Kemble's Cascade 70-300mm Tamron lens
« on: 20:25:21, 27 December, 2017 »
Very cold here this evening. And with a bright Moon.
I am on holiday. So I don't have to worry about getting up tomorrow  :big_clap:


I have just finished imaging Kemble's Cascade. I used my modded Canon 1000D and Tamron 70-300mm lens, at 300mm.
1hr 15 min in 180 second subs with no guiding.


Stacked in DSS and I used StarTools to round the stars. The lens suffers badly from coma, when shooting starlight.
