QHY8L and focal reducer fitting

[duncanjameshill]

I now have my first AP camera -  a QHY8L. I have a SW 100ED with the 0.85 reducer which screws onto the scope in place of the diagonal (I'm assuming!) How do I connect the camera to the reducer 😂?!?! Obviously I need an adaptor of some sort, but what is it called?

Thanks,

Duncan

Hi

I think you need an M48-M42 F-M adapter like this https://www.amazon.co.uk/Astromania-Thread-Female-Telescope-Adapter/dp/B01DIRJ72I/ref=pd_lpo_3?pd_rd_i=B01DIRJ72I&psc=1 , plus maybe some spacers to get correct back focus, but maybe someone with this setup would know more about that!

you need 55mm spacing however the chip in your qhy8l i think from memory is 12.5mm inside so youd need spacers of 42.5mm but where do you measure from on that flattener/corrector? im not sure, someone will know.
