A new version of the M1 nebula with addition of SII data.

My latest rendition of the M1 with the data acquired from the CDK24. 

Just a mere 7 hours of intergration time (5 hours HA and 2 hours O3).

My latest Narrowband image of the Dolphin Head Nebula. Acquisition details can be found below. There are some RGB data involved (only for the star colour, not sure if it is allowed or not but I post it anyway).

Thanks, every one. The pulsar animation blows my mind too.

The passing clouds messed up the animation but I was still able to get a good look when the prom lifts away.
It's a shame I did not get better transparency.
The animation is taken at my remote observatory in suburb Ha Noi, Vietnam in 10-11 AM 23/11/2023

Just in time for a solar animation.

After a boring week, the Sun is back with a new gang of ARs and oh boy do they deliver. The animation is so action packed that I can stare at it for hours and still find new things. There's corona rain, a mini flare, some surge action and a lot more. The seeing was good and it shows on the animation, it's a long time since I've done anything. I took some time off to upgrade the mount.
Enjoy!

Another Jupiter animation. still from the C11HD with QHY5III715C

A big thanks to the Judges and every other Competitors. I am honoured.

Off topic. Sorry for not reading the instruction

Oh wow, I am honoured I got the prize, there are many superb works submitted, I really did not expect I'd win. Thank you all for the kind words! I really enjoyed the competition.

Well, I liked @Minhlead wolf rayet 134 so much I had a go myself - a bit of a different framing, and SHO(ish). This was only 5 hours however - the first clear night we've had in donkey's years.

I had taken my scopes out of the observatory for the summer, and somehow managed to screw up the back focus on my Stelamira 90ED with FF - but it wasn't too bad in the end. Certainly one where more integration would help a lot - but with the summer this year I'm trying to shoot new targets each night, since those nights are so few. I think this is my first new image in over 2 months!

Shot with asi2600, L-ultimate and processed in affinity photo and Sirl.

You did great, Stu. Well done!

This is another entry of mine. A rendition of the magnificent Wolf Rayet 134 . Acquisition data can be found below the image

(Animation) Multi-legged prominence 22 Jul 2023

If the "Ring nebula" is discovered by a modern astrophotographer, I believe it should be named "The blooming flower nebula" instead of merely "The Ring" nebula which sounds mediocre.
Easily reached even in heavily light polluted sites even without any filter, M57/core is quite bright. But with the right equipment, sufficient exposure time, and an adequate dark site, the outer shell now shows with lots and lots of unseen details.

Another entry of mine. There is nothing in the solar system that comes even close to the sight of a post-flare corona rain. 

Taken 12 Jul from my 150mm solar scope with Quark Chromosphere double stacked with PST etalon. 

Cannot wait to share this with you guys.

Everything in this animation of flare is mesmerizing to me. From the seemingly serial explosion, the elastic movement of the proms to the small flare on the AR. The seeing was not that good. But I still managed to get this 1.3 hours timelapse. Hope you enjoy it as much as I did.

Phewwww. It's here at last, just on time! This one is specifically taken for the competition when I got the chance to have a few personal hours with the big gun.

Below is the M63 Sunflower Galaxy taken in 2 nights 18-19/June 2023. The data set is a mere 66x120s with only the UV IR cut filter.

The scope is CDK600 with QHY168C camera.

That's a cracking good image, but I'm slightly puzzled by the date mentioned.  19th May was the date the supernova was discovered by Koichi Itagaki.  And it certainly hadn't faded after a few days - I imaged it (in Astronomical twilight) on 24th May and it had brightened considerably as seen below.  QSI683 on RC10. Luminance 11 x 5 minutes, RGB each 5 x 5 minutes, all binned 2x2.

Date correction needed  perhaps?

Cheers, Peter

Thanks, Peter. I stand corrected. The data was accquired on May 20. I saw my image on astrobin was posted on May 20 and thought the data probably acquired the night before. But yeah, it seems I was so eager and process the image just a few hours after the data taken. Thanks for weeding out the error.

About the fade out of the supernova, I did not participate in the follow up observations (just look at the spectral of the supernova the following nights so I do not have a clear perspective of time. But yeah, after this image was taken, the supernova goes up considerably in magnitude and then faded away red shifted (probably in the span of a week or so).

Another entry is an experiment that I do on my smaller Sharpstar 107PH.

The image was captured from my remote observatory in the skirt of Ha Noi, Vietnam. Although I used a relatively small fracs (107mm) the result was pleasantly detailed, in part due to the processing technique that involves BXT.

I hope this is not too late.

The image of the M101 on the night 20 of May.

Since there is a supernova going on, I got the chance to play with Vietnamese's largest scope. The CDK600 hosted at Explora Science Quy Nhon - Binh Dinh - Vietnam (I acquire the data myself remotely)

The supernova shows with a striking blue color (it even shows some blueness to the naked eye via the big scope, I've been told by someone had the chance to look at it visually.). A few days later the supernova shifted red and slowly faded away. 

Image taken via CDK600 and a QHY168C.

Oh this is wonderful. This time I have 2 pictures to show for it. (Warning: Large file)

First is a Full disk mosaic with 41 tiles (I am using a Quark Chromosphere double stacked with PST etalon on a 6 inches fracs so the FOV is very small, getting fulldisk on this was a real challenge. In return the details is incredibly nice. Please open the image in new tab to see the disk in full detail. ) Taken 1st June. There was a big storm out in the ocean so I have excellent transparency and seeing for a few days in the beginning of June.  the good seeing shows with the timelapse and the fulldisk mosaic.

2. Secondly, a timelapse of the small proms with a small flare on the NW Limb.  Taken 1 day later. The good seeing manifestes as a extremely detailed, tack sharp animation. 

An inverted fulldisk that I took yesterday (09 April).

Cam: Playerone Apollo M-Max

Scope: Askar FRA400

With the greatest respect to SGL members: The questions you ask are for the solar specialists of the Solar Chat forum.
Many members there have decades of experience at solar imaging, processing and observing.
Few questions go unanswered, over there, simply because so many different things have been tried.
The depth of knowledge is astonishing and the friendly tone is supportive of all levels of solar work. Even mine.
 

I already registered an account there. Stephen Ramsden there is a friend of mine, he has been extremely supportive and helpful. Will head over there now. Thanks
