I posted this image a week ago but I shot another couple of hours of it and have now added it to the original image.

It is now 4 hours worth. LRGB 60 60 60 60.

FS152 ST2000XM.

Greg.

The data looks great Greg! It is a little too bright on my monitor, but I think my monitor is naturally too bright. I sure wish I had your dark skies. I am envious! wink

I ended up using less of the shots as they weren't all at the same orientation. A lesson for next time.

But I did flat field the previous shots and it made a big difference. This is the final processing on this (up to about 12 hours of work now!).

I was able to process the faint nebulosity surrounding the Trifid which is not normally seen. The faint blue nebulosity extends to virtually the entire photo. This Tak FS152 scope enthralls me. It is truly a delight.

I have noticed in a number of the images from my rural site that there is more to the object than normally seen. I put this down to the excellent optics on the Tak scope and the magnificent skies there at Bigga. They are stunning.

Well Tyler, send me an email if you come down to Oz and I'll take you there.

Cheers,

Greg.
