That being said it is touted as being a lot cheaper than the coronado models and perhaps as good too. With solar scopes though the larger you can go the better. This of course means more expensive. If you really want to get into Ha you need to get a minimum of 60mm objective. You just miss out on so much detail with the likes of the PST and 40mm objectives. They are ok for a look but 60mm is like triple the viewing value.

Also you need to consider that a 0.7 a instrument is not enough. The bench mark for serious Ha viewing is really 0.5A. Anything less than that you are missing out on a lot. Especially during this time of low solar activity. The features are so much smaller and having a low angstrom instrument makes all the difference.
is that where this 12mm blocking filter comes in?
