Simeis 147 (Sh2-240), a large supernova remnant in visual colors
Simeis 147 is a difficult target due to a low surface brightness and a very large angular diameter.
Yesterday I published a mapped color version of this supernova remnant. This time I have composed the narrowband channels to a visual palette. Ionized hydrogen, H-alpha emits deep red light. Since the hydrogen is the most common element in our universum, red is dominating the view. There are some very dim bluish hues from a light of an ionized oxygen, O-III.
I collected the data for this image between 27.12.2019 and 19.02.2020.

INFO
Simeis 147 (sharpless 240), is a very faint and large supernova remnant in constellation Taurus at distance of ~3000 light years. It's constantly expanding at speed of 1000 km/second but due the size of it, we can't see any movement in it. This SN spans over 160 light years and the apparent scale in the sky is about three degrees (Moon has an apparent size of 30" = 0,5 degrees). Explosion took place approximately 30.000 years ago and left behind a pulsar (Neutron star). The pulsar has recently identified.
How long it'll takes to this supernova remnant to expand 1% large when the diameter is 160 light years and it expands at speed of 1000km/second.
How long it'll takes to this supernova remnant to expand 1% large when the diameter is 160 light years and it expands at speed of 1000km/second.
Answer is ~480 years.
(1% of diameter 160/100= 16, as kilometers ~151.372.800.000.00, = Y, km,
1000km/second is ~315.360.000.00, = Z, kilometers/year.
So, X x Z = Y and X=Z/Y, X = 480 with given values)

Panorama mosaic, Cederblad 214, Sharpless 170 and supernova remnant CTB1
his morning I published the photo of supernova remnant CTB1 (Abell 85). Photos are overlapping, so I was able to build a mosaic image out of them. image spans about ten degrees of sky vertically, that's as large as twenty full Moons side by side.! (The CTB1 at lower center has a same angular diameter as our Moon.) Photo is taken with the Tokina AT-x 300mm f2.8 camera lens, Apogee Alta U16 astro camera and Astrodon narrowband filters. Info about my current setup here, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html

INFO
Abell 85 is a very faint supernova remnant in constellation Cassiopeia. It's difficult to image with any details due to extremely low surface brightness. Abell 85 has a largish diameter, about half a degree, it has a same apparent diameter as a full Moon. The physical diameter is about 98 light years across. This SNR locates about 9800 light years from the Earth. CTB1 was originally thought to be a planetary nebula and it was included the Abell catalog of planetary nebulae under a name Abell 85. It was confirmed to be a supernova remnant by Willis & Dickel at 1971.
