NGC 6604

 This image of NGC 6604 was taken while I was traveling in Indiana. I have uploaded by starless and starred versions. Edge distortions of stars are visible in the starred version due to problems with spacing and the focal reducer. NGC 6604 is a cluster in Serpens and is an active, star forming region. 

Tech Card: WO GT-71 20th Anniversary Edition; iOptron Smart EQ Pro with 6A-II FR/FF; Mallincam DS10C imager; L-eXtreme filter. 168 x 35s integrations.

The Sun on July 8. 2022

 I have been traveling for a couple of weeks and I have returned to a cloudy, rainy, but warm NC. I did mange an image of the Sun though a gap in the clouds, and here it is. The disc shows several active areas which appear to be growing rapidly. AR 3053, towards the edge of the disc at the bottom, has the potential to produce M-Class flares.
