NGC4535
« on: 15:58:04, 17 April, 2018 »
This is a beautiful barred spiral galaxy in the Virgo cluster.   Quite bright at mag. 9.8, but with very faint outlying areas, not so easy.  Coincidentally featured in April Astronomy Now Sky Tour section, but they used an ESO image!  I say coincidentally because I started this project on 8th March with some mono data.  Then more mono on 20th March, a smidgen of colour on 24th March, the rest of it on 14th April.  Shows what a dreadful Spring season it's been that it has taken me over five weeks for one image!!

Anyway, here is the result.  Luminance 27 x 10 minutes, RGB each 7 x 10 minutes, all binned 2x2.   QSI683wsg and SX AO unit on 10" RC Truss.  Even with all that Luminance data, still a bit lacking in detail, but hardly surprising - the seeing has been dreadful for weeks now with the Jet Stream practically overhead.  Some patchy colour noise as well - IF I get another chance I might try for more colour.  But my dark skies are rapidly disappearing for this season.

Cheers,

Peter.
