Also known as h and χ Persei, the Double Cluster (comprising NGC 869 and NGC 884) is a "line of sight" pairing in the constellation in Perseus, though actually they are only a few hundred light years apart. The clusters have a combined visual magnitude of 3.7 and 3.8 and are visible to the naked eye as a fuzzy patch between Perseus and Cassiopeia.
NGC 869 (top) has a mass of 3700 solar masses and NGC 884 weighs in at 2800 solar masses; the total mass for the complex is estimated in excess of 20,000 solar masses when including an extensive halo of stars. Based on their individual stars, the clusters are relatively young, both 12.8 million years old, with the hottest stars having spectral class B0; NGC884 also has 5 prominent red supergiants including variable RS Per (closest to the centre of the lower cluster). North is to the left in this view.

I'm from Hungary. This is my first post. I am glad to be here.
Recently I'm trying to sketch some deep-sky objects. I've made this observation yesterday. Cygnus was near to the zenith and the sky was pretty dark.
NGC 7000 is one of my favourite target. I like to observe it with any telescopes, especially with RFTs and with UHC filter.
Please excuse my language errors.
Last week on august 5th we were treated to a coronal hole followed by some G1 auroral activity here in New Zealand.
Unfortunately I live a bit too far north to capture the spectacular Auroral images.
However, ever the optimist, I set my canon 6d with a Samyang 14mm lens up in my backyard and captured 300 or so shots (20 seconds at iso 3000) which I then sent through to lightroon timelapse.
I'm quite pleased with the result. Definitely some colour there.

A series of time-lapse short videos set in different locations within South Hampshre at night. All scenes were taken between a Bortle 4-5 area, and each clip equates to 5-6 hours in real time. Please check your volume as this video contains music.
Equipment / Software:
Tokina AT-X 11mm - 20mm
Adobe Premier Pro
Alexander Blu - Background Music
Note: My first time producing a proper time-lapse video. Unfortunately the amount of noise and hot pixels were much worser than expected when I reached the video editing stage, and I need to learn how to apply darks against individual frames en masse. I am not personally satisfied with the final quality, but still thought I should share with what I have on here.
Please feel free to leave a comment, critique, suggestions and guidance on here, thanks!
I was lucky enough to spend Easter in Mauritius and managed to get a night of imaging in despite the tropical night time clouds! As someone who lives in the Northern hemisphere, the Carina nebula has always been a target I've coveted, but during my holiday, I also loved Crux as prominent constellation in the Southern sky. So when I ran into polar alignment issues with my Skyguider Pro, I decided to play it safe and go for a wider field, capturing both those targets rather than focusing purely on Carina as was my original goal.
This was shot from my father in law's rooftop in Bonne Terre, Vacoas, Mauritius and my basic polar alignment meant significant field rotation, but I still got some usable data. Cropped, processed and finally upsampled.
Data was shot at f/2.8 with a 50mm lens, unguided on an unmodified Sony a6500. 174 lights at 30 secs each = 1.4 hours of integration. Bortle 5.
From the colours it looks like these objects sit right on the disc of the Milky Way and I know there is more in the picture I haven't mentioned!
Thanks for looking!
