Hello, a quick sweep across the autumn sky tonight from west to east with a 90mm refractor stopped down to 60mm (f15) giving beautiful double star images. Gamma Delphini at x40 showed up as a yellow primary with a slightly green tinged companion. Next, 61 Cygni, the first stellar distance, announced by Bessel. A cute pair of white stars easily split at x23 and well seen at x40. At mags 5.2 and 6.0, they actually look closer in brightness to my eye. Gamma Andromedae is a colourful pair and at x80 they stand out brightly: a pale yellow primary and a blue comes. The dew was settling by 21.00UT and time to take the telescope in to de-fog.
Kind thoughts, Bob

Hello Bob,

I like these stars, too. Especially Gamma Delphini.

Other good ones at the moment are Alberio (Cygnus), Struve 525 (Lyra), Epsilon Cassiopeiae and Epsilon Lyra (double double).

Happy observing,

Nigel

)&)(*)(&()&() show off

I have trouble remembering the Constellations let alone star names, terrible when it comes to setting scopes up :(

Get yourself a Sky Atlas. I use Sky & Telescope's Pocket Sky Atlas.

Beta Cygni is called Albireo and not Alberio! Sorry to be a real pendantic clever-clogs!!!
(And a question somewhat related to this...Is it possible for Greek alphabet letters to be incorporated in a tablet or other computer?) Regards maf.

Ooops! Got my `e' and `i' swapped round!

Regarding your question, Greek letters are included on computers in writing packages such as Microsoft Word. I no longer use Word, so I can only speak in terms of Open Office Writer where Greek letters are included in `special characters' under the `Insert' menu. Word will have something similar.

The question is whether they would transfer to the text on this forum; let's try! I'll past in a `beta' from my Open Office package: β

I don't have a tablet, so I can't comment for them.
