90 Hercules

[Perseus_m45]

Last night the sky was very nice up until around midnight. I was able to view a few doubles but 90 Hercules was a stand out for me on this night. I was able to split this star using an orion epic 3.7mm eyepiece.  I have a clean split on this star with the primary being a ruddish orange yellow and the secondary a beautiful blue very intense,,,a very nice double but difficult to split in the 6 inch f/8 . This would be a good test for your 6 inch or even a 5 inch. And I would guess maybe even a good 4 inch scope might split it.

Oo - the gauntlet is down... now for a clear night with steady seeing. (Don't hold your breath.)

I had a try tonight as it is clear, although ggod/bad/patchy seeing. Fairly easily split with my 5" Mak at x200, the space between the two about one Airy disks worth. I couldn't see a lot of colour contrast - probably more aperture needed for that!

I had another look tonight - excellent seeing! At x380 (still sharp despite the laws of physics!), the yellow colour of the primary and the blueish colour of the secondary are a lot more obvious than at lower mag. A nice double!

A lovely 1.5" split with magnitudes of 5.3 and 8.8.Nick.

Soooo nice that geeks like us can maintain contact from all over the world and look at the same things.And chris I have that same mak the 127mm. It is a lovely little beastie , but your right , it does not show the same color as my refractor..

Nice report. I should really get out and start looking at doubles.

Lately every night when I get out I have to make sure to take a peek at Alberio. I will have to make sure to start finding some others.
