Description

This past Saturday was a snow storm day. Then, on Sunday, the skies cleared to a remarkable extent.
Good thing, too, as there was a Total Lunar Eclipse -- during a much-hyped-by-the-press supermoon - -here late Sunday and into early Monday.
This is a stacking of 10 images, taken in quick succession during totality. Location, our back patio in Oakville, Canada.
These exposures are all ISO 800 and range from 1s to 8s in length
Stacked and aligned in Autostakkert, then a touch of PixInsight to attack ‘noise.’
With the images collected here, during totality – where the Moon was amazingly dim – it was very difficult getting detail/fine focus. The stacking helped bring some of that detail out.

Canon T5i on the back of a SkyWatcher ED 600mm f7.5, atop a CGEM mount that was “roughly” aligned.

And let’s not forget this part … Ambient temp: -17.1C. Gosh, that was chilly ... but the CGEM performed flawlessly and without complaint.

PS: I collected images before the eclipse began and, of course, all way through to totality. Looking at the ISO speeds of the exposures and the exposure times, I was able to roughly assess the “difference” in the light on the Moon at these two extremes. Depending on whether you go from bright supermoon to total eclipse, or the other way around, the difference in illumination appears to be in the range of 1/8,000th or X 8,000. Amazing.
