DSLR filters?


Recommended Posts

Am looking for a filter system for Canon EOS 1000D to help filter out that lovely orange glow i get from living in such a hellpit.

Im hoping to use the Canon for both widefield shots just on a tripod,and when i get the adapters etc-Through a 5" reflector.

I take it i would need different filters for each?

Anyone have any recommendations as to which would be best to use?

Saw on one website that LP filters only make Nebulae more visible,and will reduce the visibility of stars,So i really dont want to buy something that isnt going to help.

(I ask far too many questions!)

Any advice would be much appreciated :icon_eek:

You need a Light Pollution Rejection (LPR) filter. It will significantly reduce the background glow, but unfortunately you get nothing for nothing, so there will be a loss of light overall....

Some imaging processing software has the ability to remove the background tint and make the image "look" better....

Re Filters - if you get a 2" LPR ( actually a 48mm photographic thread) you can, by using std camera step-up rings mount it on the front of your camera lens... you may limit the aperture, but a small price to pay. They ( the 2" filters) can also be used on any telescope which has a 2" focucer - so you could still use them in the future.

Jase, it all depends... Doesn't help does it :icon_eek:... I've basically used 2 filters... A Skywatcher LPR filter in 2" fitting. It works, and is relatively mild on the LP cut. On long exposures, over 10 minutes, the skyglow is working it's way back in. The other is the Astronomik CLS, both in 1.25" and EOS clip form. This is a very very effective LP block filter, even after 20 minutes, I'm not getting glow. It's a little bit strong on my f7.5 scope (works great on the F5 ST80 though...). It'll work a charm on my Nifty Fifty at f2.5. With the F5, I think the scope would be fast enough for something like the CLS clip to be fine, and would work well with EF lenses, it won't work with EFS lenses, as they protrude further into the camera body and the rear element of the lens will impact the filter. A simple step ring is needed to step from the 52mm filter thread of the Nifty to the 48mm of the 2" filter though.

Yes I got the Astronomik CLS clip filter for my Canon EOS1000 and I'd definately recommend it. - Aside from anything else, it helps to keep dust off the chip. The only thing I would warn is that the first time I fitted it, it was incredibly tight to fit - it's loosened up now though after fitting it a few times and it's fine. I've managed 15 minute subs here in Chester with serious light pollution. I just have to remember to get focus while I'm on a bright star as fainter stars don't show up quite so well in live view.
