This is part of the huge Orion molecular cloud of dust and gas which acts as a stellar nursery.Theres no getting away from the fact that most of the stars in this image are brown! – due to overlying dust.
In the centre of the image, two young B-class stars (HD 38563A and HD 38563B) are reflected in the surrounding gas with an overlying dark arch.
Towards upper left is another reflection nebula, NGC 2071.
NGC 2064 and NGC 2067 are the two bright zones above the dark arch.
Towards the lower right, some early stars are just managing to penetrate the darkness as red or yellow splotches. One of these splotches (triangular – just to right of two small stars) brightened considerably in 2004 – its thought a young star ignited at that time – the region is called McNeil’s nebula after the amateur who noticed it.
Infra-red imaging shows about 45 new stars in the early phases of development in this cloud (T-tauri stars or Herbig-Haro objects which are outflow jets from young forming stars).
Image acquired remotely from the Mayhill observatory in New Mexico.

The bright Orion belt star, Alnitak (O class), lies to the left (you can just see that it has a companion – B class).
The Burning Bush or Flame nebula is just below that (NGC 2024 or Sharpless-2 227).
To the right is Barnard 33 – the Horsehead dark nebula – dense, cold dust and gas backlit by a cloud of glowing hydrogen gas (IC 434).
Go left and downwards from B33 and there are two dust/gas cloud reflection nebulae lit by bright stars. The larger one is NGC 2023.The smaller is IC 435.

I started to image M51 a little while ago but only got 4 x 5 minute subs before the clouds came in – frustrated I gave up!
Its going to be a cloudy weekend here so I tried adding those 4 subs to my images of M51 taken about a year ago.
I think it has helped but I really need to get a bigger scope if Im going to get better galaxy images.
2 small spiral galaxies to the NE (if N is at the top) are IC 4263 and NGC 5169.
Also first use of drizzling technique in PixInsight to help improve resolution.

I have waited SO long for a clear night and at last it came! Orion is now low in the sky so this was my last chance to image these targets for this year. Set up as usual and wasn’t sure if I had a great polar alignment – also, the Orion nebula is so bright that long exposures burn out easily so I chose 2 minutes as a good compromise. I was keen to use “dithering” with my auto-guider as it is said to reduce noise and bring out subtle detail – seemed to work very well. Am also now using “Neat Image” anti-noise software which has made a big difference.
Although it doesn’t look like much, I am very fond of open cluster NGC 1981 as it is the first object I looked at in a star atlas then decided to try and find with my telescope (a 8.75 inch Dobsonian). My old sky diary from 2009 is here: http://www.johnapurvis.synology.me/sky_diary.html

Cloudy, windy, rainy!
Promising this AM but just got cloudier: one run in white light with the 1000/102mm refractor: AR 2282. the upper spot shows some light bridges dividing it into segments.
Today’s Sun imaged in Calcium K. the top image shows a nice pair of loop prominences – certainly, the largest loop that I have imaged in CaK.
The middle panel is a mosaic made of 7 separate smaller panels and the bottom image is a single panel showing Active Region 2209.
A little micro-flare (or an Ellerman bomb) was visible at the edge of the penumbra of AR 2216 – red circle (click to enlarge).
