Hi All,
haven't imaged anything for a while as we've had sunny clear days but clouds coming over at dusk!
Anyway last week there was one night that broke the pattern so I decided to test out a new wide-field setup (OK most of the equipment is not new just the combination is new
).
What's old: Samyang 135mm lens, ZWO 2600mc, Antlia dual-band filter and Vixen SP mount (very old circa 1985
)
What's new: Astrodymium 3D-printed rings for the Samyang lens & ZWO filter-drawer / EOS lens adapter combo.
I still have some unresolved tilt issues I think (which are even worse at f2.8) causing radial flaring across the LHS of the image. I was able to crop out the worst of them & do a little star-fixing but it's something that still needs to be resolved. Exposure 48 x 2min at f2.8 under Bortle 7 skies. Despite the filter there were still significant gradients to be removed which I guess is to be expected with such a wide field in light-polluted skies.
Anyway here is the image and a higher-res at
astrobin
