More RASA experiments - M27 - What can be done

[Catanonia]

With the RASA8, I gain speed for the loss of focal length. Does this mean small planetary nebula are out of reach for me.

Only one way to find out and that is to have a play and see what happens.

So again under Bortle 6 skies, light intermittent hazing high clouds and a full moon, I grabbed 10x 5 min 1xbin subs with the RASA8 and ZWO2600 MC Pro

I am actually surprised how good it came out in less than idea conditions. More subs, darker and moonless / cloud less skies would certainly help, but it can do it.

I could even use the dither data and drizzle to 2x size if I wanted to, but kept it at a 1 to 1 crop for this image.

Just about make out the faint blue double shock ring.
