"I preffer this sistem because it is lighter and with lower profile( vs. filter wheel). It is strong and reliable,too. I think I'll buy another drawer, in order to have the next filter ready for change. But, there is a problem. The female T thread (telescope side) has 2mm length. The 2""/T2 adapters have a large variety of T thread length(MPCC has 5mm). If the thread is just a little longer than 2mm, you cannot insert or extract the drawer because the back wall is too fixed. Well, you can use tuning rings to have that 2mm thread length. I preffer to have the male thread 1mm longer than female, just for safety. Solution: just cut 1.5mm(or what you need) on the edge of back wall of the drawer ( with 42mm length)."
