Bode's Galaxy

Postby Aratus » Wed Nov 21, 2018 1:46 pm

Messier 81 or Bode's Galaxy is located in Ursa Major. It is easily found through binoculars or a small telescope. If you imagine the 'bowl' of the Dipper to be a bad square, then draw an imaginary line from the bottom left star to the top right. Extend that line by the same amount and that is the location of M81. (M82 - another galaxy is nearby) The bright oval core is normally all that is seen, but there are a nice set of faint spiral arms. I've never caught any stucture before, but on this image taken recently, I just about managed to capture the spiral arms.

This is taken using the Canon, and a single 45sec image.
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.

Some very nice spiral arm structure there.

Did you get any more images to stack with it?

Yes, but they were deleted after I throught they had been copied. :? However, the originals should still be on the computer in the observatory. When I get time I'll copy them over and see if I can get a better result. In any case I can take some more on another occasion . I'm hoping to set up some manual guiding, and with a light polution filter, I'm hoping for some longer exposures with better contrast.

If we had a LIKE button on this forum you'd get one from me!

I've heard claims from a reliable source of it being seen with unaided eyes.
How can I be one with the universe when we don't know what 96% of it is.

I wouldn't be surprised - in a dark site. The core is relatively bright.
