Another unusual NB mix of spider
I was blown away by that Spider Andy01 posted a few weeks back and by the audacity of his O3,N2, S2 mix. So what better target to try out my new (second-hand) STF-8300 recently purchased on IIS (thanks David).
The seeing has been lousy and so this is not as sharp as I'd like but - that's life.
I don't have an N2 filter so this mix is mapped Red(O3), Green (Ha), Blue (S2).
The scope is a Tak FSQ85ED and the exposures are quite short - 6x5minutes each filter. Of course more data would be great but these days, even rolling back the roof is more often than not a waste of time. High levels of dust and haze in the air.
Anyway, hope this doesn't send too many NB purists into early PTSD.
Peter
