Show date username difficulty separation pa_estim interest notes
Show 21/03/14 oldscope difficut separated 180 interesting The double is worth looking for. It's not too hard to find next to 47 Leo. It is the fainter of the two. The secondary is much fainter than the primary and only elongated at 214X. 286X splits it nicely and if it's steady enough it looks very good at 343X. My PA estimate is off a bit; given as 157 currently.
