Crab Neb and a dark cloud in the Hyades

2 nights ago got just 15 mins on the Crab Nebula M1 before cloud came in.
3x5 mins ISO 400. LPS filter, MPCC , 6 inch f3.6 Sn. Modded 350d. First quarter moon in sky. 2nd pic is a full resolution crop. Taken on a warm night

Last night did 70 mins on a little known dark nebula area in the Hyades. Id recently seen Theodog's (Jeff's) 12 inch shot of part of it. The lack of stars shows where the nebula is, there is also the part Jeff imaged, a small HA area only just visible inside the dark area upper left. Terrible conditions for imaging, brighter then first quarter moon and a warm night. Im lucky I got anything, but I was keen for imaging There is a screenshot from Star Atlas pro of the area.

Great shots Scott.
I had never heard of the dark nebula in the Hyades, yet alone the Ha region.

Your image certainly shows it in perspective.

Well done.

Thanks all
I wish I got 70 mins on the crab instead of only 15. I will try again when the moon is gone.
I jagged polar alingment well too. I used the portable mount to set up from scratch in front of the garage where I get a good north view. I was polar aligned by dark, using drift method for both azimuth and altitude. The Q guider picks up stars well before dark. Also Ive got the mount setup so that when the lost is perfectly vertical using a spirit level, altitude is very close.

Polar alingment turned out to be so good no dec adjustment was necessary during the 5 minute subs, so in essence I didnt touch the dec control during the imaging run.
Looks like no more imaging till after full moon now
