I started this two pane Mosaic (the first I have done), and hopped from one target to the other on both nights, and again just to do the Blue subs which focussed differently.

Unfortunately I didn't get as much data on the Tadpoles as the Flaming star as it clouded over prematurely (although Sat24 still showed it should be clear. Would have liked to have got some more on this, but looks like wall to wall clouds for the foreseeable. I stitched this together manually in Photoshop, but have since been told about ICE so will use that next time I try anything like this.

Flaming star:
12 x Ha (2 hours)
RGB 15 x 150secs binned
Total 2hours 37.5mins

Tadpoles:
9 x 600secs Ha (1.5 hours)
RGB 14 x 150secs binned
Total 2hours 5mins

Grand total for the Mosaic = 4 hours 43.5 mins

Atik460EX Baader 3nm Ha filter Baader RGB filters
WOZS71 and HEQ5
Mapped HaRHaRGB

Revised image which I stitched together with ICE (thanks to a tip off).

So well done, so much detail for 4.5 hours.
Awaiting the arrival of my first cooled camera (ZWO 1600mm), really hoping that it shall improve the detail of images as my most images are captured at +25 Dec celsius CMOS temperature.

Thanks Andre, yes a cooled camera will make a lot of difference, is it a mono or OSC?

It is the mono version, I went for the special that included the filter wheel and 31mm NB and LRGB filter set, CCD is not yet on the cards with my current budget and the current exchange rate to the dollar.
Cheers Andre

Mono and cooling will be a big step up from non cooled and a colour camera. Narrowband will also open up options.

Very nice, Carole. I'm trying the flaming star myself.

Thanks Jason. Good luck with your image.
I always felt the Flaming star was a bit boring on it's own, until I saw a mono image combined with the Tadpoles.
Then I had to find a way, since that FOV was too big for my set up.

That's a great image Carole and has others have commented, so much detail. I have imaged both but didn't need to use a mosaic. I am in the process of combining my Ha & RGB. I tend to use the Ha/Red combination as a HaR,G,B. Looking at your combination it looks like you've added the Ha as a Lum as well as combining the Ha with the red. Is that correct?

That's correct Steve, Combine Red and ha and use Ha for a 2nd time to highlight the detail, but does require a bit of fiddling with the colour as using Ha as a luminance layer tends to wash out the colour.
