The postman was kind to me today and dropped off a William Optics Zenithstar 61 and Flat61A flattener and the gods smiled on me with clear skies for 30 minutes. It would be a shame not to christen the new toys
I only managed 10 lights so I didn't even consider darks or flats. The 10 lights from the Canon 5D MkIV, shot at iso 1600 x 60 seconds, were stacked and aligned in PS, median filtered for some noise reduction and then a few layer/curves tweaks to pull out some basic detail so I could look at the star profiles and and any vignetting.
Overall impression is extremely good build quality and the focusing through the mask is ok on very bright stars but quite a challenge on lesser star magnitudes. Very little vignetting through the imaging train so the image circle cover the full frame sensor and it will be simple to either remove the gradients in PS or use flats and sharp stars corner to corner with no obvious colour aberrations.
I do need to check where the weird smudges are in the imaging train because they weren't on the camera sensor yesterday, hopefully I'll find them pretty quickly because they are nasty!
Screenshots are also included of APT focusing, Stellarium for the imaging area after plate solving in APT and then PHD2 for the guiding with the ZWO ASI120mm-mini camera on a ZWO 30mm f/4 scope (I've no idea if the guiding is good or bad but the polar alignment was achieved with the iPolar camera in the SkyGuider Pro mount
I think at some point I'll add an 2" IDAS D2 filter into the imaging train and see if I can counter some local light pollution we have around here.

Good day all,
I braved the cold (minus 25 degrees Celsiuss) to finally image this phase. I realized most of my prior imaging was near full moons.
This required different techniques, so I am glad I got my chance. Backyard session lasting about 35min before my hands almost fell off haha.

Thanks for looking and clear skies!

I love trying new ways of processing. I tried flats first the first time (which failed to improve the images so I removed them). Today's Main goal was to try my first ever animation.
I am still going through that data and learning curve, so that will come later. But here are some close up shots taken with a TV 3x barlow.
This data was processed a bit more aggressively. I have softer versions available if you think there is too much noise on these.
Comments welcome, animation to come!
