Cederblad 214, the Cosmic Question mark in visual colors

I have published this target in mapped colors at 9.2. 2020, it can be seen here, https://astroanarchy.blogspot.com/2020/02/new-photo-of-cederblad-214-cosmic.html

This photo was taken with my "new" imaging system. I managed to mate an old Tokina AT-x 300mm f2.8 camera optics with the Apogee Alta U16 astro camera and filter wheel. Some angle grinder was needed to have enough back focus... More info here, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html

This photo of Cosmic Question Mark has a great symbolic value for me. The cosmic curiosity is the very reason I'm doing this difficult, and sometimes frustrating, form of nature photographing.

Photo is in natural colors combined from narrowband channels. An ionized hydrogen, H-alpha, is emitting deep red light and it's dominating the color scheme. Bluish hues are from an ionized oxygen, O-III.

 INFO
This cosmic question mark, in constellation Cepheus, contains following objects; At top, Cederblad 214(Ced 214) surrounded by NGC 7822, a dot like nebula at the bottom is known as Sharpless 170,(Sh2-170). Image spans over Five degrees vertically. Distance from my observatory, is ~2750 light years and it spans about 40 light years.

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.

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

I published the Cosmic Question Mark, Cederblad 214 and Sharpless 170 at February 9,
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
