What are the top 10 brightest tidal tails visible?


Hello fellow observers. The last 10 years I've been using a 18" Obsession f4.5 from desert skies, SQM 21.4 to 21.65. I've seen the tidal tail on NGC 4676 many times. Its a good indicator of sky conditions, and I believe is one of the brightest. I've also seen the tidal tail on NGC 4039, the Antennae once. I was wondering if there is a list in order of brightness. I'll be taking a trip to a Bortle 2 zone high on a mountain in August. I would love to add some more tidal tails to my short list.

Here are a few more with visible tails from my recent observations with 16-20": Arp 101, 188, 241, 295.

NGC 6621 is another easier one (visible with 16").

Good one. I too saw it in 16", although my notes call it an arm. It is definitely a tidal tail.

Don't know if it belongs to the brightest, but surely ons of the prettiest: Arp 273

Thanks everyone for the info. I guess there is only a handful of objects, I thought there were a lot more. I guess I'll concentrate on the flat galaxy catalog I've been working on for awhile. I hope the skies will be clear on this trip, its been a bad year for observing so far.
