Camera and Filter upgrade

[Z3roCool]

Hi there, just after some advise on what others would do...just to see if I am missing any options/ideas. 

Currently have NEQ6, Canon 7D and 400mm 5.6 L lens. Use scope and GPCam2 for guiding. 

I am looking at upgrading to a mono camera with, to begin with, NB filters. I have saved and sold some lenses and look to spend around 1.5k on the setup. 

My thoughts are an ASI183MM Pro with filter wheel (EFW5) and Astronomik 6nm NB filters. Will use the Canon to EFW adapter. Will be shooting around the 500mm and shorter focal lengths so the smaller pixels should be fine in regard to sampling. 

Does anyone have any ideas on what they would buy in my position? Different camera/filters etc.

Thanks for any input. 

 

Tom.
