Inspired by recent Paul's excellent interpretation of this nebula, I thought of having a go at it as well. Unfortunately, weather has not been too great so I am still to collect O3 data. So far I have 5.5 hours of Ha and was very keen to utilise some new PI skills I have learnt today from Rick, who very kindly attempted to teach us mortals the magic of PI.
Image scale is 1.33 arcsec/pixel, collected with my trusty 4 inch doublet.
Looks good Slawomir. I really like that dark dusty nebula out to the right hand side too. I did not get that into my field of view. Great detail so far. Looking forward to the finished image.
That's really impressive with just a 4" scope Slawomir. Lots of really delicate detail in 6164. More data would help to knock down the (unobtrusive) noise.

Your wide field shot explains why the outer shock ring is much stronger toward the bottom of the image, and very weak toward the top right - there's no pre-existing material there for it to slam into.
I am continually surprised at the quality of your images Slawomir. A 4 inch doublet is used here? Wow. It looks like the result of a much larger scope. That 3nm Ha filter and the magic of these Sony CCDs plus such a good match of the 690 sensor is working big time in your favour here.
Wonderful image.
Greg.

I have recently advanced from a balcony-astronomer to a backyard-astronomer, and being equipped with new processing weapons thanks to Rick's generosity, I am hoping that the quality of my images will improve. This is my first non-balcony shot and I am already enjoying being able to shoot objects when they are higher up in the sky. But I have already encountered a new to me enemy - dew...somehow I never had it when shooting from a balcony, perhaps due to a higher elevation above the ground?
I agree that after some upgrading and tweaking, my 4" doublet combined with Astrodon's filters and QSI690 is a neat combo that I am yet to learn to take a full advantage of. Perhaps a better quality mount would be my next upgrade. The current one obviously does a decent job, however, it is at this moment the weakest part of the system.
May the Force of gravity be always with you and keep you grounded.
that is excellent Slawomir, so much detail from a small refractor.
after spending a bit of time on this with a big 12" f4 newt and dslr and seeing your image, it has really highlighted the imperative that I get off my behind and move to cooled mono.
Nice one mate. Are you planning on getting some OIII/SII on this?
I know how you feel about the dew, my place is pretty bad for it. The other night my dew heaters failed and I got an entire one 7min sub before it dewed up so badly as to become unusable. It's rare I get a dry night and most often when I do it's because it's too windy to image.
Thank you all for you very kind comments and encouragement.
I have now also collected just over 11 hours of O3 data. Will try to add a few hours to Ha data before making an attempt to stitch it all together. Weather and time permitting, would also like to eventually collect S2 data as well.
Once again, thank you all very much for taking time to check my efforts and for commenting on my journey
... waiting for the addition of the O3
