Orion Mosaic: I’ve had the Atlas EQ-G mount, William Optics GT81, and ZWO ASI071MC camera set up for the last three days. It’s been cold–down around -10C in the early morning hours. With a new moon that’s slowly waxing, but still mostly absent from the night sky, I’ve been using the color camera to capture some amazing targets, including this three panel mosaic of the Orion Nebula (M42), Running Man Nebula, Horsehead Nebula (Barnard 33), Flame Nebula (NGC 2024), and the three giant stars in Orion’s Belt, Alnitak, Alnilam, and Mintaka. This is why the Orion Constellation is arguably the sky’s most impressive constellation. NOTES: 31 x 300 second exposures for each, with an additional set of 10 and 30 second exposures for the Trapezium in M42–that really bright triangular region. There’s just so much fiery star forming action at the heart of the Orion Nebula that any exposure over a dozen seconds is going to blow out the whole area. https://SaltwaterWitch.com

Comets December 2018
I didn’t just take some shots of comet 46P/Wirtanen last night. I also captured comet 14P/Wolf as it passed by the blue giant star, Rigel (the lower right star in Orion). I posted some time lapse shots of both on youtube.

I caught Comet 46P/Wirtanen in one 240-second exposure as it was passing through the constellation Eridanus. Next week 46P will pass about 7.2 million miles (0.0774 AU) from Earth, it’s closest approach for the next 20 years.
