M81/82 Deep, deep field...

Recommended Posts

Recently I made imagery of the supernova in M82 together with M81 in the field of view, which I published here.

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.

The limiting magnitude is about 21,0 and that's quite deep for luminance data from a 14 cm refractor.

After that I also caught some extra H-alpha data to get out even more details in the galaxies and combined old data from 2 years ago taken with my C11 of M82...

In total about 23h of data was used.

TEC-140 / QSI583ws: Luminance 13h (77x10 min) / RGB 3,5h (21x10 min)/H-alpha 2h (5x20 min)
Hyperstar C11 / SXVR-H18: RGB 1,5h (45x2 min) / Ha 1,75 h (21x5 min)
C11 @ f6.3: Luminance 1.3h (8x10 min)

Is that shot from Holland? Very, very impressive.

Yes it is, just 15 km below Rotterdam...

I just get orange skies, but then I am walking distance to Schiphol. :-(
