Blessed with another night of super stable skies allowed some extreme high power viewing with sharp as a tack features shown. The first try after the 15" was collimated and cooled came with the 18mm UO ortho and the stable view indicated more mag could be used so in went the 7mm KK ortho (261x) and yet still exceptional skies. Over to the binoviewers we go and an hour or so of observing using the 32mm TV plossls,18mm Tak orthos, 12.5mm Tak orthos and finally the 9mm Circle T orthos at 487x or there about with the powerswitch. When the binoviewers support this high mag I know from experience mono will go more- in goes the Vixen HR 2.4mm for 761x and the scope/sky easily supported this tonight. The combo can use more, maybe the incoming 2mm HR will work, but I wont hold my breath as this is a huge jump in mag. So far I have not reached the limit of this scope and seeing however-761x is used frequently at certain times of the year. Now Copernicus and its batlike shadow that presented itself tonight. The mass of ejecta surrounding this crater is amazing, with its fine cut radial pattern all around. The crater's inner ledge of material was a standout and the Vixen pulled out some very small "boulder like" features on the smooth side of the central "mountains". The other side had much more material and was much more detailed but the HR 2.4mm pulled out those really small features on the other side, what a nice find actually. That shadow was impressive tonight, hopefully it comes round again like that someday. Tonight was a great observing night indeed!
