A very cold night. Keen to use my new UHC narrowband filter – It gave amazing images of the Orion Nebula M42- I had read in books how the nebulous glow extended so far but tonight I really saw that for the first time – spectacular!
I then went on a tour of Messier objects: M42 right up to M51, the Whirlpool galaxy – mostly they were open clusters. M52 in Cassiopeia was located somewhere behind my roof to the north so couldnt see it!
Then tried 2 of the Virgo cluster of galaxies: M85 and M100 – I think the UHC was helpful in picking them out in terms of background contrast but didn’t add to detail seen.
In terms of galaxies, I really must think about how to get better images (*) but filters are certainly very useful for nebulae.
* ? bigger aperture and faster f stop rather than higher power eyepieces – that would be a big Dobsonian then
