M101 - DSLR - 10" f/4

[themos]

This was taken over 3 nights, with 86 light frames of 300 second each, with a modified Canon 450D at ISO 800. The GSO Newtonian was wearing a Baader MPCC coma corrector and an Astronomik CLS light pollution filter. 18 darks, 32 flats, 24 bias. Tracked on the EQ6 with PHD2 off a CoStar on a TS OAG. Stacked in Iris, finished in PixInsight. One of the nights was exceptional in terms of focusing and guiding.

Great image! Lots of detail in the galaxy when you zoom in.
