Today's SUN (20180330) | Coronado SM90II again

WEBLINK:

The Coronado SM90II was used together with the LUNT152 for the first time today. As it turns out this etalon works perfectly with a focal ratio close to F/10 (matched BF15). I only used it visually. Check out the some setup images below

A new small AR is coming around the limb

Thanks Alexandra

I'm glad that the SM90ii is not a large paper weight after all

Thanks Eric

Hope your SM90II will be OK after servicing. I got an excellent definition with mine today (visually), many small proms and surface details

Thanks Mark

I will give a go asap. It's raining here for the whole week

I mentioned before that we needed the rain desperately. March was the wettest month since 1932 in Portugal
