Thanks everyone, I appreciate your feedback and I'm very keen for some more clear weather this weekend :-)
Mark - I took a (very poor) wider field image of M20 late May 22 and it is *full* of stars to the point of distraction - the star fields are a sight to behold. Re using a 294MC for stars, it seems like a common thing to do. I have that camera and was thinking about doing the same but that would depend on how much time I have.
Dave - PI is awesome but will break your brain
I'm spending a lot of time in PI but still use APP a lot. I find for some targets, eg. galaxies, AAP produces better colours with little more than a few tweaks of saturation. Btw, a higher res version of my M20 is
here. Apologies in advance for the comet-like stars on the LHS, my SCT's collimation needs a solid tweak ... if I actually care enough (per John's comment
)
John-dude - mate, thanks for the hot-tip about L integration time; I did't know that and will def follow that rule-of-thumb. When do you roll the L ch into your workflow? After you've finished the RGB or SHO processing?
Time to process the M20 SHO data. Alex
