    Best of fall to winter Shakhbazian groups

    I have a 22 inch f/4.2 and am headed to CalStar in a few weeks. NELM is probably 6.3 or so. (not really sure but certainly not MUCH worse).

    Can you point me to a list of 'doable' Shakhbazian groups? I have Alvin's book. Thank you Alvin!

    Just something to 'stretch my observing legs' with. (I love it). When I say doable, of course I mean with effort.

    Ideas?
    (If this is already covered, please just point me to the thread or page. I do not wish to waste peoples time!)

    Hi Jeff,

    Searching "Shakhbazian" in this forum turns up various ORs for individual groups, including a couple Shakhbazian OOTWs.

    Steve once pointed me to Italian observer Andreas Domenico's website where he has observation reports for 22 groups, with varying degrees of success, using an 18-inch scope. It's an excellent resource and inspiration.

    See you at CalStar!

    Thank you. I knew of Andreas' site. What I have found beyond that is observations with 25 to 48 inch scopes. Hence my wording of doable in a 22. But I guess nothing ventured...

    I will spend more time searching here. Thanks again for the reply!

    Jeff, please read the descriptions of the observations by Andreas carefully. He did his observations with an 18" telescope.

    The 5 best Shakhbazians, in my opinion, are Shkh 16, 30, 166, 202, 317 (= HCG 97). Shkh 202, though, is a Spring target.

    I'd also suggest Shkh 40, with brightest member IC 1695. This is actually an Abell cluster (193) with several challenging galaxies at V = 15-16.

    If you need more info on any of these, Jeff, let me know.

    I was browsing through Alvin Huey's Shakhbazian observing guide tonight and noticed that according to that guide Shkh 30 = HCG 97 and Shkh 317 is a chain of relatively bright galaxies. I also noticed that Vizier has multiple Shakhbazian catalogs. Is it possible that Alvin is referring to a different catalog than Steve?

    EDIT: According to NED indeed HCG 97 = Shkh 30. The plot thickens ;-)

    Thanks for correcting the mistake. By cutting and pasting "= HCG 97" was accidentally pasted at the end of the list, instead of attached to HCG 97. Also, technically HCG 97 is a quintet (5 galaxies reported by Hickson), but Shahbazian 30 includes several additional extremely faint galaxies.

    I think the catalogues are similar VII/89B is the original Shakhbazian catalogue whereas VII/196 are catalogues of the individual galaxies in each group. The ReadMe files will tell you what they are. I think this may have been my fault many years ago when I asked for them to be added and they added both.

    Hi All,

    You can have a look at observations, drawings, and notes of 25 Shakhbazian groups with a 25" scope at:
