It is a guided shot for 15 mins at 800 ISO through an Orion ED80 and Canon 350D with an F6.3 focal reducer and Orion Skyglow filter.
Whole assembly was piggybacked on aMeade 10 inch Lx200 classic scope and the autoguiding was carried out via an Sbig St4 autoguider.
The central star is at 13.84 mag and the Helix is one of the closest of all planetary nebulae: Lying at a distance of perhaps 450 light years.
It is also one of the apparently largest planetaries known.
Its apparent size covers an area of 16 arc minutes diameter, more than half of that of the full moon; its halo extends even further to 28 arc minutes or almost the moon's apparent diameter !
This Image of the Rosette Nebula was
taken at Jerrara Dam and is a stack of some 6 images in Maxim Dl.
