Obviously, as can be seen from your image and also in images of many other tidal tails, dwarf-galaxy-sized objects that are very rich in (very luminous) O and B stars, definitely do form within tidal tails, as there is (often, but not always) plenty of gas in the tails.


Whatever the case, the knots in tidal tails are interesting and extremely challenging objects for astro-imagers.

cheers,
Robert

thanks very much for the info Robert - have not yet read the refs, but will.

... actually, a design that has been around for over 300 years probably has something going for it and modern CCs have fixed the single major shortcoming. Running at around f4 sure keeps imaging time manageable.

Ah yes, Newtonian power!

Thanks for the feedback Rolf

Thanks Erik. thankfully, seeing was pretty good for part of the period.
