Evrening everyone!
Since having posted the widefield of the Veil nebula the other day, I have been trying to process various data over the last little while, fitting it in between things before other things press in! As that is so, I have processed three objects, as detailed below. Thank you everyone for your support and encouragement.
Have a good night.

Pier 3 - NGC 6888 - the crescent nebula
Pier 3 uses an ASA 12n F/3.6 Corrected Newtonian scope, a Paramount ME and a FLI PL-16803 Mono CCD - 1x1 Binned. I processed 6 Ha subs and 20 OIII subs, each at 10 minutes long - an integration time of 4 hours 20 minutes. I did have some difficulties with the vignetting, so I cropped most of it out. Also, I am not very good with the blend of narrowband colours at times, and so I produced two versions of this, one of them having used background neutralisation - the redder of the two images - although that throws out the individual RGB histogram alignments. I am not sure which one is best, but here they are anyway. They are both processed as HOOs.
Pier 5 - M16 - eagle nebula
Pier 5 uses a Takahashi Epsilon 180 F/2,8 astrograph, on a Skywatcher EQ 8 mount with a ZWO ASI071 Pro Colour CMOS camera, and I used 240 subs at 1 minute long each, which is an integration time of 4 hours.
Pier 1 - NGC 6960 - the western Veil nebula
Using a pier I have never used before, I managed to process the data for this famous object. The pier uses an AD250 10" F/6.8 Dall Kirkham scope, a 10 Microm GM1000 and a FLI ML-8300 Mono CCD 2x2 Binned camera. The image is a little noisy, but that maybe due to only having a few subs, or more likely my processing! The image comprises of 12 in Ha, and 12 OIIIs, each at 5 minutes long exposure time. The integration time is thus 2 hours.
All the best.

Hello Simon,
You have been busy with all the new images you've recently posted. Unusually for me not had much spare time recently, and finding so much good stuff here on the forum. Given the pace I work at, even when I do have the time, there is probably 3 weeks work represented in these images just here.
You did a great job with the Veil with just 2 hours of data. I'm not surprised it's got a bit more noise compared to most of the other data due to that factor, so I imagine it would be difficult to extract any more detail. Nice to see the Eagle nebula in its entirety for a change, immersed in a sea of nebulosity. Definitely worth a repeat if that filter Steve mentioned can be fitted later on. That pier will become so popular that there might be a long queue to use it.
Hope you are doing well,
Ray

Yes it would be interesting to see how the image would be with that new filter which you have talked about; such variances can change things a lot. I am pleased you liked the veil nebula, although for a change it wasreasonably straightforward to produce! : ) There was a bit of an alignment issue with the various subs so there was quite a bit of cropping, but it would have been better like you said, if I had had some more of them, but these are early days. I am generally better than I was thank you for asking, and I am looking forward to seeing some more of your images in due course. Cheers for caring Ray, and may free time come your way! Si
