Rho Ophiuchi cloud complex
imaged from my astronomy club dark site at Linden, Blue Mountains, Australia
Two panel mosaic- 5 minute subs, one and a half hours of exposure for each panel -three hours of total integration
Equipment
Samyang 135 mm / Optolong UV/IR filter/ASI AIR/HEQ5 mount
software
Astropixel processor/Photoshop CS6/ Topaz AI
Notes
AstroPixel Processor took almost three hours or maybe even longer !!! to stack the data and construct the mosaic as I had MBB and LNC (1 iteration ) turned on
Very disappointing to see the star shapes in the corners- I thought I had found a good edition of this lens- and have previously obtained photos with it where star shapes have not been a huge issue. What's different? not sure- the only thing that has changed is the filter - a UV/IR filter instead of a L extreme filter. Could this cause the problem ? not sure
the h alpha regions don't "pop" as much as maybe could be expected... maybe H alpha data would improve the image. Something to try another day
