A waxing gibbous moon

It’s been quite a while since A lunar tour from Earlspark Avenue so I decided to give it another go. We had quite a good clear night on Thursday so I set up the Mak 150 ’scope in the garden, ready for some more snaps at about 20:30. I began with 2 DSLR shots with my Canon EOS 500D to set the scene, stitched together again with Microsoft’s Image Composite Editor (ICE) to make a single image of the waxing gibbous moon.


Then I switched to the ZWO ASI224MC camera as before, still using the infra-red pass filter which is meant to give a more stable view, albeit monochrome (and with a bluish cast). Meantime the moon disappeared behind a tree, but it emerged again a bit later and I resumed at 22:00

Once again, I have used Virtual Moon Atlas to provide screen-shots for annotation, and also a description of the selected feature. But this time I have built them into a five image slider to save screen space
