    M1?

    It is tricky to find - immediately above bright zeta Tau [lower Bull's horn] are two faint stars forming a triangle with zeta - follow a line through these two faint stars westward for 2/3rd their separation and slightly downwards for M1 - good luck If you have an equatorial mount then center M42 Orion Neb using low power EP then release Dec lock and sweep scope vertically upwards - M1 and M42 have virtually the same RA My M1 pic via little ETX-70 e-finder from last week below:rolleyes:
  2. Here's recent M82 Cigar galaxy and M1 Crab in 60s exps - data on image:rolleyes:
  3. Hi - my first post here:hello2: I'm deep in London LP but do DSOs in brief exposures via my 12" SCT at f/3.7 + SX Lodestar-C in typical exp 1m -5m [in 1m subs] to make the most of few clear nights and to get as many different targets Anyone do this sort of imaging - for me a substitute for eyeballing:rolleyes:
  4. Hi - some more books [that may not have been mentioned:rolleyes:] Optical astronomical spectroscopy by Prof Chris Kitchin [ioP] Astronomical spectroscopy by A.D.Thackeray [Eyre & Spottiswoode 1961!] Practical amateur spectroscopy by S.F.Tonkin [springer] PS; my 1st post on SGL:hello2:
