Thanks for this! Somehow neither of these pairs was on my list!

The two brighter pairs are on my list for tonight (or tomorrow night, depending on when I can get out). Something to look forward to.

The BUP pair has my interest as a test of some new eyepieces in the 15" before Mr Moon takes over again.
You also managed to capture mag 14.4 galaxy UGC6468 in the lower left above "Tau Leo". Very nice!

Observed this "double-double" tonight. (8" Newtonian f/5; 17mm & 8 mm Stratus eyepieces.) Both were easy to split. Tau Leonis had a nice color contrast, pale gold and bluish-grey. The double next door, 83 Leonis, was tighter, and with slightly high magnification than I needed to separate the components (didn't take much to begin with) the colors were more apparent, with both of them looking a sort of golden-orange. (I was never sure I saw BUP 9002, let alone split it.)
This is the first time I've observed these pairs. Beautiful view. They're on my list for repeat visits, now.

Intrigued by this post I finally had a chance to look at this "double double" last night with my M6 and C8. The clouds kept rolling through but around 23:30 the western sky finally cleared up for a spell. Very pretty and easily split at low powers in both scopes. A long focal length EP with extra FOV helps frame both pairs with some additional sky/stars - as seen in the photo above.
Thanks for bringing these to our attention.

I have joined the Leo double -double club too.
Last Thursday night (4th May), I was surprised to see all 4 stars separated at a mere 11X in my 70 mm apo.
In my main 158 mm apo, I could make out the both primary stars had nice yellow -white tints at 40X.
There are plenty of field stars surrounding them also.
My deepest thanks to Steve for his very fine image above.
By the way, Sissy Haas's book of double star book highlights the double double.
