hi guys,

I was lucky to observe the central star in M57, the ring-nebula, a couple times in my 20" f/3.7 dobsonian.
I would like to ask, who of you has ever seen this central star and what equipment was used for this purpose?

thanks in advance!

btw: here is an image of that nebula I took with my photografic equipment:

The smallest scope that I have seen the star with was my 14.5" Starmaster. It was a good night on MT Pinos. I have seen it in an 18" and 28" scope as well, both were Steve Kennedy's personal scopes.

Dietmar,

I had seen the central star a number of times in the excellent obsession 15 that I wish I still had from my 5.5 mag back yard, and it was a bit easier in my dark site that would be about 6.5.

On a decent night in that backyard, my wife could see it in our C11, but I could not. She had much more sensitive vision in the blue spectrum. This was noted on other stars, and dim objects.

Dietmar,
I have caught a glimpse via averted vision in my 14.5" Starmaster
a few times, but only on very good nights.
I have seen it better in some larger scopes at star parties, too.
But the 60" Hale scope on Mt. Wilson showed it bright and clear,
with no averted vision whatsoever required. Awesome! 8O

At Pinos one windy night most other scopes were shut down but Steve Kennedy had clutches on one of his 28" fast scopes....we saw the central star AND had fleeting glimpses of the second star also. The seeing was very good this particular time and night. And of course it was a Kennedy mirror doing the work! Three of us saw the second star so it wasn't only my eyes....Gerry

Beautiful image Dietmar. I can easily see it with my 25" Dob. I generally use a 5mm ep which gives me 635x.
