21/2/19 Swadlincote C6r on Neq6 mount.
A short session before the Moon glow got going. This time it was the “snow Moon”, big bright and silvery as SWMBO pointed out .
Very surprised to get a lovely unfiltered view of NGC 2440, a bright +9.3 planetary Nebula in Puppis. Discovered by Herschel , it bears the hottest central white dwarf. Continuing with obscure a lucky view pulled out by averted vision of 15 Hydrae . The B companion giving a 1.2″ split with two further faint companions. Staying in Hydra and a great view of M48.
Two further challenges in Gemini , Σ1037 and Σ1081. Looking at the Trapezium , the E star was quite obvious , but no sign of the F . Probably as Orion rested on the town lights. We’ve got led streetlights, the glow is pretty fierce , but doesn’t give that horrible orange glow. Just a few clusters worth observing ,M46, M47 , M50 and the compact NGC 2420.
From here a six inch aperture (f8)gives equivalent views to my 8″ Newtonian (f6) , but with increased contrast and more defined diffraction discs on bright stars and planetary views. The seeing and transparency of the atmosphere dominate , but it is possible to get down to below one arc second separation. It’s quite surprising to get so much detail from simple equipment . The Eq6 holds the 11.5kg ota weight of the six inch refractor, with a carrying capacity of 25kgs , there’s room for more !
Lovely early session under ,
Clear skies ! Nick.
