Nice story about a very exciting little piece of sky. There's a lot to enjoy by just scanning through the region.

For the absolute beginner I find that M57 is better located by first finding the 5th magnitude star just over 12' WNW from gamma in the direction of beta; M57 is then almost exactly in the middle between this star and beta.

I love hanging out in Lyra.

Thanks for [some of] the truth about Lyre, Lyre.

Just a plug for two carbon stars: T Lyr and HK Lyr. T Lyr is better known. HK Lyr is about 45' SSW of Zeta Lyr.

Also thanks for mentioning the "7" asterism near M56. I hadn't thought of that before. Why? There are two more stars. They are located on both parts of the "7" and create overall a triangle within a triangle. For several years, I imagine this five star "asterism" to be a slipper to which M56 is a puffy little pom pom or tassle.

Can we get some more info on ISK 1?
Plotted but not explained; listed but scant info.

I use all 4 editions of Starware for reference.

Not much info is available. From "Star Clusters" by Archinal and Hynes, Iskudarian 1 "was postulated by Iskudarian and Saakian [1961] as a possible cluster of white dwarfs in Lyra. They suggest it contains 26 stars with V(?) magnitudes of 15.8 to 20.2 spread over an area of 2 deg by 1 deg...On the surface, the physical existence of a cluster of white dwarf stars seems unlikely, but it is not clear is sufficient research was done on these stars to demonstrate its existence."

This CN thread from 4 years ago might offer a little additional insight. I included it in Touring the Universe through Binoculars back in 1990 owing to its size and little publicity at the time, but it would seem that Isk 1 is really not within the realm of the binocularist.

I'd like to pass along this observation sent to me the other day by CN reader Mike Allen from OH, recounting his experience viewing M57 through binoculars. Thanks, Mike!

I enjoyed your recent article on the Cloudy Nights web site. I have seen the M57, under a dark sky, in my 8x40 Zeiss binoculars as a star-like dot. Using my 16x70 Fujis it becomes a tiny round fuzzy object, but no central hole was observed. I've not been too involved with variable stars, however I do intend to monitor those you mentioned in your article.

Anyone else??
