Big proms 290908

Another go with the DMK21 and 2x Cemax barlow. Lots of small proms today but these two big ones stole the show.

Using my new Cemax 2x Barlow

200908 fine proms

I caught some very fine proms today. I had to over expose the main brighter prom to capture them. These images all look similar, but look closely and you can see the changes. All taken within 10 minutes of each other. Quite active indeed!

These two image were taken 20 minutes apart with a DMK21 and no barlow. The change in the prom in this short period of time is very obvious.
