Image Description and Details : NGC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
The nebula has an overall bubble shape, but with complex filamentary structures.

Image Description and Details : After a few months off while i had planetary equipment on the mount. The RC is now back on the mount for some deep sky imaging again. Starting with the Bubble nebula or NGC 7635. 8000 light years away in the constellation Cassiopeia. Captured from my Bortle 5 backgarden in west sussex over many nights. I also added the data i captured back in 2021, as it's a target i find fascinating and keep returning to.

Image Description and Details :

Shot in true color (with Ha added) in Borrego Springs earlier this month at the Nightfall star party, this is one I have attempted several times at home and it's never really worked out. It needs a dark sky. Casper is a rather famous reflection nebula in Orion not far from the Horsehead and the Great Orion Nebula. About 1,500 light years distant, Casper is a dynamic star-forming region containing about 45 T Tauri stars (young stars that are still forming) and 17 Herbig-Haro (HH) objects (objects that are not quite stars but presumably will be soon). Several of the HH objects are visible in the image as bright red dots surrounded by cold, dark dust.Details: Celestron EdgeHD 1100 telescope with 0.7x reducer; 10Micron GM1000HPS mount; ZWO ASI6200MM camera; Chroma LRGB filters and Chroma 3nm Ha filter for the hydrogen-alpha signal); 9 hours exposure time.
