M8 from my observatory..

..in the city, last night, overlooking a brightly lit Home Depot parking lot, during a scorching Midwest summer night, thru thin clouds that glowed like Gotterdammerung. Thank goodness for narrow band H-a filters! Unguided I might add since I could not keep a guide star going thru those clouds that continually swept thru the field.


6 x 5 minute exposure thru Baader 7nm H-a filter, 175EDF refractor working at F6 with TCC telecompressor, STL11K camera.

Hi Roland, Very Nice. There is hope for those warm moon-HomeDepot lit summer nights. Sure beats reruns on TV. Any idea of the SN you are getting, or integrated sky brightness?

Regards,
Dave

Amazing amount of dat for such a short amount of time! 8O

Nice result Rolando. Is it time to disassemble and get the surfaces coated? You might want that extra 25% or so when you go after the dimmer stuff.

...and nicely processed too. M8 is another that is a challenge to hold down those really bright areas.
