First Images of Comet NEOWISE

Early this morning I was able to capture some initial images of C/2020 F3 NEOWISE.  I had provided some charts in my previous post and with NEOWISE only getting about 10 degrees up in the NE there was no chance I could image it from my home. So I packed up my Canon 70D and headed to my church property in Westminster. I decided against bringing my portable telescope figuring I try with just the Canon on a tripod and see what I could get.

The first photo is a composite (stacked) image of 10, 2sec exposures, at a high ISO value of 3200. The Tamron 18x270 lens was set to 77mm (I had wanted 100x but somehow the zoom slipped) at f/5.6.

The second is a composite of 10, 1 sec exposures at ISO 1600, 270mm, f/6.3.  Since these exposures were taken rather late, the sky had brightened considerably. Lens fogging didn't help either!

Neither set of images were processed to eliminate/minimize noise, so they are a bit noisy.

Plan is to take a few more later this week, potentially Saturday morning, weather permitting.  Then, when NEOWISE makes it to the evening skies, I'll image with the either the GT102 or the EdgeHD11.
