Hi Doug,
Sounds like it was a howl !
Good to see you got your teeth into Struve 1604 -- it is one of the better triples of its type in the sky -- where the stars form a nice triangle with _approximately_ equal sides as opposed to the more boring "line" arrangements or the "Acrux" type with a tight pair and a distant tertiary.
Here is my observation of it on 10031998 (just over 10 years ago) with my old 25cm. I rated the seeing at 7/10 but the transparency 3/10 with a fat gibbous moon high in the north:
x181 17' TF. The telescope is forming lovely small fairly stable Airy discs. Absolutely beautiful ***. The components almost form a RA Tri, just --acute from this. A is mag 7. B & C are both mag 8.5, 8" and 12" separated in PA 80 and 40. C is only perhaps 1/10th mag dimmer than B. Very, very pretty.
Nice report. Good to see the Argo working well!
Best,
