This is a LRGB image of NGC 4725 Galaxy.
I Originally image this back in 2018 but due to the poor conditions I could only get 2 min RGB subs and 1 min luminance subs (3h total imaging time) and at the time promised myself I would return to this object. I originally started working on this back in March but got frustrated with it and moved on. I had forgotten I had the data until now and decided to give it another go, well this is it with longer RGB & Luminance subs with a combined total of 6h. I still had to discard some RGB subs and quite a few luminance due to the transparency of the sky or lack of it☹️. I discarded 30% my 2min luminance so I combined them with 43 of my best 1min Luminance subs from 2018.
I tell you one thing galaxies (well most of them) are fiddly little buggers to work on and I find they take a lot longer to process than nebulous so please 🙏 role on summer Nebulas.

The Oslo Opera House is the home of The Norwegian National Opera and Ballet, and the national opera theatre in Norway. The building is situated in the Bjørvika neighborhood of central Oslo, at the head of the Oslofjord. It is operated by Statsbygg, the government agency which manages property for the Norwegian governmen
The lobby is surrounded by 15 m (49 ft) tall windows with minimal framing and special glass that allows maximum views of the water. The roof is supported by thin angled columns also designed not to interfere with views.
Interior surfaces are covered in oak to bring warmth to spaces in contrast to the coolness of the white exterior
This is kind of an of things to come photo. I'm wanting to start a series similar to this so, uh... yeah.

Jupiter on September 11th. Transparency was above average with little to no wildfire smoke in the sky. Seeing started out around average, but got a but better as the night went on. For Jupiter you can see Oval BA with it's slightly yellow/orange tinge to the lower left and several white ovals lining up to the right of it.
The roof is broken, the halls are empty - remains of one of the largest mechanical engineering factories in the former GDR
A morning in a glacial lake in Western Norway. As the sun rise above the mountains the lake gets transparent.

Very similar to a post awhile ago just a slightly different composition and reprocessed.
Sadly I wont be doing much photography in February as I am away 5 days a week on Tour. I will be taking the camera but if I do get chance to take any photos they probably wont be of the sea and I probably wont have time to plan my shots like I normally do :-(
