Whilst visiting family in NZ last week I got the chance to spend a few hours doing a dark sky astrophotography session with my brother near the base of Mt Hutt ski-field. One of the goals was to create a 7x7 high resolution mosaic of the region from the SMC to LMC to Carina to the Pointers, something I haven't been able to do around my home region of northern NSW do to its high latitude. (I havent worked out how the 50th image snuck in there)
I used a Canon 6D with a 135mm Samyang F2 at F2.4 with a panoramic ballhead on top of my Star Adventurer EQ mount.
AstroPixel Processor did an incredible job of blending the 50 images in one run, but I had awful blending lines due to vignetting.
So I put the camera and lens in the fridge yesterday for a while (which I figured was a good approximation to the 5 degrees we were photographing in) and took a full set of calibration frames then reprocessed. The flats in particular helped immensely and I just needed a bit of help from APP's light pollution removal tool to tidy the blending lines up a bit.
Can anyone suggest a good place to host the full sized version ?
(Footnote: I managed to create myself an Astrobin profile and made this my first image)
