I’ve made a lot of upgrades over the last year. The biggest upgrade I made recently was to make the jump to mono. This will have been my third camera upgrade as well (fourth if you count my initial jump from a DSLR to a cooled CMOS).
I first jumped from a Canon 7D (Unmodified) to a ZWO ASI071 MC Pro, then went to a ZWO ASI2600MC Pro and now finally a ZWO ASI2600MM Pro. This jump to mono required me to get a filterwheel and a set of filters.
This is going to be an interesting jump to a new chapter of imaging.
