Fainter doubles

[Mr Spock]

Having seen β 137 in Lyra last night, it occurred to me there are so many doubles just beyond the likes of Cambridge and Haas. I only picked this one up because I was looking for something else in CdC and noticed ES 2026, Ho 89, β 137 and Ho 90 all in a row just above δ. The other three had secondaries too faint for the 102mm but within reach of the 250mm.

I've brought up Lyra in CdC and around the main square there's around 30+ doubles too faint for those catalogues but well within the reach of a 250mm. If I get a chance at Lyra again this year I'm going to put together a chart from CdC and see what I can get.

It all adds a bit of interest.

Oh great obviously I won't be able to see them being as I have a 5" but I would be interested in your views.

This is the map of Lyra I'm working on. So far I've marked on the printed version 60 doubles - and that's only half the map!

Bearing in mind the number of stars that are actually multiples (50% has been quoted) I think this is a really worthwhile project - mapping a small area like Lyra and listing the visible doubles for your scope/eye combination.

This map is only 2°. Given the size of the sky this something where you'll never run out of targets.

That’s a bit of an eye opener demonstrating just how many are out there
