Dust cover solar filter SL 8" Dob.

[matelot]

Hi, all. Following on from the above and some advice to ask here as well - and rather than necro an existing thread - would appreciate thoughts on the points raised. I also had it in mind to make a maximum aperture (leaving a generous lip) out of the plastic dust cover for the remaining Baader film, with a mask on top with a much smaller aperture. The mask could be replaced at will with various apertures to see how things pan out over time. The rigidity of the dust cover should suit fine.

Advice appreciated.

Cheers

John

Your seeing will probably not stand a full aperture filter bit but make it as big as you can with what you have left over , don't restrict yourself to the tiny 50mm cover.

There's no need to worry about spikes either when solar imaging ... 😉

Thanks, Steve. No problem with 'slicing' up the dust cover? Seems the easiest and logical option. It's smooth without any manufactured smaller apertures - just going to cut the requisite hole to accommodate the film remainder.
