The nebula is vivid, lovely huge, elongated 1. 5X1 with a excessive floor brightness center and fainter glow round it. This nebula has a faint eco-friendly colour. including the UHC or the OIII filter indicates the outer nebula with a lot higher distinction. The filter really makes the Dumbbell Nebula virtually around via filling within the crucial sections. a long time in the past on the Riverside (California) Telescope Makers’ convention, the folk from Questar drove around the US and arrange a Questar 12, a superbly made 12 inch f/15 Maksutov. Like many an enormous Maksutov, it took fairly your time to chill down. a hundred and twenty Northern summer time Nebulae notwithstanding, via middle of the night the perspectives have been very good. At 180X with a fifteen mm eyepiece the Dumbbell Nebula was once a gorgeous gentle eco-friendly colour that truly confident you that the item you have been seeing was once a gleaming gasoline cloud. there have been 12 stars concerned in the nebula and confirmed the nebulosity to have a mottled texture, slightly just like the Orion Nebula round the Trapezium. those mild and darkish markings have been visible around the face of the full nebula.
