haven’t had the scope out in like forever (specifically since May) I decided to give it a workout since we have a star party over at the model train club on Wednesday. Just back from dinner with Mom and the family, I checked the skies – clear with a little haze and some passing puffball clouds) and set up in the back where I could line on Cassiopeia and most of the summer triangle. The tripod was as heavy as ever but everything went together well enough. Got out the seat and had a look.

First, ran a bead on the double cluster just to see if I could do it. Easy enough, and enjoyed just spending a couple of minute there. Then over to the coathanger in the triangle – I don’t know if I’ve ever seen it through the scope before, just the ‘nocks, so it was fun to find that too. Then I started poking around Vega – I’ve been looking for M57 for a long time and hoped to maybe spot it tonight. I did see a satellite cruise by which turned out (with some post-scope research) to be ENVISAT 1, a European climate monitoring sat. I think this might become a new phase of the hobby for me – spotting satellites and space stations and identifying them via the time and position I caught them.

At least that sure worked better than finding M57.

I might have found it this time, too, if it hadn’t been for that meddling humidity.  All I knew was that my glasses were steaming up. I’d lean back, taken them off and shake them clear. Then I’d put them on and in thirty seconds, I’d mist over again. It finally got so frustrating that I quit with only forty-five minutes of viewing. Annoying to get the scope out and get rooked out of eye-piece time.

I’ve since pulled information on M57 and will make a determined sweep for it next time the sky is clear and the temperatures a little cooler.

“Almost” Total Eclipse (8/21/2017) PDF Print E-mail

e were supposed to go up to North Carolina where we’d rented a block of hotel rooms for my mom, my sister and us. That was the plan. But then the cat’s kidneys eclipsed about two months ago. As she got sicker, we decided to cancel our plans. And as it always goes in astronomy (and life), she passed away between that decision point and the event.

That left us stuck in Orlando with an 85% coverage. Better than nothing.

We watched it through pretty dark glasses (no aftereffects while I type this (and I’m not blind) so it must have been enough). Wasn’t sure what we were going to get – driving rain about an hour before the event began. But yes, the skies cleared (and other than a little haze that did nothing to intrude) we were able to watch the entire run up.

Honestly, I didn’t know what to expect. I’m used to the popular image of a false night, the silence of birds, the stillness, the spreading gloom. Actually, when things got rolling, it was hot and muggy (Florida in August after a rainfall). We had to go in and get sunscreen and hats given that we’d be outside for a while. Outside, the sun slowly slipped behind the moon, turning into a pacman, a crescent, then the thinnest of underscores. But the weird thing was, no fall of night. No confused bats (or tricked, doomed vampires). I will admit that the air cooled slightly and the light took on a slightly subdued tone. My wife reports that she thought the shadows were deeper. I heard one night cricket rosin his bow and not finding his orchestra in place fall into an embarrassed silence.

But I was thinking that if you were about to be burned at the stake by medieval knights, you’d really have to point out what was taking place. It didn’t seem that great of change, not what literature had convinced me of. Even when gigantic weapons platforms silhouette the sun, the stars shimmer over the heads of the doomed.

I’ll have to ask those who went to the total totality if it was any different.

Jupiter as never before (5/27/2017) PDF Print E-mail

ate spring and summer skies are sucky night skies for astronomer. No Orion. None of the favorites. It's pretty much open space with few things to bullseye. But tonight was clear and Jupiter was on a close approach so I set up the tripod at dusk and waited for the gas giant to come into view.

Okay, first lesson learned - if you are aiming for something rising, don't set up in the middle of the yard. Set up to the west so you can catch things coming up from the east sooner. I could see Jupiter inside an oak so I had about 45 minutes of waiting. Still, I made the constellation Ophiuchus and checked out its anchor star, Rasalhauge. While spooling about, caught a satellite going by. Of course, with no watch it would be hard to figure out which one it was. No big deal.

So after a while, I picked out Jupiter through the last of the oak leaves. And it was well worth the wait. The first thing I noticed - all four moons were visible, clustered close (I don't think I've ever gotten four in the sky like that). It was clear and close, rather breathtaking. Walking up through the eyepiece power, I finally hit my max, 120x. Watch for a bit longer before I realized what I was seeing. There was a speck on the gas clouds, a "little black dot". I watched in for a bit, then went inside and spoiled my night vision looking it up (hey, it's Jupiter - it's like hunting elephants). Yes, this was Io's shadow's transit. The moon was casting its shadow on its owning planet. I've never seen that before and it was amazing to watch.

Also up, the eye (if my program was correct) was visible. I think I could make it out. I tried certain filters and convinced myself that that mid-band blemish must be the eye (Lowell haunts me still). But it was quite interesting, watching Io swing through its orbit. I stuck with it for about an hour.

Made Corvus low to the south and checked out Algarab, its high star. It was listed as being a binary and there it was - the second fainter star. Stepped up the magnification and inspected it - one bright, one dim. These new eyepieces are extraordinary - same power as before but a more comfortable and detailed view. I'm quite pleased with them.

Hunted around for M104, the Sobrero Galaxy. I have no idea what I was looking for but usually galaxies are smudges. Tonight the light pollution was pretty bad, so no sombrero. Still, it was a pretty interesting night. In ways, astronomy is like fishing - there is a lot of thoughtful reflection time while one waits for one's eye to sharpen. Overall, a good night. For a spring night.

New scope for the kids (4/27/2017) PDF Print E-mail

o my adopted daughter's kids loved looking through my scope in a backyard observing session a year back. Turns out my sister found an old, reliable (sorta) Meade, just a lightweight scope with simple knobs and a dodgy spotter scope. She got it for $20 at Goodwill (and if there is something the poor need, it's access to clear night skies).

Anyway, it was in pretty bad shape. Tonight I spent the evening cleaning it up, tightening the tracks (it's still a bit loose for my tastes) and trying to get the spotter to line up (never did). But with Jupiter back in the neighborhood and rising in the early evening, it gave me a perfect item to sight on.

So I looked for a while. Without the spotter, the smaller 9mm is a bit tricky to lock onto things - I had to manually sight down the barrel and do some fiddling to bring it into play (also, the scope still wanders). But Jupiter is such that even the weaker scope gives an eyeball a good run for the money. Even better, the Meade is lighter - I can carry it one-handed (unlike that Orion with the brick of a counter-weight - a two-handed puff-a-thon). Anyway, I think this should be a good scope for the three kids.

It might be a gateway scope to bigger things. They can thank me in twenty years when they’re swatting mosquitos and dropping lens caps in dark fields.
