Light pollution clip filter for Canon eos.

[Guest]

Hello.I have just bought a Canon 100d dslr.I donot intend astro modifying it.But I do want to do some astro photos and would like to buy a clip filter.I understand that a normal light pollution clip filter is for use with a modded dslr. Can anyone suggest where I can buy a suitable clip filter please.

In my experience you are better off without an LP filter and then attending to the colour balance in post processing. LP filters remove a lot of your desired colour data too.

I've used both the Astronomiks CLS and Hutech IDAS LP filters in-camera filter systems.  Personally I much prefer the (more expensive) Hutech filter.  It affects the colour balance far less and hence makes processing easier.

I've also been looking at these clip filters.

The thing that is putting me off buying one is you are restricted to using just EF lenses because the EF-S lenses go into the camera body to far to use the filter.

An efficient meridian flip is your best weapon against light pollution along with the DBE tool in Pixinsight.

Can you explain this please (the meridian flip, not the pixinsight). I can't for the life of me work out what difference a flip would make. If you're pointin at m45, you're pointing at m45 no matter what side of the mount your weights are on.

My apologies, the tone was a little flippant. 

The higher the altitude of you chosen target the less invasive light pollution becomes (less atmosphere, less particles, less reflection of LP). By extension your best subs will be taken close to the meridian if you are under heavy light polution (such as myself) so you will miss 50% of you're optimum opportunity if you don't flip. 

IMHO the best solution to AP light polution chose a suitable target near the meridian and flip. If you wish to image the Triffid or Eagle, go to a dark site.

I use an Astronomik CLS clip filter. I've not had any issues with the colour balance (I let DSS generate a custom white balance and combine that with RGB Channel align does the trick), the subs are blue tinged but the stack nicely sorts that out without me needing to carry out any further adjustments in PS. Nor have I noticed a lack of colour in my images with it.

Sorry about the you're/your.

Thanks for your explanation, I didn't find your post flipant, I was just confused by it. I too use a cls clip filter and it's massively increased the length of my subs, I like it a lot

No problem, it is each to their own (forums would be very dull if everyone agreed). For me personally, pulling the clip filter out of my canon markedly improved my final images, the subs looked awful but the proof is in the pudding.

I use an astronomik CLS clip filter............there great.

i also at times use light pollution clip filters, but there is no substitute to a dark site unfortunately you can not always be there. so when imaging from home the filter is on even when i do image at the meridian, as the skies are still pretty poor.
