M109 and a personal distance record

[windjammer]

Here is M109.  I have been fiddling with this image ever since taking exposures throughout April and May (a wet Spring).  Still can't get the galaxy or the stars looking right.  A bit grumpy seeing the effort it took (16.7 hrs exposures), but time to let it go.

Three pics here: M109, M109 plate solved and annotated, and NED (Nasa Extragalactic Database) entry.

On the upside, a personal distance record - a billion light years, give or take

Galaxy PC37796 (the speck, lower left of the image) has a NED entry for its Hubble distance as 275.2 Mpc, or 900 Mlyrs, and recession velocity 18,600 km/s !!!

Imaging scope: SW Startravel 150mm F5 Refractor, Atik 460EX mono

Ha: 32x600s - 5.3 hrs
R: 36x300s + 60x180s - 5.5 hrs
G: 39x300s - 3.25 hrs
B: 32x300s - 2.7 hrs
