That is a wonderful image. Something i've not seen before. And as a Scotsman I just have to love it!!!

This is a 3 panel Mosaic within Cygnus. It is around 2 hours per channel/panel and is processed in a dynamic HOO palette. Sharpstar 61EDPHII, QHY163M, ZWO 7nm Ha and Oiii DHoo_L_reducedIC.tif

that is a lovely image with super detail.

Super view. Well done.

I really like that. Well done.

Thats really nice. great structure in the main nebulae.

Thanks Robin. So it was really all about careful masking. I used PI's game script to produce the initial Gradient edge mask then trial and error with HT and convolution on the mask to get something that preserved the galaxies without producing artifacts at their edges. I also made the mistake of not including the two smaller galaxies NGC2976 and NGC3077 in my initial masks. And i did not keep an eye on them as the processing continued until, at the end, they were totally blown out and stood out like sore thumbs 😂. So I had to basically go back and start again! Good luck, I look forward to seeing your mosaic - are you doing it with the RASA? That will be brilliant.

Thanks for that. No, not imaged separately, just one set of subs and very careful masking. I have a set of subs taken at a higher FL with better detail in the galaxies and I'm thinking i may try to graft them into this.

I imaged this area about a year ago with my 80ED but was never that happy with the result. So I gave it a go this year with my 61 EDPHii. This is 6 hours of 180s subs with the ASI2600mc and the L-pro filter

After almost exactly two months since my last clear sky I got my first image of 2023 on 13 February! This is a target I've wanted to do for a long time but its very low for me and by now its getting late in the season. And then the clear nights were not clear as long as forecast. So this is only 3.5 hours of integration and it needs much more. But that will not happen this season! ASI2600mc, Sharpstar 61 EDPHII Altair L-pro. Thanks for looking.

Fantastic image, Such depth and detail.

Both are super images but i do prefer the second, the blue grey shading to the browns gives more sense of depth.

Lovely image, great colours and detail.

thats an excellent image. ncely done.

I really like that. the colours and definition in the cores are excellent

I came accross this data while filing everything from my pre-christmas spree of several nights imaging. I had forgot all about it. Its only 4 hours, captured in less than ideal conditions (99% moon) with only an L-enhance. I think its come out ok considering. The Rosette Nebula sits above the RHS of this and I plan to do a 2 panel of it. 80 x 180s, Sharpstar 61 EDPHii ASI 2600mc and Optolong l-enhance. processed in Pixinsight using Blanshans HOO normalisation method.

thats lovely. The tadpoles show very well swimming in their "Blue lagoon"

Thats superb, never seen the two in one FOV before. Excellent

thanks @Vlaiv, I've just posted it up so you can take a look if you are interested. The overlap does cover the pillars area in NGC7822 and i dont think they hare significantly degarded - as you have explained/

This combines a panel taken with my 61EDPHII (275mm FL) with and my earlier 2 panels made with my SW 80ED (510mm). It was intended to show the cosmic question mark but unfortunately the 80ED panels cut off too much for it to show well. I started a thread on Processing Tips asking about which would bethe best panel to register against (thanks @vlaiv) This one was done with register against the middle 510mm panel so, as Vlaiv explained, the lower panel may look a little more blurred. i'll probably go back and do it again registering the other way. Its Around 3.5-4 hours per panel all done with the 2600MC, L-enhance and processed using Pixinsight and Bill Blanshans HOO normalisation method.

thats asuper image - nicely done.

Thanks Vlaiv - thats exactly what I needed! As a follow up question, what happens the second case (registering to the 510 panel) in the overlap area. I the image I am working on there is an overlap area which holds some quite small detail. Will the 275mm panel significantly degrade this area of detail? I have already processed the image this way (registered to the middle 510mm panel) and i am relatively happy with it. I think the lower panel (as you indicated) does look more blurred but as there as not much in that panel I was willing to live with, I'll post that image up in the DSO page. Thanks again

I have 3 panels for a mosaic. All taken with the same camera but 2 panels (top and middle) at 510mm FL and 1 panel (bottom) at 275mm FL. I will build the mosaic in Pixinsight using Photometric Mosaic Script and can do that without problem. Unfortunately I dont really understand the whole resolution/upsampling/downsampling business well enough so am struggling to decide which panel to use as the reference image such that I dont lose any detail or resolution in the process. Any help would be appreciated

This is the next image from my haul of last week. It is 4 hours of 180s subs with the sharpstar 61EDPHii, ASI2600mc, L-enhance filter Processed in PI using Blanshans HOO normalisation method.

So, after a run of clear nights, most of which were forecast as total cloud cover, I have a few images to process. This is one I've wanted to do for a long time but never has the conditions. This was the last target I captured but the first to process as I was interested/excited to see how it came out. At a total of 10 hours integration its the longest one I've done to date. Its 200 X 180s, Sharpstar 61EDPHII, ASI2600mc, L-enhance. C7C welcome and thanks for looking.
