K3's Astronomy - Supernovae
"When I consider your heavens, the work of your fingers, the moon and the stars which You have set in place, what is Man that You are mindful of him?" -- Psalm 8:3,4

Camera: Vesta 675SC + 0.6FR
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F3.6
Exposure: 37x32s (gain 100%), 25xDF
Seeing: lim.magnitude for naked eye 4.5, temperature 1C

Finally I succeeded to capture spiral arms in M74.

SN2002ap - Hypernova in M74. 5.2.2002, 20:39 (19:39 UT)
Resolution: 3.14 arcsec/pixel
Camera: Vesta 675SC + 0.6 Focal reducer
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F3.6
Exposure: 31x20s (gain 90%), 25xDF
Seeing: foggy, lim.magnitude for naked eye 4.0, temperature ~5C

Foggy weather and 31 altitude of M74 didn't allow me to take better photo. Red foggy background didn't allow me to take longer exposure.
Negative of above picture.
M74 region in grayscale.
The same AVI source as above, but 59 frames were summed instead of 31.
Hard processing was used - I tried to reveal some spiral structure of M74 in the photo.
Two arms are slightly visible.
