Default ASTRO: two from last night

from the backyard using the 18", cs 4.5ha filter, cm10 and the geg/reducer

all subexposures were 30 minutes

I think the crab was 8 x 30 minutes of good exposures and I got 7 for the
bubble if I remember correctly

I'm not far off if that's not right though

Richard -

Do you happen to have a NB color image on M1?

Thanks for the links - very interesting.

I did some NB imaging imaging a year or so ago. M1 seemed too harsh
in NB so concentrated on emission types.

maybe I'll dust off the filters and give it another try.

Two very good detailed images. I'd wish that M1 was near the celestial north
pole, then my mount could handle imaging it at f/10.
