Quick question: how attach filter to coma corrector?

[BrendanC]

Hi all,

I thought I wanted a clip-in EOS filter because that was the best way to fit a filter with my EOS1000D and Skywatcher 0.9x coma corrector (see https://www.firstlightoptics.com/coma-correctors/skywatcher-coma-corrector.html).

However, I just thought: is there a way to attach a much cheaper 2 inch filter to the coma corrector? For example, this: https://www.banggood.com/SVBONY-2-inch-CLS-Light-Pollution-Broadband-Filter-Suitable-for-Visual-and-Astronomical-Photography-p-1688255.html?cur_warehouse=CN

I've noticed that the coma corrector has a thread both internally and externally, neither of which would change the focus distance. It would make sense that a 2 inch filter might simply screw into either of these threads quite nicely.

Can anyone who uses this coma corrector with a 2 inch filter confirm or utterly refute this?

Thanks, Brendan

The 2” filter will simply screw onto the end of the CC

Thank you, I should have been more observant!
