Well this Fuji GW670III is not exactly new, as I acquired it in November of 2022, but it’s been a while since I updated the toy section. You may have noticed the last two cameras added to my collection were rangefinders. While this technology has been around since the 1930’s, they fell out of favour in the 1970’s when SLR’s became all the rage. The Mk3 version of this lineup of huge neg rangefinders…

100 Solar Observations
I’ve been actively making Sunspot observations and submitting then to the BAA & AVVSO Solar databases since August 2022. But today, I made my 100th observation of the Sun. In the great scheme of Solar observing I guess this isn’t a particularly high number of observations, but it’s a milestone nonetheless. Things have changed over those 100 observations. The most dramatic of which is the accuracy and information recorded now. To illustrate this, there…
