Description

Herbig-Haro 24 is probably the most fascinating object in the sky. The image above features very detailed view of it, imaged remotely using 1m telescope in Chile.

I find it interesting that at this level of detail the whole nebula in the image does not look like a solid object anymore. You can distinguish lots of details, lots of light sources of different colors inside the dust. In some places you can also get some idea about 3D structure of the whole thing. I think I spent hours looking at it already.

There are lots of details in the image which I think deserve attention.

Rev. B shows a crop of the original image with many red hydrogen clouds which I am sure associated with HH 24. You can kinda see a very dim reddish "bridge" connecting HH 24 with some of the HH objects on the right. There are lots of them, many more than you would note at first.

Rev. C shows recently discovered McNeil's nebula, discovered only in 2004. It is known to change its luminosity over time. Also note a line of dust on the very bottom of Rev. C that was also illuminated, but disappeared. Definitely one of the most intriguing objects in the sky.

Rev. D shows a comparison of positions of HH objects in 2008 and 2018. They definitely moved a little bit to the right, away from HH 24 over the course of 10 years. Images from second POSS survey also show some movement, but I didn't include them because of their poor quality.

Rev. E is a zoom in on the most interesting object in the image - HH 24 itself. You can note quite a few differences, but primarily - movement in a jet to the right! Quite fascinating to be able to image that. Just imaging that. Also take a look at this APOD with an image of HH24 taken by HST.

Rev. F shows a BW crop of the image with all the HH objects. BW used to get rid of all color differences due to processing and it allows to better appreciate on all the changes in the area in 10 years.

-------------------------------------------

2008 image is taken using MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile and processed by Igor Chekalin (released here).

2018 is taken by me remotely using 1m scope in Chile. LRGB 14:10:10:12 x 600s
