    Here's "The Whirlpool Galaxy" M51. Its something I don't get a lot of time for shooting due to it being in the optimal shooting position this time of year (which happens to be the cloudiest most years.)

    I shot it at 1300mm and applied a 2x drizzle algorithm to enlarge it. 36 minute total exposure time.

    Cool, that is crazy how long of exposure that is. What type of apature do you shoot with?

    that's a pretty incredible picture. i can't believe how good the detail is. It almost looks like at the end of one of the arms is another galaxy thats about to get pulled in...

    The aperture is F/6.3

    I think that particular galaxy is actually a galaxy and its companion galaxy which the larger is pulling stars from.

    how do you compensate for the rotation of the earth if the exposure is 36 minutes?

    The scope mount is aligned with true north and a drive motor keeps one axis moving to stay fixed on the object.

    A scope and mount like mine can be had for about $1200. The mount is pretty minimal to do the job. Mines bolted to a 2500lb concrete pier thats buried 4ft into the ground in the middle of my observatory so it helps make it much more accurate.

    I'm just glad I no longer have to spend an hour setting up the scope everytime I want to use it. Risking tripping in the dark with all that gear is getting harder as I get older.
