Imaging the Magellanic cloud with extended red sensitivity! Who knows what we could see…there is so much potential for amateurs.

Nicely Done and congrats on the deep image and a great write-up! It is great inspriation to show what can be accomplished.
The quasar that Johannes had me image (and you mentioned and surpassed) was detected in less than 5 hours of exposure with a 6303E chip (pretty red sensitive). Johannes then combined the image with his 16" data to produce the pretty picture but the detection was done in one night from my backyard. He could not detect the Quasar from his site with the STL11k (not very red sensitive).
Here is the link to the 5 hours detection image that was tested. This is the quasar that you just surpassed.

With dark skies and great off the shelf equipment we can go very deep. The astronomers at the Max-Planck institute are measuring our 20" RCOS star streams down to 29 mag sq/arc. This takes about 6 to 9 hours of exposures with a clear filter to get that far.
The fact we own our own equipment means we can sit on a target as long as we want! That is our advantage over the "Pros" !!
Thanks again and a heartly congrats for such fine work.
Kindest Regards,
