IC434 and Barnard 33 (horsehead) Ha_O3_O3

IC434 / horsehead nebula, captured using LB-0001 (lightbuckets.com 24" R-C telescope)

 

i think this is kind of weak sauce here. i've seen many other people with (Ha:OIII:OIII) combos for this object, so i thought i'd try it. however, i found that i got reasonable Ha subs with relatively short exposures (420s) but the OIII subs here are 4x1100s and still there's pretty much nothing there. as a result a lot of the stars are red since there's no data in the G,B channels for them.

 

i probably should have just done Ha(Ha+R:G:B)... but at this point i've spent a lot of $$ and maybe it's good money after bad? or maybe i should just start over. or do more research before i schedule time :)
