Using TV powermates on Ethos 21mm

Posted By Linton Rohr
Hi Tim.
The Powermates perform very well, but they are long and heavy, and might give you balance problems. If you're changing back and forth a lot and having to readjust your balance (refractor?), that could be quite a distraction. Convenience should be a consideration. I have a definite bias though, for using individual eyepieces, without barlows. I'm in good company...Al Nagler expressed the same sentiment in his presentation at PATS yesterday.
If I was trying to assemble a small set of premium eyepieces right now, I'd check out the Naglers right here in the classifieds. Prices are down lately, and you could put together a good set of Naglers for the price of a new 21mm Ethos. A 22mm T4, 12mm T4, and 7mm T6, for example. Or maybe you can sneak in a used 8mm Ethos at the high end. (I think that's where the Ethos has the biggest advantage.)
There's my 2 cents. Spend them well. wink
Have fun, whatever you do.

Fogbow

Posted By Linton Rohr
Nice shot, John.
I saw a vivid moonbow back in 2002 on the big island of Hawaii.
There wasn't really fog involved...just moisture in the air.
We were on the saddle of the island, driving down from the Mauna Kea visitor center.
We had just completed their astronomy program and it was midnight or later.
I was still shooting slide film back then, so I'd need to fire up the slide scanner.
There's about a million other slides needing to be scanned.
I ought to get to work.

I don't know what I was thinking.
My wife can sell this sweatheart when I'm dead and gone.

Took it to the recent PATS show, where Uncle Al took great interest in it.
Yes, of course he signed it for me. wink

Ganymede Transit, 10/8/09

Posted By Linton Rohr
Hi Jon.
I happened to catch that transit just after setting up my 14.5" for the super fabulous LCROSS impact event. wink
So I not only saw dozens of tiny craters in Clavius, but a Ganymede transit as well.
Seems like there was something else...hmm, let's see...

Debating among EPs, need advice

Posted By Linton Rohr
Zhuo,
If you like the 13mm Ethos and you can afford the 8mm, that seems like the obvious choice to me.
I have spent a lot of nights using little more than my 26mm T5, 13mm, and 8mm Ethos.
It is amazing on GC's, and many galaxies, M51 for example. It's also excellent for planetary use.
Better eye relief than the T6 Naglers, plus a big eye lens, and better contrast.
I use mine in 14.5" and 10" dobs mostly, similar to you.
Have fun, whatever you get. smile

I believe this is East Temple, just north of the tunnel exit.
