Astrophotography / The Bubble Nebula and its many...

Last post by JohnH - Oct 30, 2024, 18:34:45

I cannot get the image to show! so here is a link.

https://www.astrobin.com/qtg1rl/

This LHaRGB is a total of 4hrs 47mins imaging over two nights and I really felt the benefit of my observatory - no need to set up, take down etc.

Sharpstar 15028 HNT telescope on iOptron CEM25P
Camera ZWO ASI1600MM Pro at -10C
Control ZWO ASIAir Mini.

The area around the Bubble Nebula (C 11) is full of objects:
To the right is M 52 (open cluster)
To the left SH2-157
Just below C11 and SH2_157 is SH2-159
Below SH2-159 is NGC 7538

The "Bubble" is dead centre of the image and is visible if you zoom in (couldn't get it quite as contrasty as I would have liked!).

I still think that the Bubble, together with its neighbours, is the most beautiful DSO.

Possibly the longest imaging time I have managed.

Astrophotography / Solar WL and A3 from Petts Woo...

Last post by Roberto - Oct 23, 2024, 11:54:33

Hello

First some solar in the afternoon:

Sun WL - 19 October 2024 - AR13856, 3858, 3859 and 3860 - 14:38 UT

Details here: https://www.astrobin.com/bplv9l/C/

Seeing wasn't great but here are some close-ups of nice active regions using the 10" f/20 Mak:

AR13859

AR13858, 3860

And then imaged the comet between 18:50 and 19:40PM or so:

C/2023 A3 (Tsuchinshan–ATLAS) - 19 October 2024 - 18:15UT - RGB

50x45 second OSC images using a 92mm refractor at 491mm EFL and ASI2600MC.

Details here: https://www.astrobin.com/a2df8n/B/

Some colour around the trailing nucleus and a bit of detail in the tail. FoV doesn't really do justice to the tail or the anti-tail which is barely showing in this shot because of my focal length.
