They are very impressive. After mucking around with a Quark in the past with some underwhelming results I recently purchased the Skywatcher 76Ha and the ASI678MM is a perfect pairing for that. I well and truly have the solar bug at the moment. Pleased to see if I go down the SHG path in the future it will serve a good purpose.
Also you must have a very special SHG, your image suggests it is taken on 20 Feb 2025, tomorrow
