Customer Reviews
Very new at this but what I can say is my first imaging session turned out pretty good. The filters fit perfectly inside my ZWO 5 position mini EFW. My imaging session was not the most colourful target.. The Sea of Crises, however the focusing was better than expected. Looking forward to capturing Jupiter and Saturn next.
