If you're looking for my old Astro Journal (more than 5 years ago) with my Equipment and Astro Automation pages: https://SaltwaterWitch.com/astronomy
Some of my gear:
I'm going to start a series of posts on this topic--"essential tools" to showcase a batch of tools, components, and other products and items I use to make this whole astrophotography journey easier. The first three are must-haves in my book--links below.
1. Slip joint pliers with plastic inserts, designed for jewelry making I think. These come in handy when you need to tighten down the knurled metal screws for guide camera rings, or holding the guide cam shoe, or for tightening the tensioner on a rotator. These might work in cases where you want to tighten something just a bit more than you can with your fingers. But you also don't want to scratch the metal, paint, or plastic of whatever you're tightening. Just be careful because these are still regular pliers and you don't want to break anything.
2. I use nitrile gloves every time I'm changing filters, adjusting spacers or the OAG, and doing just about anything with my cameras. That's an obvious use, but I use these instead of the ring clamp tools I usually see as "must haves". I use these when I need to remove filters and spacers that are stuck, and the gloves allow you to unstick these without applying a lot of pressure, without squeezing one side of a spacer so much that the adjacent sides bow out and make it worse. They're even grippy enough to unstick those pesky super-slim M42 to M48 spacers.
3. Real gaffer tape, the expensive cloth stuff that will hold things down but won't leave any residue. Get the real thing, not the cheap stuff. I use this to hold cables together, to tape cables to the mount or the side of a camera. It's as permanent as you want it to be, holding whatever you need to hold until it's time to tear down your gear. Then it just peels away, and you can reuse it.

So, I've been goofing around with hardware, updated NINA and plugins, getting ready for the next clear night. It's raining right now. I was looking at some narrowband data for Sharpless 2-199 (Soul Nebula) I captured late last year and reprocessed the Ha data. I am especially fascinated by the differences in depth and darkness between the background and the bands of dust and interstellar gasses that twist in front of the Soul Nebula, between us and the high-energy emission of the towering clouds of hydrogen beyond. Someone commented (I think on AstroBin) on another image of mine with similar properties—that I needed to bring up the black point, that the night sky is black. But why? Who says so? The data says the background isn't as dark as the dust, so why would I want to lose that difference?
I've been thinking about portability for a while, but of course that was on hold for a couple years. I'm thinking about it again. We have pretty decent night skies here, somewhere between bortle 4 and 5. On a clear night with good seeing, Andromeda is easily visible, the Milky Way isn't super obvious but you can see it--and it's easily captured with a 10-second exposure on any camera. We have great views of the circumpolar constellations, and there's so much to image in Cepheus, Cassiopeia, and Auriga. Just these three contain some of the most beautiful nebulae in the night sky. So, not bad at all, but being so far north (+43° Lat) we're also missing a lot of great nebulae around the galactic core.
For that, we will need to go south for some imaging.
Here's a shot of a nearly full moon through the trees. I also wanted to capture the moonlight through the glass insulators on the transmission lines. About a third of the way in from bottom left is the variable double star Antares (α Scorpii) in the constellation Scorpius. Antares is also part of the Rho Ophiuchi Cloud Complex, one of the most colorful and beautiful regions in the night sky. Unfortunately, what you see here, Antares at 20° is about as high as it will get in the sky. We're just too damn north.
I'm selling my Orion Atlas EQ-G Mount and Tripod. This is a complete astrophotography setup with serial to USB cable as well as the Shoestring Astro BT2EQ6 bluetooth module for connecting wirelessly to the mount from a computer. The mount is in very good condition. There is some minor wear along the saddle where I have clamped on my scopes. Shoestring Astro BT2EQ6 bluetooth module supports ASCOM and INDI for mount control, or use the included USB2EQ6 Interface Cable that will run from the mount's serial port (DB9) to a USB port on your computer or astro controller. Setup manual for the BT2EQ6 here: http://www.store.shoestringastronomy.com/User_Manual_BT2EQ.pdf
Local pickup would be great. I can meet you for delivery in the Exeter, New Hampshire area, or in Danvers, Massachusetts (north of Boston).

Here's the Atlas in action:
The famous "Pillars of Creation" from the classic Hubble (HST) image are in the core of the Eagle Nebula (Messier 16). It's no Hubble image, but still crazy what I can capture with a 250mm refractor from my backyard in New Hampshire.

Holy Rutting Poseidon, the pronunciation of the constellation Canes Venatici in English is an abomination (From wikipedia: /ˈkeɪniːz vɪˈnætɪsaɪ/). Seriously, you're telling me the accepted pronunciation is Kay-neez Ven-AT-i-SAI? The old ghost of a classicist in me (although more ancient Greek than Latin) really wants me to go full Latin, something like Kahn-ess Wen-a-teekee, but Venn-ah-TEE-see sounds great, or even Venn-ah-TEE-chee. Canes Venatici is Latin for "hunting dogs". We don't have to go back that far, but why aren't we pronouncing it to something closer to Latin? There is no way in hell it should be pronounced Kayneez Ven-AT-i-SAI. Who is to blame for this barbarous pronunciation? No, seriously, I'm asking? Now I'm thinking "wikipedia" is supposed to be pronounced Why-kuh-pi-DIE-uh. That makes about as much sense.
In two parts: I spent the first half of the night on IC 1318, the "Sadr Region" at the heart of the constellation Cygnus. IC 1318 is a vast and energetic emission nebula surrounding one of the brightest stars in the night sky, Sadr (γ Cygni). Click for the full sized image.
And then shifted the whole operation to the south to the constellation Serpens, just out from the Milky Way core, capturing Messier 16 (Eagle Nebula, NGC 6611), the bright nebula on the left side, and M17 (Swan Nebula, NGC 6618) on right.
