Thanks guys..👍.....this is now my desktop background on my own new 4K monitor.

Great image. More data will indeed improve the end result - but great image as is!

With Covid-19 lockdown and lots of rain - it was a good day to re-work some data from Sept. 2018. This is NGC 281.....Pacman Nebula. Total exposure time here is 24 hours (Narrow Band and RGB data). Quite pleased with the improvement I made on this since last I processed it. The full image covers a wider area, but the crop here allows greater detail on your screen.

......I was just wondering........like I said, I don't do much "RGB" images because of the general light pollution. .......so thanks for the reply. (.......but I will still just use the RGB filters I think......I can be a bit lazy at times and in the end I don'tthink the L filter data would do much for my broadband images 🤣)

I am guessing that you are shooting at x1 (not binned) on the RGB filters. Don't really understand then why you bother with the L filter. I don't do much RGB (as you know) - when when I do, I never now use the L filter.......that's my focus filter for the NB stuff 🙂.

Yes - looks like your spacing is correct. The only thing I can think of is perhaps pinched optics; i.e. things just screwed together too tightly. A bit of a long shot.....but I do believe that it happened me once. Unfortunately I cannot confirm that I had the exact same problem show in the subs......but I do know I had problems of some sort in the corners.

In truth Rodd....the 1st was fine - though I can see what you achieved with revisiting it. Had it been mine....I doubt that I would have touched it. Either one gets my vote.

......and don't forget all the new satellites that are up there 😟

That's the key point Rodd. Yes it is quite faint but when you look at the one referenced above with 40 hours of data it really is a beauty.....so I know where I have to try go with this.....I will aim for up to 30 hours. Unfortunately that looks more and more like later in the year....cloud not too bad tonight BUT is is blowing hard 🙄. All part of the fun......😏

I think it was here that I saw this object first - Jedi2014 posted a beautiful image of it in the past.

Thanks for the comments guys - yes it definitely needs more time. Just, as I said, it is the wrong time of year......but still open to a little every night that is clear. I will have to wait & see ......I just don't have the patience that Tom has ....🤣

Not too sure if it is really worth posting this. It is really the wrong time of year to try capture data for it but I wanted to keep working with NB filters for as long as possible (before turning to galaxies). I was trying a few different targets during the night (when I had the chance) - this one was 1st on the list each night. So far there is 5 hours each Ha & OIII with 1 hour each RGB just to help. I hope (but am not at all confident) to get more for this ..... but it may end up being put aside until September before finishing. There is not much structure to this old planetary nebula....but I am confident, that with more data, it could be well improved on.

Check out "CTB 1"

Spectacular - I just loved roaming around on that 'Zoomify' image and I know I will go back to it again & again....... Congratulations AGAIN.......I just don't know how you can be so patient and persevering.....but I do know that it pays dividends for you Big Time!

Thanks Steve. 👍

Thanks Mark. I now have a higher res image available on the web site.....http://www.kinchastro.com/ngc-2259.html (Click on the image on that page to get to higher resolution).

I think so.....as it is, this area is not available for very long past midnight.......but the nights have beeen so humid here where I am (Murcia by the coast), that sometimes I am just happy to pack up a bit earlier.

NGC 2259 is actually the small open star cluster at the top margin of the image - just right of center. I have no info/names for other parts of the image. Just found the area when looking around near the cone/fox fur regions......thought it would make an interesting area for an image. This is a total of about 13 hours Ha, OIII & SII. I have some RGB so maymake a different final image when I have the time.

Wow! Love it Tom. Another huge piece of work that one could just get lost in......looking forward to being able to browse around this in high resolution 🤩

Thanks Mark. I have just now put this up on my web site and it is possible to have a closer look at the cropped images of the Horsehead and the Flame areas. http://www.kinchastro.com/horsehead--flame.html Though maybe I shouldn't have 🤣🤣

This is not - by a long shot - the best Horsehead & Flame that you have ever seen. But from my point of view, I am happy to have managed it in very "wet" conditions. (Relative humidity averaging about 90% when shooting this). At first I was concerned about Alnitak and its overall effect - taking over the image. But when I put the subs together, I realised....hey, it is a very bright star and as long as there are no very wierd artifacts I might as well just leave it. It was never meant to be a major project to produce a fantastic image and in that, like I said, I am happy enough with the result. (I will put it on my web site later today and those interested can get capture details there).

Thanks for the comments Olly. I have been spoilt in not having to deal with Alnitak for some years - it now stands out like a sore thumb to me. It looks much worse (to me anyway) at the higher resolution on my screen.....and not something I am used to dealing with. With that in mind, your pointers & link are very welcome....I don't think more data will be an option anytime soon. Thanks again 👍

I'd be interested to know too, if anyone has ANY solution. The different brand filters leave one with different effects and the last time I shot this area I had a hard job calming down what my Astronomik filters left me with. Last night I was imaging with an Astrodon Ha filter but with very humid conditions - so more problems to be sorted....part screen shot to show what I mean. Tonight I am imaging with RGB filters (still humid conditions) and it is no better 🙄.....worse even! So - I must prepare for lots of time processing.....what fun 😏

Thanks - that's nice of you to say so. 👍
