1st draft of M74

[Rocket Pooch]

I had a go at M74 but I haven't spent much time processing it, I will do this week, but here's the draft.

[Rick]

Did you mean to link to a .bmp file?

[Mike]

What are those wiggly things? Astro-worms??!!

[Rocket Pooch]

yes worms caused by the hot pixel and lack of dark and flats

[Mike]

I'm confused - how would that make things that look like worms?

[Rocket Pooch]

Because there's 80 of them connected together and there showing the PE of the mount, the reason why they go wiggly is because its in ALT/AZ config (no wedge yet).  If it was a GE mount they should be in a line, well nearly.

[Whitters]

Nice pic, I've got worms too! The option is either darks and flats as Chris suggested, or a soothing cream

[Rocket Pooch]

Ah ha,

Interesting this, after using flats and darks it seems there's ramdon noise from the gain setting on the SAC8, So I've tried a cople of options on M33 and M74 taken at the same time, I've also included a raw frams for John, he's allways surprised at the raw images.

M33 80 8sec
