Looks back to front. Reverse the image then compare against a map. You will find it is Copernicus.

Did you have your star diagonal in place during imaging? Just count the mirror reflections in the imaging train; odd = reversed, even = non-reversed. SCT with star diagonal has three and without star diagonal has two.

Whether it's upside down or not is irrelevant, just turn the map around.

I see some very spectacular planetary images and image processing but the simplest of all is often omitted and that is to reverse the reversal.

Great image by the way. Well done!
