Some Ursa major (or close to) galaxies

I managed to take some shots of M51, M101, M109 and NGC 4088 (complete with supernova) last night.
Here is my attempt with M51 and M101

M51. 20 x 60 second exposures at Iso 800

M101

9 x 2 minute exposures at ISO 800 stacked in DSS

There is virtually no extra processing apart from trying to darken out the vignetting. My attempt at taking flats failed miserably.
I am impressed with the mount though. It can just take 120 second exposures at prime focus unguided and no PEC without significant star trailing. Having an accurate Goto makes imaging these faint fuzzies much easier as they ae not visible in the eyepiece where I am living.
More to follow.....

Bit of processing on M101

Well done John, I like your M51.
Is that the CGE mount your talking about?

Hi John

It's a CGE mount. I am still learning how to set up the PEC correction. It should give me a few more minutes without the need for guiding.

Hi John,
Those are grand images, you're really coming long with this mount.

Thanks guys

Here is my attempt at M109
