Here is P10-2022-SNowflake012 and 013. same crystal different lighting. This was taken with 68mm of extension tube with my Plan 10X objective. What was in the RAW frame is a Field of view only 2.5mm wide, and the crystal is only about 1.7mm across total. Final version is always cropped in a touch to re-centre the crystal so this FoV is a little smaller than 2.5mm.
Small Plate crystal with a beautiful perfect circle in the middle. The clear version really shows off the bubble structure a whole lot better and it is amazing how symmetrical it is.
