Short vs long nb subs
Hi all,
While I have been working on overcoming limitations of my mount, I decided to test whether short (within reason) narrowband subs will yield a similar result to longer ones, given the same total integration time.
The attached shows a section of a stack of 22 five-minute subs (left) and 9 fifteen-minute subs. Total integration time is a tad less for the shorter subs, but anyway the difference between the two is not as astonishing as I was expecting.
Data captured with 3nm H-alpha and ICX 814 in Paddy in Brisbane.
Hopefully I will be able to produce at least a semi-decent image in the coming weeks - it has been ages since my last one...
