Hi all
I believe I will be coming into some money soon and was planning on purchasing the much vaunted ASI2600MM Pro.

I currently have a optilong l-enchance 2" filter that I'm using with an unmodded DSLR.

I was hoping to slowly build up a high quality 2" filter set of LRGB plus three narrowband filters over time. This is due to wanting to "invest" in 2" and probably not having enough to pay for the 7 position filter wheel and 36mm filters than get packaged as an option with the ASI2600MM Pro.

Anyway to cut to the chase I was looking to buy some cheaper 2" LRGB filters probably from ZWO and use a filter draw.
My scope is a WO GT-81 and the optilong filter is screwed into the flatterner.

So what are the issues with stacking filters like this? I'm expecting some reduction in sensitivity but is it AP suicide?

Also I'm expecting filter drawers are a PITA but if the exposures with one filter are 2+ hours then changing them out 2-3 time over the night doesn't seem too bad.

So any comments suggestions are welcome. Is it worth stretching to invest in 2" filters??

My fallback option is to buy the camera initially and then save up for the filter wheel. Bundling doesn't save too much.
