Cygnus H-alpha and Veil Nebula

Posted By Dave Erickson

Floyd, Rod, Thanks for the comments!

Rolando, Thanks as well. Yes wide field at the expense of resolution, to me its a good trade...

I have always had a passion for wide field, and have bumped against the laws of physics to put as much aperture as possible in front of short focal length systems. Funny that the real limitations aren't the fast optical designs but the physics of narrow filters and their restrictive acceptance angles.

I included an image of the moon with the Veil for scale

World's first International Dark Sky Sanctuary

Timely, I have worked yet another presentation to protect the dark skies in Kennedy Meadows 21.9 average moonless clear nights no light domes...I'll be in front of the Tulare County Board of Supervisors next Tuesday to defend the aesthetics of the night sky at this remote yet accessible CONUS site...

Around zeta Cephei

Posted By Dave Erickson

Hi Marciej,
That is very nice! There is a lot in this area that isn't imaged often including a planetary nebula near LBN457 that might be interesting at larger image scale.
Best regards,
Dave
