Only got a short period between clouds and rain.
EQ6R, skywatcher quattro 250 F4, canon600D unmodded
BYEOS, DSS, Startools
85x1min lights, 25 each of D, F, DF, B
Layered with 25x 5 sec lights to try to preserve core/trap
Thanks for looking, comments, advice.

PS photo is upside down. Won't rotate?
PS photo rotated back to upright with startools, thanks Martin and Nick

Rob,
That’s a nice image of M42 with a 600D ( I used the same camera in my Newts for many years )
Well done !
You should be able to use Rotate in Startools to flip the image ?

Cheers
Martin

You should be very happy with that. I use Gimp (free software) and it will flip your image; I just tried it. I'm sure a lot of the photo editors will do that. I'm hoping to get a couple of hours tonight. Keep up your good work. Cheers, Nick

Rob, that's a great result with a DSLR. Your unmodded camera has captured nice colour and detail. In fact, I reckon with a little increase in contrast (which I did to your image just to see what could be extracted) you have almost matched Strongmanmike's redition of the core posted in the Deep Space forum. Colour and detail were almost identical. That 10" light bucket you have has been tuned to perfection. Top job! :thumbsup:

Thanks, Martin and Nick. I was able to rotate the image with windows photo, but when I posted it to IIS it would derotate back to the upside down position. I rotated with startools and that loaded to IIS in the correct position. So I replaced the upside-down photo with the correct one.
Thanks Michael, I will try to increase contrast and see what happens in startools. Rob

Thanks John.
Michael I tried a bit more contrast and sharpen in startools, attached
Not sure how far I should push this. Rob

Very nice image! Define upside down. Your previous image was correct when Orion is in the west. The rotated (current) image is correct with Orion in the east. This for observers at mid southern latitudes. I like Iota Orionis at top right With M42 nebula ‘blooming’ to upper left which is your image rotated 90 deg. anti-clockwise. This equates to Orion in the north for southern observers.

There is back-to front (reversed) which your image is not. This is caused by an odd number of reflections in the image train. Seeing images of planets (or star fields) back to front is not ideal when trying to compare to a map of surface features. It’s not that difficult to reverse the image and most image software has this feature.

Anyway, I digress. Very nice image from a DSLR. Well done!

Just repeating what everyone else has said - a great image and well done!

Rob I was referring to the core in regard to contrast. The remainder of the shot will suffer if contrast is applied overall. A mask would work to increase contrast (a little) around the core and protect the rest of your image.

Great image, Rob. The colours you’ve captured are very really appealing as is the detail. Alex

Thanks Steve and Alex. Michael, I tried another bit of extra contrast and sharpening in the core with a mask and I think it is better but may be difficult to to see in the attached compressed picture. Rob
PS astro 744, I think I am just used this orientation of the photo.
