Description

I managed the other day to get some OIII data, although not enough by far, to complete my HOO of this iconic object. I obtained 88 Has and 56 OIIIs, each at 3 minutes in length. This is an imaging time of 7 hours and 12 minutes. It takes a bit of getting used to, this classic Cassegrain, but running at f9 makes it a bit easier to handle. I have also included a starless version of this, which I find to be a pleasant thing. Thanks everyone...
