Hi Rodney, yes those stars at the core are difficult to manage so you can resolve them but not to much that you reduce the light from these very bright O stars.

would it have been better with a focal reducer? ie -
more FOV and more intense light.

Hi Allan, Yes this was taken at full FL. Given this scope is 20 years old and about 4 hand to me, that the company that made these excellent scopes is no longer in business, finding a focal reducer for it might well be next to impossible. For a bigger field of view I could use a much larger sensor though. Sometimes one has to be happy with what is available. I take your point though, in a perfect world a reducer would great to have.

A bit sharper than Dave’s M20 last month , although his was captured from the Burbs B7 skies with a 14” scope
Thanks for posting

Hi Martin, given that the object is very bright, the relative darkness has less effect but rather the seeing becomes critical with such a long focal length. I did have a run of pretty reasonable seeing for this image. We have been having one of the driest starts to the winter season in 20 years, which has led to long spells of quality seeing. The impact of which has led to allowing the resolving power of the scope to shine through. Although I wouldn't mind it being at around 4000 metres to really see what it is capable of achieving.
