Total Solar Eclipse of August 21, 2017

Posted By Linton Rohr

Howdy folks,
Two years from today! Where will you be? 8)
I'm wondering how many of you have already made plans for The Great American Eclipse of 2017.
I've been writing a casual stargazing column for our little local newspaper and wrote up
the article pasted below to try and stir up some area interest.
Researching and writing about it have really got me excited! grin
Anyone else?

Insider Stargazing Tips

Total Solar Eclipse of August 21, 2017


A total eclipse of our sun occurs only two years from tomorrow. The rarest event in sky watching. The last one visible from the ‘lower 48’ occurred in 1979. Astronomers and sky watchers have been talking about it for several years. Many have already booked motels along the path of totality. So, no, two years is not at all too far ahead to plan!
The extraordinary event begins in the Pacific (imagine that sunrise!), comes ashore on the coast of Oregon and stretches all the way across the country and into the Atlantic at South Carolina. The long (but narrow) path of totality, combined with favorable weather and easy access for millions, have prompted eclipse enthusiasts to dub this “The Great American Eclipse”. And it truly is an American eclipse – the moon‘s shadow will only touch mainland U.S. soil. The last time that happened was June 13, 1257 and it won’t happen again until January 25, 2316!
“Eclipse chasers” from all over the world will be here to see it. Most of them will tour part of our country before settling in at their chosen location. I’m betting that Wyoming, Idaho, and Oregon will attract a lot more solar tourists than Nebraska, Missouri, and states to the east. Jackson Hole may be one of the most popular places of all. Which is why I think I’ll avoid it.
A scenic location from which to view, certainly sounds appealing. But aside from being absolutely certain that you’re in the path of totality, the next most critical consideration is… the weather. There are maps online, which indicate the likelihood of clear skies in any given location on August 21 of an average year. Eastern Oregon, for example, has much better odds than the coastal region. But you know how things can work out, when you plan so far ahead. Murphy’s Law has to be considered. Contingency plans must be ready to implement if unusually cloudy weather moves in on your chosen location.
An internet search of ‘2017 solar eclipse’ will provide a wealth of information. Find a couple websites that you’re comfortable with. ‘Eclipse2017.org’ is one that I can recommend. And start planning. Now.
“So what’s the big deal?” you might ask. Didn’t we just have a solar eclipse a couple years ago? No, not like this. Not a TOTAL eclipse. The annular eclipse on May 20, of 2012, was really impressive to see, but only hinted at the awesome spectacle of a total eclipse. The difference is like, well… like night and day!
We’ll literally see day turn to night in a matter of minutes. Orion and the stars of late winter and early spring will come out. Venus will be visible high in the sky, which is normally impossible. And as the last thin crescent of sun disappears, the corona appears! A truly astounding phenomenon!
For the brief couple minutes of totality, all the eclipse glasses and special filters (that you MUST learn about and USE) can be set aside. Your eyes can safely view the corona, though your mind may have difficulty believing what you’re seeing. I wouldn’t even bother messing with a camera… the time is far too precious. There will be plenty of pictures online to look at afterwards. But the precious memory will be seared into your brain forever.
You may have seen an eclipse depicted on film, if you saw the 1962 biblical classic ‘Barabbas’. The crucifixion scene was delayed in order to be filmed during a total eclipse in Italy. This was, of course, before modern day special effects and computer wizardry, and was filmed in one take. Awesome! You can watch it on you-tube, if you search the keywords. If anyone here has already seen an actual total eclipse, I’ll be a little surprised, very impressed, and I really want to hear from you.
Only a very small percentage of humans have ever witnessed this amazing phenomenon, but those who have, swear that it’s the most incredible thing they have ever witnessed. This will be my first. I sure hope you’ll join me!

Seasons Greetings!
I came across this touching video on a local astronomy forum.
I really liked it and thought it worthy of sharing here.
Technically, it's a Christmas ad, but it sure doesn't feel like it.
Merry Christmas!

What size 2" eyepiece should I get first?

Posted By Linton Rohr

Hey David,
I've got a Meade 8" (LX-90), so our scopes are similar. (It's my first.)I think you want to start WIDE and then work back to higher power.
I couldn't see forking out the bucks for the 35 or 41mm Panoptics, so I opted instead for a Meade 40mm Superwide. It will provide BIG views of the larger open clusters, nebula, and the Milky Way starfields.

Next, I added a 27mm Panoptic. It's definitely a sharper ep. Still a wide fov, but with a bit more power . It brings in sharp images of many nebulas, open clusters, and galaxies. M81 & M82 fit nicely in the fov.

I'm thinking about a 20mm Nagler T5 next. 20mm is the theoretical sweet spot for our scopes. (Focal length divided by f/#).

By the way, if you haven't already purchased your 2" diagonal, I'd recommend the William Optics unit.
It's a great value.
Have fun shopping!

My much awaited test of the Radian EPs.

Posted By Linton Rohr

Hello Floyd,
I'm jealous - I have been hoping all summer to get my scope (and myself) up to the Owens Valley and the Sierra. I'm just curious how far North you were. Lone Pine, Bishop? The elevation is about 5000-6000' there, isn't it? I'm wondering if the Bristlecone Pine area up in the White Mtns would get you up above that wind-driven particulate matter that you encountered down in the valley. I believe the Local Group has used the Westgard Pass area successfully.
Thanks for all the info on the Radians. I'll have to try one out soon.

Where to live around LA for dark skies?

Posted By Linton Rohr

Oh dear, that's a problem. Welcome to SoCal, nonetheless.
Mt. Pinos is generally thought of as the best site in the region, but the Santa Monica Mountains to the west of the city have some decent sites, despite being so close. The advantage being there is no light dome to the west and south, over the ocean. I had pretty good seeing last night, in fact. I look forward to getting out of here someday and living somewhere with dark skies all around - like Utah or West Texas for example. :-)
Feel free to follow up for more specifics - I'll even take you out observing sometime.

Lunar eclipse from Michigan

Posted By Linton Rohr



Hi Doug,
I shared that with you. I didn't notice the occulting until the star came out on the other side. A few minutes later, I saw another one emerge. I watched them slowly pull away from the moon - or vice versa, actually! It was a very spatial, almost 3D, effect.

Re: Your Thoughts:

Posted By Linton Rohr

Hello Harold,
Randy just mentioned the LX-90. I've got one and it's pretty easy to handle. Packs up in the trunk of my car pretty well, too. But you'd likely be disappointed if you're accustomed to a 12" aperture. I've got aperture fever and would love to trade places with you. I guess the grass is always greener on the other side... wink

Lx-90 vs. Nextar 8i

Posted By Linton Rohr

Hello Mike,
I can't speak for the Nexstar, but I'm very happy with my LX-90. It is my first scope and I've owned it almost a year. I was taking a peek at Jupiter around 5am and I let the drive continue to track when I went back to bed. Five hours later, it's still right on target. I actually see more detail now (in sunlight), than I could in the bright pre-dawn moonlight!
I imagine the Nexstar is pretty good, as well. Either way, you can't go wrong for those prices. That's got to be one of the best values around.

Meade for India

Posted By Linton Rohr

Hello Nitin,
I highly recommend you check out Anacortes first. You'll find them at: www.buytelescopes.com
They do ship international and are closer to India than most U.S. dealers. Tell them Astromart sent you.
