Orion the ol' petrol head


Recommended Posts

I finally had a 'clear' night, so at least there were no clouds present. Just the smog.

I gave The Orion Nebula a go, as a first proper run of the 1600. The mount did what it was meant to do, so no issues there. I also put the APCCD67 back in the draw tube, ending up with a reduction to f5.8, and I removed all filters - no IDAS, no IR cut.

All is not straight in the RC, but I'm getting there slowly I think.

Last year I did a bubblegum Orion, and this time I tried to keep the saturation down. I don't know if it's perhaps too muted and dull in this 'rendition'.

It's a bit bright to the left, and dark to the right. I wonder if that is due to reflections from the building, lack of IR filter or if the region really is a bit brighter there.

2 hours 8 minutes. 4 minute subs. No layers. No NR. (Yet :smiley: ).

A 500s guide graph looks like this: (You can see the dither jump in RA)

And the nebula, rich in Ha and petrol fumes looks like this:

Thanks for looking!
