replacement Orion [previous one deleted].

Took this shot again. 8 x 50 secs, 50mm Yongnuo f/1.8 @ f/2. ISO 3200.
TWELVE of 20 subs discarded because of satellite trails.

Pretty nice, I reckon I can cobble together enough bits to mount my new cam on my unused ST80 so I was thinking about giving it a crack at widefield. Orion being the obvious and instantly recognisable target.

Cheers Paul; the field containing M8 and M20 is very good too, also the field
containing The Hyades and The Pleiades.

It's an interesting image from the perspective of relative brightness of the Orion, Flame and Horsehead nebulas and the missing fainter features like M78 and Barnards Loop. I wonder if an overstretch would bring out those fainter parts?

I wondered the same thing Tony. With the relative brightness of HH, you would have thought the loop would have shown its face.

From a pure DSO collection perspective if you lifted it all up and took out Rigel, do you think you'd get Rosette in the frame with M42 and HH&F ?

To add to your wondering, I actually considerably lowered the highlights in
order to quieten down the blown out core of M42 to allow its delicate colour to show through. Some of my Orion images do show a hint of the Loop, but
none show any sign of M78. Low and mid range Canon DSLRS are not among the best for Ha, but high end models do better. I might try some longer subs
and see if I can bring out the Loop, but I already use ISO 1600 and/or 3200
and f/2 or 2.8, so I will have to use substantially longer subs to have any
chance of bringing out the Loop.There was no sign of the Loop at any stage
of stacking/ processing of this image.

You could even include Rigel [just] with a 50mm lens if you put Rigel in one corner and The Rosette in the diagonally opposite corner, and
even include The Witch.
