LPS filter for Atik 314L+ color CCD

[javajunkie2121]

Hi All:

I have the Atik 314L+ color CCD.  I have medium light pollution..any suggestions regarding a LPS filter for the camera?  I don't think this camera has IR filtering..not sure yet.

You're right, the camera doesn't have infra red filtering built in.

I would suggest a Hutech IDAS filter for your light pollution. FLO stock them and they also block IR.

I agree with Rob IDAS are the best.

Which would be a better choice, the P2 or D1 type?

Does it make a difference which you choose if you have a mono camera rather than OSC?

I have both and I can't detect a difference TBH. IDAS filters are good but they are not the only choice and very expensive, depending on the type of the target you can use a Narrowband LPS filter such as the Baader UHC-s L Booster or even a Baader Neodymium. The SW LP filter has very similar spectral response curve to a Baader Neodymium and is less than 1/2 the price but I can't comment on the coatings use, neither are IR blocked.

P2 for mono. P1 for colour as the P1 cuts into NB too much for mono.

Edit: if you intend to leave in front of a fully loaded FW of course.
