ASTRO: M20/M21 from AP180EDT & PL39C

this is 7 hours 15 minutes total. it was taken the last two nights from my
ranch in the Sierra foothills

the exposures were all 15 minutes: 29 total.

the full rez image is sort of fun :-)

The AP180 is a simply stunning performer with this huge chip ( 49 x 36.8mm,
39 mpixel @ 6.8 micron pixels)

it looks like 10-12 hours will make for a very nice image. That seems to be
about what it takes using LRGB from what I have observed in the better
images but maybe no?

Hi Richard;

Stunning image.

Any idea what the horizontal streak is near the bottom right corner?

It's easiest to see with the high def version.

Thanks

oh that is an off axis star reflecting off my field flattener mounting ring

I need to flock it or spray paint it flat black

Great picture Rick,

I am still loading the 39mp version ;-), but the 6mp looks very good, don't
see that it needs additional time.
