Milky Way 20180707
Our galactic neighborhood in 13 stacked 15 second exposures, Nikon D750, Rokinon 10mm f/2.8 lens. What's crazy is this with a decent DSLR camera, lens, a tripod, and some free image stacking software (DSS). I did the stretching in Photoshop CC--"stretching" is when you adjust contrast, intensity values, to bring out the features of whatever you're shooting--in this case the north end of the Milky Way Galaxy, our home. Let me point out some interesting features: starting at the left, that vivid red star is the "Garnet Star" (Mu Cephei), and that's right next to some cool nebulosity that includes the Elephant's Trunk Nebula (IC 1396), a little ways along, you see that blocky reddish region? That's the North America Nebula (NGC 7000) with the star Deneb (19th brightest star in the night sky). Deneb forms the northernmost (leftmost in this shot) point of the famous "Summer Triangle". The other two points are Vega, the 5th brightest star in the night sky (to the right and above the Milky Way core in this shot), and Altair (12th brightest) a little more to the right and below the Milky Way core. Moving along the galaxy, just left of where the powerlines cross, those grayish-pink cloudy areas? That's where you will find the Eagle Nebula (Messier 16, NGC 6611) and the Swan Nebula (M17). That bright point of light in the middle of the powerlines is the planet Saturn, which is moving along the ecliptic and right now it's in a pretty good place for viewing. Just right of that are a few more cloudy areas. That's where you would look for the Lagoon Nebula (M8, NGC 6523) and Trifid Nebula (M20, NGC 6514). Somewhere along the Milky Way--this is where you will mostly likely find me focusing my telescope all the through the summer and fall. I almost see this shot as a map of places to visit from afar, and the cool thing is you really don't need to setup the astro gear for this. You can create your own galaxy map, as long as your camera can handle long exposures (only 15 seconds) and you have it on a tripod with a remote shutter control. SaltwaterWitch.com/astronomy

Eagle Nebula in Ha and OIII
I was out last night with the William Optics ZS61 and Atik Cameras 414EX, doing some narrowband imaging. The Eagle Nebula (Messier 16, NGC 6611, Star Queen Nebula) is an open star cluster and emission nebula in the constellation Serpens, about 7000 lightyears away from us. Imaging Info: 96 x 240 sec. Ha + 41 x 240 sec. OIII frames stacked in DSS, processed in PSCC2018. These frame numbers are a bit unbalanced, but the clouds moved in during the OIII sequence, and there was nothing I could do. I went ahead and stacked and processed them as they are. I'll probably come back to this one in the future with more oxygen-3 (and maybe sulphur-2) to achieve something like the actual proportional levels of light from the nebula across these bandpasses. Equipment: William Optics ZS61, Atik 414EX mono CCD, 12nm Astronomik Ha filter, 12nm Astronomik OIII filter, CEM25P EQ Mount, ZWO ASI120MM-S Guide Cam + Orion TOAG, INDI/KStars/Ekos control software. Location: Stratham, New Hampshire, Bortle: 4, SQM: 20.62

Cygnus Wall NGC 7000 Ha-OIII
The view from my backyard, with the right equipment focused on a particular part of the sky: Cygnus Wall region of NGC 7000, the North America nebula, imaged in narrowband Ha and OIII. The way narrowband imaging works is by filtering out all light except for an allowed narrow bandpass at specific locations in the electromagnetic spectrum. A hydrogen-alpha (Ha) filter will only allow light to pass through to the camera sensor around 656 nanometers, which is out at the red end of the spectrum, and an oxygen-3 (OIII) filter will only allow light to pass through around 501nm, which is in the middle of the blue and green ranges. When I say red, green, blue, I'm talking about where these bandpass lines fall within the scope of the visible spectrum, which starts around 390 and goes to 700 or so (for humans). I shot the oxygen-3 sub-exposures last week, and the hydrogen-alpha subs last night. When you process these separately filtered images into one color image, you may get the Ha coming out vivid red to rust red, and the OIII coming out in blues and greens. The Cygnus Wall is that bright, rolling line across the middle where you have a lot of concentrated star formation, but this area of NGC 7000 also has lot of dust and debris drifting in front of it--the dark reddish-brown regions across the top and right side. (Imaging info: 42 x 300 second subs in OIII, 40 x 300 sec. subs of Ha. + 20 dark frames stacked in DSS, processing in PSCC2018 + Astronomy Tools actions & Annie's Astro actions. Equipment: William Optics ZS61, Atik 414EX mono CCD, 7nm Optolong 2" Ha filter, 8.5nm Baader 2" OIII filter, CEM25P EQ Mount, ZWO ASI120MM-S Guide Cam, SaltwaterWitch.com/astronomy).

Crescent Nebula NGC6888 Ha-OIII
The Crescent Nebula (NGC 6888) with two channels, hydrogen-alpha and oxygen-three. 4 x 1200 second exposures for the Ha (mostly red channel), and 10 x 600 second exp. for the OIII (mostly blue channel). I didn't get nearly enough of the blue halo around the Crescent as I would have liked. I'll probably need to go to 20-minute exposures in OIII next time--or more 10 minute ones.

I'm a fairly creative guy with a pen and a paint brush, author of Seaborn (Juno Books), Salvage (Masque, 2013), Nanowhere, and a shelf-full of other books. My short stories have appeared in a bunch of magazines and anthologies, including “Lost Dogs and Fireplace Archeology” in Fantasy Magazine, and ‘Tear Apart Worlds” in Pen-Ultimate. My story “Hammers and Snails” was a Robert A. Heinlein Centennial Short Fiction Contest winner. I write and illustrate the comic, Saltwater Witch. My ink work and digital illos have appeared in Shimmer, BuzzyMag, various RPGs, and on the pages and covers of books, blogs, and other interesting places. Last year I painted a 9 x 12 foot Steampunk Map of New York for a cafe in Brooklyn.

Two new pages up for SaltwaterWitch Comic 16!

This set features the start of an intense discussion between Kassandra and her grandmother--Kallixene. Even with Ephoros at her back, Kassandra's on thin ice, not certain about which direction to go with her new-found family.

May great rulers, just and wise, summon you to appear before them so that they and their cheering subjects may honor you this year.  May joy and friendship support and richen your merry-making, and visions of glorious color and sophistication lurk ready at your calling to assist you in your art and help you lift the world's spirits with beauty, enhanced and shared.  May every sun that sees you this year rejoice in your happiness, may a year from today find you wiser, happier, more skilled, and rejoicing at the thought of another HAPPY BIRTHDAY!
