IDAS LPS-D3 Filter

[Mikey0368]

I currently use the Optolong L-Pro filter with my ZWO ASI294MC OSC but I'm thinking about replacing it with the IDAS LPS-D3. I'm on the edge of town (Bortle 6) and we're scheduled to get LED streetlights later this year.

Is the improvement worth it?

FWIW I live in a similar bortle 6 area with LED lighting and do not use any filters. I would rather deal with the gradients in processing but keep the maximum data. Admittedly I generally shoot mono, but it should not make that much difference. Also, the lights the council have used are quite downward pointing with less spread than the old sodium ones. So generally, for me at least, better.

Having said this, personally I would wait until they change the lights and decide then. It's coming up to summer and imaging will be put on hold until the autumn. The Optolong  L-pro does seem to remove most of the LED spectrum. (I think the LED spectrum used in the Optalong 'blurb' is specific - some of the spectra I have seen seem to be more broad). You never know, you might be pleasantly surprised. (LED lit cloud rather than sodium😂).
