Cheers Peter. I did contemplate the image composition along with crop. I liked the bright star cloud wandering through to the frame so a tighter crop may not have conveyed this. There are a few other interesting features further left of the frame too.

Not sure about the comments. Posting at night you often see a large number of guests online. Perhaps lurkers with no account or my images are too intimidating for some to comment.

It would make an interesting thread about what level of colour the stars should really be as the digital age has made it all too easy to manipulate colour.

Looking forward to your 16070 images. I imagine you will get much more depth and luminosity in your images from that sensor which I think is the next best thing after the 16803 and with the slightly smaller pixels better suited to your 16/F3.44 rig.

Greg.
Thanks Greg. Yes, we could debate star colours for sometime. The fast the f-ratio the harder it becomes as you're aware. For reference, all my RGB subs are 240s each with the KAI-16000 chip. I found 300s too high. The KAI-16070 will no doubt be different. I have a couple of subs of M83 taken unfiltered i.e. not through a lum filter and even moderately sized stars hit 65k in 240s subs with the KAI-16070. Filtered will not be an issue I suspect. I'm still doing 900s to 1200s subs at F/3.5 for narrowband subs to suck in the super faint stuff. I don't get saturated stars with narrowband data even at that sub exposure length. Still some more tuning to do with the optical train changes for the Aspen camera but will release something soon, perhaps of a mainstream object for a change to make it easier to compare with other images. Thanks again for the input.

Very nice combo of objects. Looking forward to your data with the new gear.

Thanks Tim! Pleased you liked it. If you are looking to do any collaborative imaging again, like we did with IC1283-4, just let me know. I'm always up for long focal length mosaic processing challenges! Once I get this set up bug free, I'll embark on some mosaic work.
