Cloud meant I missed the very start and very end of the eclipse, but I did get the bit in the middle on the whole, which, is the important bit I guess. It was my first opportunity to test the double stack on my SM60, it was literally setup for the first time 30 minutes before the start of the eclipse. It seems to work well though, and the next step with it will be to see if the double stack etalon benefits from the compression mod, which worked really well with the primary etalon of this setup. 500 frame exposures were taken, with a 3 second gap between, resulting in an animation of over 200 total frames. Setup was the Coronado DS60 at f11 with the ZWO183mm camera.

Sunday Sunshine 9th March
Sundays skies were hazy, very hazy, but with variable transparency which made imaging difficult. The seeing was pretty decent though, and I think I have achieved my best resolution yet with the Coronado SM60.
Absolutely love this scope, it has an etalon with good finesse, and after the compression mod is completely even across the disk.

Ha FD Coronado DS40 - 8th March
It's taking quite a bit of work to get a usable image out of this little double stacked Coronado scope, but, I think i'm getting there with it. Experimenting with the order of the etalons, compression and tilt tuning, and a new DERF has resulted in improvements. Possibly still more to go too!
Ha Sunshine with the Coronado SM60 8th March
This is a lovely scope for Ha, both imaging and also visually, high light throughput means a higher magnification can be used, and the 60mm aperture gives a notable improvement in terms of resolution compared to the smaller scopes. A very nice compact and lightweight setup!
G-Band Sunshine 8th March
Taken with the OTA from the Coronado SM60 and the Lunt 1.25" wedge with the 430nm G-Band filter. First go of this as a white light setup to be used as a portable setup. Pleased with the potential of it as a patrol scope!
