Z3roCool Posted September 3, 2018 Share Posted September 3, 2018 Hi there, currently have a Canon 7D (Not Modded) and Canon 400mm 5.6 lens. Off to Morocco hopefully in the New Year. Should be pretty dark sky (Heading to the Sahara). When at home have Bortle 3-4 sky. Looking to see if I would benefit from a snap in filter for my 7D. Not really clued up on these at all. Is there anything that would improve pictures, allow for more Ha etc. or does that really need my camera to be modded? Thanks for any ideas.

Anthonyexmouth Posted September 3, 2018 Share Posted September 3, 2018 im in a 3/4 area too and noticed much better longer exposures with an astronomik cls filter. Link to comment Share on other sites More sharing options...
8472 Posted September 3, 2018 Share Posted September 3, 2018 (edited) Mod your camera, and get a OWB filter for daylight use. Best of both worlds. Edited September 3, 2018 by 8472 Link to comment Share on other sites More sharing options...
Anthonyexmouth Posted September 3, 2018 Share Posted September 3, 2018 ive seen clip in OWB filters for cropped canons but i was told not to use a lens with my filter in as it can hit the filter. Link to comment Share on other sites More sharing options...

Can't remember which one it is Canon EF or EF-S, but yeah one of those lens types has the extra "bit" on the end of the lens that could hit a filter.

JamesF Posted September 3, 2018 Share Posted September 3, 2018 It's the EF-S lenses that you need to avoid to the best of my knowledge. James 1 Link to comment Share on other sites More sharing options...

Shibby Posted September 3, 2018 Share Posted September 3, 2018 Just thought I'd add that you can also use a custom white balance to correct the colour. I have a 50% grey card that I take with me everywhere for this purpose! (It's a cheaper option than the filter) Link to comment Share on other sites More sharing options...

(It's a cheaper option than the filter) True, that's the previous way I did it and it's great for static subjects, but I soon tired of doing that for constantly changing lighting conditions and moving targets.

Adam J Posted September 3, 2018 Share Posted September 3, 2018 I would not even think about filters, first get a modified camera that difference is much larger than any filter can make. Even a 450D will outperform your expensive full frame if its modded. Link to comment Share on other sites More sharing options...
