What kind of filter do I need?

Recommended Posts

Hi there,

I have a DMK21AU04.AS mono camera which I wanted to start using for planetary imaging & I was wondering which filter I would need. I already have a IR pass filter but I was wondered if a IR/UV cut filter would be better?

Any advice is appreciated.

Cheers,

Jeff

For a mono camera you can do lunar imaging with the IR/UV cut filter. A set of R, G, and B colour filters (in a wheel) are necessary for colour imaging of planets. Some use the IR pass filter to create a luminance channel (IR is less affected by seeing).

Hi Michael,

Thanks for the advice. At the moment I'm not using any colour filters & I'm just using the mono camera on its own so which of the 2 filters would be best just now until I buy a filter wheel & RGB filters?

      Selling my LRGB filters 36mm unmounted , because I decided to use only my Narrowband and to invest in something else that I want.
      The filters are placed inside my Atik EFW2 at the moment but I can send photos if someone is really interested , so I don't loose my cc'd setup position.
      Are in excellent condition ,sold in their original boxes.
      The filters are well known so not much words need to say.
      Some info you can find here at Astrodons site:
      https://astrodon.com/products/astrodon-lrgb-gen2-e-series-tru-balance-filters/
      The retail price is about £800 if I am not mistaken I will sell it for £500..............£375
      Other offers can be accepted within reasonable price 😀
      Payment via PAYPAL is accepted, buyer pays the fees.
      I post them from Athens Greece in A class shipment secured.
      I will pay the postage expenses.
      Thank you,
      Nikolas.

      Hi guys
      Can anyone identify which control box this is? Is it focusmaster? And does it run off robofocus driver in Indi lib as I cannot get a successful connection (in indi within ekos) 
      I bought a robofocus motor with this control box second hand. 
      I have faith with seller that hardware works as should. 
      I've tried other cables and USB ports too. The software (k stars) I use does do port search when connecting equipment.. 
       
      Any help appreciated
