You didn't mention the mount. Long subs for narrowband demands a good one.
There aren't a lot of mono cameras.
This is an economical choice. Has some quirks, many great images have been done with one.
Somewhat newer, still some quirks.
If you can swing the cost, this is significantly easier to live with. Few, if any, quirks. I'd recommend it, but I have no clue whether your inexpensive scope could handle the big chip. If not the price is something of a waste of money.
The pixels on the 183 mono are awfully small for that scope, will be a headache. I have one, don't recommend it for you.
