Equipment Updates

1 05 2017
Musty rusty DS-10

Meade DS-10, purchased c. 1983. 10-inch f/4.5 Newtonian reflector on an equatorial mount.

As you can see, I’m still grappling with the beast, only now it lives in Massachusetts, not Indiana.

On our last truly warm day before winter, I took a wire brush to the rust on the exposed parts of the equatorial mount. The rust was mostly confined to the balance-weight shaft, but I brushed off some chipping paint on the post as well, then painted all the exposed metal with anti-rust primer. (Except for the tripod feet, they’re already good as they are.) I’ve been waiting for another warm day to cover that primer with black paint, but since one hasn’t arrived, it looks like my mount has a case of the rust.

That’s a new Telrad, by the way.

I’ve been contemplating building a dob box using Stellafane’s instructions, but I left many of my power tools behind in Indiana and I don’t really have the space to build a box. Or the carpentry skills, really. Anyway, I’m also thinking about buying a custom dob mount instead of building one.

I’ve got a new motor to install (still), but since I don’t do any imaging, it seems like more trouble than it’s worth. What I am going to get done, though, is stripping the gunk out of the focuser and replacing it with … what … lithium, probably.

Backyard Observing

New equipment bins on observing table, Catherine setting up her refractor.

Our last observing session was mostly Saturn, but Catherine also did a lot of double-star sketching with her 90-mm refractor. I’ve been trying to figure out a better backyard workspace, but mostly that means subdividing the observing table for task grouping.

I’m trying to keep the equipment budget low. Managed to get away from NEAF 2017 having only spent $120, and $20 of that was on a t-shirt. The other $100 was for a Celesteron alt-az tripod. I really needed something heavier (more stable) for the 15×7o binos, as well as for the 90-mm Mak that I like to take camping. I’ve been using the PST on a lightweight photo tripod, so this is a definite upgrade for solar observing. It’s a bit of an overkill for our birding scope, but we took it out to the heron rookery at Sleepy Hollow Cemetery in Concord yesterday, and it was light enough that I didn’t mind carrying it up and down hills.

I’m working on this summer’s packing lists. More on that next.

Charioteer’s Cross

6 01 2017

In the November 2016 issue of Sky & Telescope, Matt Wedel wrote about his observations of a crucifom asterism on the Auriga / Lynx border. I took a few minutes last week to sketch the field as seen with small binos (8 × 42s). I was unable to resolve any stars in NGC 2281, of course; it was more of a suggestion than anything when viewed with handhelds. My goal on our next clear night is to return to the view with the 12 × 70s on a tripod.

New England Fall Astronomy Festival 2016

8 09 2016

NEFAFNEFAF is back! The New England Fall Astronomy Festival is this weekend, September 9 & 10 (Friday and Saturday) at the Durham campus of University of New Hampshire. This year’s special guest and keynote speaker is Dr. Seth Shostak (SETI). He’ll be talking to students and faculty on Friday, September 9th at 1:00 PM in the Strafford Room on the UNH-Durham campus and also giving the Keynote Address from 7:00-8:15 p.m. at the Main Tent at UNH Observatory.

There are tons of activities on the schedule for kids (building rockets!) this weekend, in addition to lectures from notable amateur and professional astronomers aimed at the adults in the crowd. Don’t miss the Saturday afternoon discussion panel with John Gianforte (The Sky Guy), Dr. David Kipping, Dr. Seth Shostak, Dr. Suzanne Young, and Dr. Harlan Spence. And stick around: S&T‘s Kelly Beatty will be talking about the 2017 total solar eclipse. 

On Friday night, Joel Harris will give a tour of the night sky for novice observers. Marc Stowbridge will be giving the Saturday night sky tour. I’ve been looking at the sky my entire life, and I still haven’t gotten tired of listening to/watching sky tours. The UNH Observatory will be open, so this is your chance to look through a 14-inch telescope.

I’m reprinting the full NEFAF schedule here, but you should check out the NEFAF facebook page for more details.

Transit of Mercury

9 05 2016

The day started out a bit cool, with me running around the house trying to find a good spot to set up. Started on the front sidewalk, but soon moved to the backyard. Spent most of the day observing, punctuated with frisbee breaks. I wish I had sketched more carefully to capture the effects of Earth-Sun rotation.

Backyard. 130-mm reflector w/white light filter, Coronado PST.
