IC434 Horsehead Nebula in Orion

[Fay]

I had a problem with this one, regarding darks & so i did not use any. I removed about 2,000 hot pixels in shifts!!!

28/12/11 21x600, QSI 583ws/Leitz lens @ F3.4, 7nm ha.

I wanted to get the HH in various ways, so this is number two. I also want to use a DSLR/SW120

Fay,

This is excellent, and a lovely FOV.............................................and it's in Mono.

Very nice!   The Horsehead has always been my favorite.

Good FOV and you've captured the dust rather well.

thankyou.

it could do with a crop at the top, but  i am thinking they are the orions belt stars, so left them in

Ditto, very nice

Why problems with darks ?
I thought with the QSI you could do them with your feet up in front of the fire

[Fay]

when i took the lights & flats they came out at 3292x2504, for what reason i dont know. the library darks are the correct size of 3326x2504.

So, i went into Maxim & did a new lot of darks, just for these subs, and they dont match up.

I took the lights & flats with Astroart & the new darks with Maxim.

I dont know why the darks wont work, as library darks are done at a different time.

I took them at the same temperature, but have big black specks everywhere.

Very good detail Fay, strange about the darks, did the flats work OK though?

I removed about 2,000 hot pixels in shifts!!!

How did you do that Fay?

I like the full frame with the belt stars, puts it in context.

Like it a lot, unusual field orientation.
