The surface of the moon – as photographed today in the afternoon with a new lens which I recently bought on ebay and just received two days ago: an MTO-11CA from the russian manufacturer LZOS (built somewhen around 1992). This mirror lens has a focal length of 1m (!) and for this image I used an additional 2x teleconverter on my OM-D E-M5II to see how close I can get.
In order to reduce the atmospheric distortions I stacked 16 individual images (camera set to burst mode) with the free software RegiStax, so that the fine features around the crater areas are enhanced. Additional color fine tuning was done in Lightroom.
All in all, the process of capturing and post-processing the image was really fun (this huge lens also draws some attention from interested bystanders) and I am quite satified with the result.
Edit – 28/04/18
I want to add one more image from the same day taken @ 1000mm focal length without teleconverter. This image was also stacked from several exposures do reduce distortion.
