An interesting comparison of full disks here; both of the sun at roughly the same time, but taken with quite different setups. The first is taken with the triple stacked 40mm scope at 700mm focal length, the second with the single stacked Daystar Quark with a Baader TZ4 telecentric on the Skywatcher ED80 at a focal length of 2400mm. The resultant views are quite different, and with the second the Quark was on reflection not properly on band. Now I have the stock telecentric on the quark replaced with the TZ4 the aim will be to double stack this setup and try a full disk like that, which, if it works should give some interesting results! Camera used was the PGR Blackfly GigE IMX249.
