--------------------------------------
Segner's Wheel is another galaxy pair in interaction with dual nuclie. It is named by Vorontsov-Velyamiov after Johann Segner's 18th century's water turbine invention. It looks like a lawn sprinkler.

I have looked at this unusual object several times this dark period. It appears smallish in the eyepiece but the Two nuclei really jump out at you. The Nuclei of the North galaxy appears to be a little brighter. The South tidal tail is seen but the North tail is only seen near the core. I did a quick drawing at the eyepiece last night at 488X and it is a fair representation of what I could see. I really get a kick seeing the two cores like two eye's looking at you.

Be sure to see if you can catch the two nearby PGC galaxies as a bonus. One PGC 1906819 is MAG V 15.9 from the SDSS photometry and the other PGC 3830340 is MAG V 16.1 from the SDSS.

Check out this unusual pair and see if you can see the two nuclie and as always !!!!

Thanks Norman for catching my typo. I will correct it

[Norman]

this has been the only catchable thing these days due to moonlight ;-)
Nice Odw of course btw... already on my list since quite a while...

This is a very dynamic-looking object. "2 cores touching. N countertail curves CCW. S one stubby." 20", 360x, SQM 21.8.

I'm going to have to throw some glass at this--very cool-looking object!

Wow Jimi, what a challenge.

I had trouble to see both arms, especially the fainter northern arm. I first saw a peak within the arm. With lower mag and higher EP the arm was visible as a diffuse glow. Best view with "the eyes", my new ZAOII eyepiece which gave my 488x. The southern arm was shorter but brighter. All in fascinating object.

27", 293x-488x, NELM 6m5+, Seeing II-III
