I'll be putting together my ZWO 7pos EFW, with Antlia 36mm unmounted filters. Any tips to do this right the first time?
1) I understand there are different surfaces with antireflective coatings, so has to be installed in correct orientations. Is this just the SHO, or LRGB as well? Not much documentation with the filters. Website has an example but not specific.
2) The rings that come with the EFW to secure the filters have a smooth side and a roughened side. It seems to me that the smooth side goes against the filter so as not to scratch it?
3) I will blow dust off prior to sealing optical train.
