Orion Trapezium G and H?

[beka]

Hi All,

This is an image of the Trapezium in Orion taken with my CPC 1100 and  Canon 700D. 21 x 15 second exposures at ISO 400 were stacked and auto-stretched in Siril. Curve was tweaked, image was sharpened and cropped in Gimp. It was taken at the native f10 without a focal reducer. The stars are somewhat oval - the reason for which I have not figured out. I think the G and H stars can be made out. Hope you like and any comments are welcome!

A nice revealing shot.  I agree F and G are visible.  Considering the focal length of your set up the stars are pretty good in my view.  How is you CPC mounted?

Nice shot. Yes, E & F (just) are visible, well done

Hi Owmuchonomy, it is on the factory altaz mount.

I have edited my original post, E and F stars are clearly visible. I had meant to say G and H stars. I think both of these are visible if you zoom in to the full sized image.

It's possible, they are pretty faint. I've marked the positions here.

In that case I think your stars are a very good shape for a non EQ set up and long FL.  Well done.  I think the target is almost overhead for you in your region?

I agree you have A to H.

Nice work!

[Moonshane]

Actually H1 and H2

At the time it could have been 50 to 60 degrees - can check the exact time. Seeing was not the best I have experienced.

I did another run at processing. This time I stacked just 3 of the images with the roundest stars and sharpened more aggressively in Gimp. I believe now I also managed to snag the "I" of the trapezium with G and H becoming more obvious. I don't think H1 and H2 are resolved, rather we see another star near H which does not seem to have a similar alphabetical designation. 

Wish everyone a happy new year!!!
