NGC 7331, a quintet, and tilt

Recommended Posts

My first astro image for the season. Last week we had a few hours of astrodarkness and clear skies, so I snapped this image of ngc 7331 and Stefan's Quintet. The atmospheric conditions were rather mediocre (guiding about 1", and the autofocus routine also reported high HFR values).

I have tilt in my focuser, but as I have a FeatherTouch incoming, I won't remedy that now.

This image is only 10 x 300 s G and B, and 15 x 300 s R, with a synthetic Luminance.

Gear: SkyWatcher 190MN on an AZ-EQ6 mount, ZWO ASI294MM camera at -10 C and 0 gain

Really nice Wim with these two galaxy groups in one frame and I am not bothered by any tilt as I cannot see it at the image scale you present it (and I have a 44" monitor).

Thanks guys. Glad you both like it.
