I thought I would put all these together as one or two of them I have been working on for a while - it just so happens they have come together at the same time. Some were easier to do than others. Thanks everyone... Pier 4 - NGC 7333 Pier 4 is a ZWO ASI-2066MC Pro OSC, with a Sigma 105mm f/1.4 lens stopped to F/2, an Astromechanics focuser, guided with a ZWO ASI-120 Mini and ZWO Mini guide scope, on an Astro Physics AP900 GTo3 mount. The mount actually runs unguided, so the guide scope is in there only as a backup. For this object I used 90 subs each at 2 minutes long - totalling 3 hours.[size=100] [/size] Pier 7 - LDN 471 [size=100] Pier 7 is a William Optics FLT132 F5.6 APO, with a QSI 660-WSG Mono CCD camera, all on a Paramount MX mount. For this image I used a combination of narrowband data totalling an integration time of 560 minutes - 9 hours 20 minutes. [/size]   Pier 1 - NGC 6823 Pier 1 uses a 10 inch f/6.8 CDK astrograph from 656 Imaging and I used 12 Has, 18 OIIIs and 10 SIIs. I found this object more difficult to process than the others here, but each sub was at 10 minutes long, totalling an imaging time of 6 hours 40 minutes.
