About this object
Sh2-36 is listed as a HII region in the sharpness catalog in the constellation Serpens. It measures near 50 arc minutes in size. However, the emission signal is super weak and the majority of the nebula seems to be more of a molecular cloud and dust. The is a very weak signal in hydrogen as can be seen in the above 10 hr continuum subtracted H𝛼 image. There is also some very weak emission nebula in the background. However, this nebula was probably mis identified on red sensitive plates by Stewart Sharpless. The full resolution image is available by clicking on the main image. If you scan the full resolution image, there are many small and faint galaxies in background. Some have interesting shapes. The brightest is NGC 6070 at magnitude 11.78. NGC 6070 is 3.8 x 1.8 arc minutes in size and is near 100 million light years distant. At that distance the real diameter of the galaxy is close to 104 thousand light years. NGC 6070 is moving away from us at 1997 km/sec.
The bright star above NGC 6070 is HD 145204 at mag 6.68. It's a variable KIII orange/red star 43 times the suns diameter. The other bright star on the upper right side of the image is HD14472 at mag 6.8 and 162 light years distant
The image was acquired by Jon Talbot and Calvin Carter using a Planewave Delta Rho 350 and ZWO ASI 461 camera from Deep Sky Observatories Collective in Ft Davis Texas.
