Yeah - I did work with 10min subs for other objects later in the SPSP, but wanted to start off careful Brendan. I wouldn't have dared with the old guidescope, so your adaptor is definitely doing its work.
Much more than 10mins becomes a bit pointless with the newt though as the stars saturate with the QHY9s relatively low well depth.

Cheers Carl - I've had a lot of fun chasing the M objects down even when they are at silly altitudes off the horizon. Have learned a bit more about guiding too which gets a bit extreme that far over to the N

Thanks Luigi - I was pretty pleased all up considering the terrible signal to noise level for the RGB frames. Still, I feel I learned a bit about varying signal/noise levels you got from the different filters too - one thing to read about it, another to get some practical experience under your belt. Plenty to learn and explore in this new LRGB domain...

perpetual cloud here. Not even a chance to get 2 subs.

Thanks Clive - at least I can say I've checked it out - pretty decent size object compared to our Southern galaxies

Thanks for looking Mario

Yes - there's another nearby object I ended up cropping Frank - haven't looked up what it was, but the two of them in a single frame with decent exposures would be nice. Perhaps one day will get a chance a lot further north.

Thanks Dave - I think its a bit late in the year now. I didn't want to spend too much time on it as it was pretty low, but then again you often wish afterwards you had more time. One problem with having the CCD is you tend to want to go deeper, making it harder to explore more objects.
There's very little sharpening and noise reduction on this - the thing that brought out the centre detail was a couple of passes of the HDR (high dynamic range) wavelets in Pixinsight. The function is specifically designed to bring out distinguishing details across a wide brightness range - a little bit like using the Highlights slider in the Shadows/Highlights tool, but lots more sophisticated (probably a gross generalisation the PI guys might not agree with....
). I haven't played with it a lot, but have seen people mention its good on galaxies so gave it a spin and happy with results.

. Astroplanner freeware is awesome for figuring out when these low objects will be visible (times and months of year).
Thanks everyone for looking....
) visible from this latitude. Still, this did give me confidence to track longer subs for longer periods on latter objects at that star party with the QHY9 setup, and pleasing to get a bit of detail in the nucleus of the galaxy even if the colour is $#@! Cropped fairly heavily to compensate for poor flats and a stray object passing through a couple of frames.
..so that's a top shot Rob 
), still, M106 doesn't even quite make 10deg from Wiruna at culmination so as I said, a top result
