Hello Cloudynights community! Yesterday I started a new topic about IR astrophotography. Well I've seen lots of amateur imagies taken with infred filters for deep sky. So, I wondered; What is the best(relatively cheap) filter for Infrared Deep sky Astrophotography?

 

Thank you Clear Skies!

Told you in the last thread, you can use near infrared photometric filters, be it JC I, or Sloan I or Sloan Z.

Really it was that easy? Thank you!

Yes but keep in mind we are talking about near infrared wavelengths not infrared. Due to the atmosphere you can’t image in infrared. I use a Sloan I filter and it showed some red cool (as in low temperature) stars that are otherwise not visible and that’s about it

Oh that's really cool. Can I see somewhere your imagies?

If seeing more stars instead of nebula is interesting then go for it.

Well I like to see the universe with different eyes;https://www.astrobin.../full/gw70gu/B/
