Tarantula SHO and HSO

I cannot often see this from my yard so a NB first for me. I think the APP SHO potted formula is more restrained ,although the HSO has detail, NR only in PS

Just 50 min of each filter on the 1600cool over two nights on a refractor at f5.9.

The stars are a little eggy as the second nights guiding was bad. I think one of the weights slipped . Perhaps the bolt tip is worn.

They look great, the green just pops out. Have you combined the all as yet? A couple of eggs, but hey it's Easter.

Thanks Karl. Ha. Great Easter eggs in the sky. Bit scrambled maybe.

These are just Baader narrowband filters Ha, Oiii, Sii. The red one is HSO as there is a lot of Ha in the Tarantula. The other two are two are SHO formulas, where the strong Ha seems to make them more green .

Maybe I will do some RGB sometime but the NB is perfect for the Doublet refractor. No CA.
