As far as I heard from their yahoogroups, we will have:
1. 50mm Sodium (!!) filter: notice that it would not be a regular product, so you will need to contact them if you're interested.
2. 75mm filter set: we were told it's coming soon, I really wish to see how the obstruction will look like, and how does it perform
3. 35mm front etalon scope: this should be interesting for those who wanted to take fast full disc shot, it has only around ~200mm focal length which should be great for this purpose
With the recent price reduction from Coronado, I believe the narrow band solar instrument market should be very interesting in the coming few months.
