light pollution filter for the 6dmkii?

Does anyone know if one of these exists or what my next best option is? Wanting to do some milky way shots from the backyard in the middle of a city of course.

The only effective filter I know of is distance.

There are actually several. Google "light pollution filter astronomy" and you'll get lots.

nope.

i should specify a but further. clip-in filters. Looks like astronomik is the only one however doesnt state if it works with the mk2

As mentioned the Astronomiks CLS for Canon is the filter uou need but here’s a link , you can call them and ask if it will fit your camera .

There site seems to indicate that it's for crop cameras given their list is all crop, but poking around a bit, some have said that it works in a 6D but vignettes around the corners.

If the clip in doesn’t work you can get lens filters however they are expensive .

Poking around that site I found this. Seems they have a FF filter after all.

yes the clip filters dont work and are for apsc cameras.

the 6d one is the only one. ill have to ask if it fits or not.

Astronomik makes clip-in filters in sizes to fit either Canon APS-C or full-frame.

The "catch" is that if you use a Canon APS-C camera then you can't use "EF-S" lenses. The rear-most element of an EF-S lens slightly protrudes into the camera body and would hit the filter. You can use the APS-C version of the clip in filter if you use "EF" lenses (they don't have an element that protrudes into the camera interior like the EF-S lenses).

But honestly...

You REALLY want to get away from the light if you want Milky Way shots. These filters improve things, but they don't perform miracles.

The are broadband filters that block the sections of the spectrum mostly associated with the emission wavelengths of Mercury and Sodium lights. Until recently, was the most common source of light pollution. But now that cities are switching over to LED street lights... these filters aren't nearly as effective.

The other thing about the CLS filters is that they do NOT block the wavelengths associated with deep-sky emission nebulae such as Ha, Hb, OIII, & SII. But the Milky Way isn't an emission nebula... it's stars. And stars are black-body radiation sources (full-spectrum light) -- not narrowband objects. This means when you use a CLS filter, you're blocking quite a bit chunk of the light from the Milky Way itself.

For the best odds at a Milky Way shot... get away (well away) from urban light pollution and do this on a clear moonless night (e.g. check the calendar for the 'new moon' and pick a night near that) and don't use a filter.

I think ive moved on from the filter idea. Bought myself a monocam and will use filters.

If Clip in ones aren't suitable for your camera then you can try Nisi, they do screw in and Square mounted types - but of course these may be limited by the lens you are using

and Skytech also do Clip in filters similar to Astonomik

I found a super cheap canon T3i and just using a clip in filter for that camera as its easier to find and compatibility is gauranteed. Plus it gives me an extra 1.6x boost in focal length.

Would love to see some shots with this setup, preferably with and without the filter ?

Living close to London,UK my skies are heavily polluted and having similar Camera would like to see how the LP filter performs.

people say minimal effect. i assume it will just allow me to do slightly longer subs and with slightly less gradients (the photoshop Gradient xTerminator plugin is a must have). i havent had a clear sky for months so i havent been able to go out with my new setup. I really got the T3i mostly for that extra 1.6x reach and the fact it is a lighter load on my mount

there is this guy https://www.astrobin.c​om/263253/H/?nc=user has done many excellent results with a dslr under rather high bortle skies. look through his gallery and see what hes got. very inspiring
