M81 & M82 - Bortle 6

[Aramcheck]

From last Saturday night. Only managed 104 x 60 sec subs (200dps + EQ6 + Canon 600d) as had a few hiccups including narrowly avoiding the scope hitting the tripod & getting used to controlling the mount via APT/Stellarium on a laptop.

One image shows the light gradient of the stacked image, with just the initial colour cast from the DLSR removed. I find it difficult to get an even background level from this data, which I guess would need longer exposure time to improve on?

I'm processing in Pixinsight & after DBE found the Masked Stretch process worked better than the STF + HT combination.

Cheers
Ivor

Very good.

I think it's Richard Bloch on YouTube has a few good PI tutorials.
