Visibility III / V
Delta Cygni is a cramped twin star in Swan in the middle of the Milky Way. Its components have magnitudes of 2.87 and 6.37 and their angular distance in the sky is close to Finland's winter seeing limit, ie two angular seconds (2 "). A larger image of this item will appear on my website and those percentages in the corners of the image are the scaling of the image from the original 100% image.
I have acquired a second lens telescope for my incoming season, especially for visual observations (TS 102 / F11 ED). The current TMB 152/1200 (LZOS) APO lens tube now remains largely in shooting mode without disassembling its camera for visual viewing. Each tube sees at approximately the same location in the sky and typically in the same size field of view.
In the optimal situation, I can now effortlessly visually observe the object of observation with that 4 "F / 11 lens tube and then take a photo of it with the adjacent 6" F / 8 TMB 152/1200 lens tube and my ASI 183MM Pro camera.

The second image shows a night view of my backyard captured at the end of the observations. I personally find it sensible to move my selection of subjects somewhere other than deep sky subjects. Such brief, two-star observations allowed by a rapidly coming observational situation are one example of this transition.
