Greenwich Astronomy Photographer of the year (Daily Mail warning!)


Recommended Posts

A 10" Dobsonian (mount) is an eye-opener when viewed for the first time, but the experience is fleeting. Rotation of the earth makes it hard to keep an object in view, even at 20x. I'm leaving tongue prints on a, 8" or 10" Schmidt-Casagrain with a German mount, stiff enough to hold a camera over the eyepiece.

Yes they aren’t for photography at all.

I like the simplicity of design, no batteries required.

 

You are right about the tracking issue but I bought one of these to offset that.

A 100 degree field of view.

Tele Vue Ethos 21mm Eyepiece (2.0") ETH-21.0 B&H Photo

Diamonds on velvet.

Here is a review that describes it well:

“The Ethos 21 mm is a Christmas gift. However, it arrived in August. I told my wife that I should probably check it out before Christmas (in case it was damaged - ha ha). I opened the box and stared in awe at how beautiful it was. Lucky for me, it was going to be a clear night. When night time descended upon us, we both wanted to check out the Ethos 21 mm. I also own a 31 mm Nagler T5. The Ethos 21 mm is parfocal with the 31. I pointed the telescope at M13 (the Great Globular Cluster in Hercules) with the 31 in place. This alone blows you away. I then swapped in the Ethos 21 mm. I could not believe it. Stunning. I was speechless. First the magnifcation went from 95 to 140 (I have an F/8 14.5 inch RC). And even though the true field went from .82 to .70, the apparent field increasing from 82 to 100 was phenomenal. When TeleVue advertises that you will space walk with this eyepiece, they are not kidding. The star field was expansive. You literally had to move your head around to take in the entire field. I felt like I fell into my telescope and was floating in space. M13 never looked so brilliant. The stars were pin points to the edge of the field. It is simply unbelievable. I had to continue to check the eyepiece out seeing that once the test was over, I wouldn't see it until Christmas. I can not wait until Christmas this year. Sure, the Ethos 21 mm is expensive. But it is worth the price. Highly recommended.”

 

The Tele Vue will make your heart beat fast on a cold clear night.

Ed, you're in the Chicago area, right? If so, where do you go to view the dark skies? I have a view of the east overlooking Lake Michigan but usually can only see a few stars. I'm at the north end of Chicago. I have seen Saturn's ring with my Meade 130mm Dobsonian but wish I could see more.
