M81/M82 with SN2014J

[Avdhoeven]

Recently there was a supernova in M82, the Cigar galaxy. Last 2 nights I could image this supernova together with the ‘sister’ galaxy of M82, which is M81, aka Bode’s galaxy.

In total I got 17.3 hours of imagery for this one. I even detect some IFN (Integrated Flux Nebula) in the image from my very light polluted (Bortle scale 7-8) location.

lum: 77×10 min
B,G: 6×10 min
R: 15×10 min
Ha: 3×10 min

Filters: Astrodon LRGB (no LP filters used)

Scope: TEC140
Camera: QSI-583ws

absolutely stunning shot! congratulations in order!

Very nice indeed, yes I can see the IFN clearly....a great picture

Recently I made imagery of the supernova in M82 together with M81 in the field of view. Michael van Doorn also made images of the same area with his Hyperstar including a lot of H-alpha data. Michael shared his data and I combined this with my own imagery. The colors are much more pronounced now. I used Michael's data for the color because the luminance contained quite some gradients we couldn't remove enough to get the IFN (integrated flux nebula) out.

The limiting magnitude is about 21,0 and that's quite deep for luminance data from a 14 cm refractor. In the inverted image galaxies with magnitudes ranging from 20.5-21.0 are shown.

In total about 20h of data was used.

TEC-140 / QSI583ws: Luminance 13h (77x10 min) / RGB 3,5 h
Hyperstar C11 / SXVR-H18: RGB 1,5h (45x2 min) / Ha 1,75 h (21x5 min)

That is one beautiful image!
