How can I photograph Neptune's moon Triton with a BRESSER MikrOkular HD camera?

Please can you help me, I don't know how to overexpose Neptune and Triton enough to capture them with BRESSER MikrOkular HD. Is this even possible? Thanks in advance.

Not my area of expertise but these are going to be small. Check out astrobin e.g. https://www.astrobin.com/3my458/

The manual says:

"To adjust the exposure time individually, remove the tick mark from „Auto Exposure“ and choose a different exposure time from “Exposure target“.

You will need a very long focal length scope, such as the C11 in rnobleeddy's link.

Best you can hope to get is just two dots much like regular star in the image.

Neptune has about 2.2-2.4" of angular diameter - so even with very large scope - it will be only a few pixels across. Triton is about x20 smaller by diameter (24700km vs 1350km) so it will be less than half a pixel with even large telescope. No way to resolve it.

Neptune has magnitude of about 8 while Triton has mag 13.5.

Both are well within reach of long exposure astrophotography - ideally you want to expose for tens of seconds and stack multiple such exposures to accumulate at least 10-15 minutes of imaging in order to record both of these.

Thank you very much for helping me. I will check the link that you replied with.
