Scorpius Region

By golly, this was from last year, a series of 5 frames that I did not want to process because it needed flats in addition to dark frames. But I've been shut in becuase of the weather, so here it is, showing just a hint of the rich nebulosity around this region. Those with modified Canons will do much better at bringing out the emissions. As you can see, I should be using a flat frame in something like this that is processed to the hilt.

Scope: Tak Sky 90, reducer, Canon 20D. 5x 6min.

And here is the completely over the top processed version.
OK, you guys with the modified cameras, have a go at this in 2 months!

See that big old yellow band down the middle?! Need flats.

I like it Ivan! Love that field of view in the Sky 90. Memories of 'scopes since sold. I regret selling my E130 and vow to never sell another Takahashi 'scope I own.

Did you notice in Klaus' latest post how the modification didn't seem to flood the image with red nebula but rather produced a more balanced look? Could be processing or exposure particulars I guess but the 5D modified is a contender I think.

Nice shot, Ivan, but I don't think a modified camera will help a whole lot. Most of that region is filled with reflection nebulae that are blue or orangeish yellow, and there is not much in the way of emission nebula.

Check out this image to see what I mean. This was taken from New Mexico Skies, where it's VERY dark, at new moon, on a very clear night, with an STL-11000XM--more sensitive than even a modified 20D or 5D--and is 30M Luminance and 10M each color. Still not long enough of an exposure to really get everything.
