The sexy bit of the American Nebula

Horsehead IC434

Rosette Nebula

Under quite windy and not great seeing conditions I managed to get something of the biggest planet. Two of Jupiter’s moons can also be seen to the right.

Decided to revisit this data to see what could be pulled from it. This is only 30 mins of subs so just playing around. Amazing what detail you can get with only a few minutes and a relatively small CCD camera, just imagine what a few hours of data could do! The Horse-head Nebula (also known as Barnard 33) is a small dark nebula in the shape of a horses head, found in the constellation Orion. Located just to the south of Alnitak (the bright star visible in the picture), which is the easternmost star of Orion’s Belt. It is part of the much larger Orion molecular cloud complex, and can be seen here with the Flame Nebula (NGC 2024) also part of the same molecular cloud. The Horse-head Nebula is approximately 1,375 light-years from Earth.

Here is a close up view of sunspot AR3315, with a rough scaled image of the Earth to show the shear size of this grouping. Sunspots are cooler areas on the surface of the sun with the dark central dark umbra reaching approx. 4500 Celsius compared to the rest of the surface, which is approx. 6000 Celsius. It only appears darker as it is so much cooler. If it was on its own it would shine incredibly bright.

NGC1893, a 4 million year old open cluster situated in the constellation of Auriga, which contains the H-alpha region IC410, more commonly known as the Tadpole Nebula (so called because of the two tadpole like structures “swimming” towards the centre of the nebula. It is located 12,000 light-years from Earth, and is a region of ionised hydrogen gas spanning over 100 light-years across that’s carved and sculpted by streams of charged particles called stellar winds emanating from open star cluster NGC 1893.

Taken 28/10/22. Celestron C9.25 with ASI120MM, on HEQ5Pro guided using QHY5 on a 9×50 scope. 60 sec exposure, processed using Autostakkert, with wavelets done in Registax.
