The power of Flourite, NGC4945 and little known HII regions in Cantarus
Hi all
Once again I used The fantastic 300mm f2.8 flourite lens from Bert.
NGC4945, just 3x4 mins iso 200 uv/ir filter only.
Also a full res. crop showing the fine points if fainter stars, incredible resolution from this lens at just 300mm and at f2.8. Amazingly I was able to achieve focus after only taking 2 test shots of 5 secs each and adjusting focus each time.
Finally, an area in Centarus, this time with the UHCS as well as the uv/ir filter in. 2x15 minutes, ISO 200. The originals were so deep that even with the uhcs filter, the histogram was in the middle and sky background very bright. The "bright" nebula near centre is RCW 78
with a cluster called PISHMI H18, and RCW 75 lies off to upper left. Ive included a map from Star Atlas pro, plotting stars from the Guide Star Catalogue, at least I think thats how it goes, but the area is so crowded with stuff its hard to be sure.
