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.
