So heres an interesting question:

https://www.baader-planetarium.com/e...stian-voltmer/

This shows an image taken with a Fuji XT3 on the front of a RASA 8, but if you look closely there are 90 degree diffraction spikes in the image... which made me question if this could have been taken with the Fuji? I thought those kind of diffraction spikes are created with dedicated astro camera power cables split at 90 degress, and not a fully self contained mirrorless camera body. Odd right?

Also, I can buy a T-2 Fuji wide-adapter that is 8.3mm thick, along with the Fuji back focus of 17.7mm brings this distance to 26mm, however the RASA 8 back focus is only 25mm (so im 1mm too long...) which is why i looked closer at that image in the first place. However there is a clear filter inside the RASA which im hoping adds that 1mm.. does/can this happen? The article does say to leave that in, so im hoping for the best really...
