Image
8 subs of 2 minutes 35mm f/2 ISO800 with H-alpha filter on modified 450D.

Was just browsing the last-minute data captured in the last night imaging session. This was just as cloud was moving in so the contrast sucked anyway. I'm still amazed what details you can pull out of bad shots. This is a wide area shot around Orion. You can easily see the flame, horsehead and great nebulas surrounded by the loop.

But what is that splodge far on the left edge of the shot??? From the relative position I'm guessing it's the Rosette nebula? Wasn't expecting that at the time!

Oh, the mess down the bottom of the shot is what I have to deal with from my observing position. The glow is from the Christmas lights of opposite neighbour. The dark splodges with lines are obstruction by treetops. I don't have much freedom of movement in viewing spot without going far from my house. The great nebula would just clear the treetops and worst light pollution if I target them with longer focal lengths.

Hi popo,

I reckon it's the Rosette Nebula as well. Aren't serendipitous discoveries fun! 8)

It think Bob is right. Do you Stellarium? A great tool for seeing whats about at night in each direction.

It is the Rosette nebula as I have since gone back to image it, and have posted it elsewhere in this subforum :)

In fact, weather allowing this weekend I intend to revisit this. Tempted to last night but I was out for most of it.

I'm jealous as my D200 doesn't do a good job at picking up the Ha. Good luck!

The other thread I did was here. That was only Ha. Part of me wants to see if there is anything else I can add!

Forecast for late tonight is interesting, and tomorrow night is currently indicated as promising...
