SH2-129 Flying Bat & Ou4 Squid


Recommended Posts

HOO image comprising 59x600s Ha & 76x600s OIII, total integration time of 22.5 hrs.

This is the longest I've ever spent on a target and the Squid is extremely faint. You read about it but until you try and image it you cannot really fathom what an elusive target it is.

Processing it was very hard work, but I'm very pleased I got it. With a better quality OIII filter at 3nm instead of my 7nm I could have got more detail but all things being equal I cant complain.

The good thing is the data itself was very clean with a great SNR as you'd expect from the integration time.

AS294MM via WO Star 71 II.
