Messier 45 The Pleiades. This was 92 minutes from Bel Air Maryland. I snapped 23 four minute exposures at ISO 400, 200mm, f/3.5 and No light pollution filter. Stacked in Deep Sky Stacker and edited in Adobe Lightroom and Adobe Photoshop. At 200mm focal length the cluster is quite small, so this has been considerably cropped. I chose this focal length because it enabled me to shoot at f3.5 which would give me over 8x as much data in the same amount of time. My alternative would have been 400mm @ f8. Not only would the lens pass ½ as much light though at f8, but it would also be spreading the nebula out over 4 times as many pixels. Thus resulting in 8x less light hitting each photo diode on the camera sensor. Now to my advantage I had great weather this night. It was party to mostly cloudy all over Maryland and for whatever reason, the entire time I was imaging I was under a hole in the clouds giving me exceptionally darker skies since the clouds everywhere else were holding down the light pollution. I did not use dark, bias, or flat frames to create this.

Tears of Pele -
It has been a dream for three years. To finally return to a volcanic eruption. To get back there with proper gear, proper experience and courage. And drones. Ever since the Holuhraun eruption I fought with myself - back in the days I was not prepared. I did not have the right gear (yes, sometimes gear matters), I did not have the right experience. My old Phantom 2 was just not on top of things to capture this event adequately and I was not couraged enough to risk it all.
