- Welcome back AstroAddicts!
I often get questions about which filters to use in which situation. That's why i decided to make a video on that topic, and answer the most basic questions regarding filters!

Thank you so much for stopping by, i wish you a wonderful day/night wherever you are, clear skies, and
May the night be with us!
Great run down, Tim! Good to see you back! Best wishes from Scotland! :)
Thanks for sharing your knowledge and experience.
I'm looking forward to venturing into astrophotography one day
Thanks Tim, this was a very clear explanation of filters
Very good video!!!!! Thanks!
Danke schön für die tolle Übersicht :-)
Brilliantly explained thank you
I appreciate your insight - very useful and broke down easy to understand - Great teacher!
Glad you enjoyed it!
As always a very good and informative video Tim!! Well done. I hope your imaging laptop get fixed and you keep supplying us with your great videos!
Cheers!! 🍻
Thanks.
That was an eye opener.
I don’t understand why using a narrowband filter on a no-moon night will make you miss out on many star colours. Surely it doesn’t matter when you use a narrowband filter?
Say we have an Ha filter on a moonless night. How many colors will arrive on the sensor? Just Red, 656nm, since it's a Ha filter. To get star colors you also need Green and Blue. Plus, good star colors have a wide spectrum of wavelengths, which is not possible with narrowband filters
Have you heard of kolari? Can you confirm if their infrared filters are good as well
No, I have not heard of them yet
A very helpful video for beginners Tim👍
Glad you enjoyed it
Danke Tim für Info,,,!!!
You're awesome dude. Thank you!
Thx for this information. Very instructive. ^^ BTW, maybe u can explain to us what are the pros/cons of using RGB vs Monocrome camera, for which targets are optimiced, money, accesories... It will be a good video if u do it.
Maybe in the future, that's a very big topic
You explain things so clearly
Such a helpful video, thank you. I own an optolong l pro and an Astronomik cls clip filter for my Sony a7iii camera and Zenithstar 61 telescope. I am always confused as to what filter (if any) to even use for any given target.
Excellent video
Hi! I'm new to this, but I'm trying to filter certain wavelengths with just a filter and a camera. This is not for astrophotography, but for post-processing. I have a Ø 67mm lens but I can't find these types of filters in this size. Specifically I'm looking to mount a 589nm wavelength filter. How do you mount these wavelength filters to a camera?
I've only recently heard of the Radian Triad NB Filter, nothing else like it I was told, but it costs $1000 ! Do you know of anything similar but not so pricey ? This would be for a DSLR - Telephoto set up. For the time being I'm just considering a light pollution filter. Thanks for great information as always !
Hi Tim. How about refocusing while using LRGB and Narrow band filters? If I get it right there is a refocusing to do while changing filters. My question is, do I need to focus everything on a bright star? If I use an electronic focuser, does the device focus on fainter stars? Please share your experience while shooting with monochrome, especially the focusing part. Thank you
From the bit I've read on filter wheels and EAF, you have a set offset for each filter for the focuser to adjust to, and the auto focus units tend to be temperature based.
Super.
I am very new to this hobby and using DSLR, Camera Lens, Intervalometer, Star Tracker for astrophotography from a Bortle 6-7 zone. I travel occasionally to dark skies but I wish to capture images of both galaxies and nebulas, then what is your suggestion should I purchase Broadband Filter(Optolong L-pro) or Multi Narrowband Filter(Optolong L-enhance)?
For galaxies, the best thing you can do is travel to dark skies. Galaxies can shine in all different colors, using strong filters will cut a lot o good light away. I'd recommend to travel to dark skies, and use a broadband color filter, like the L-Pro. For nebulas, you can go for the l-extreme, and don't need to travel that far
I'm a beginner with telescopes with not much money, so I was wondering how the optical filters compare to using computer software filters if they exist?
An optical filter actually absorbs the wavelengths of light we don't want in our image. It's the best bet you have against light pollution. A software filter only sees sets of 3 float numbers, and can't possibly know how much of the components are light pollution. There are still software methods to reduce the effect on the overall image, but your best choice is to get away and filter light pollution altogether
Great content as always Tim! QQ, I saw the SVbony on your scope during the video and I am considering this for my new 10inch SCT RC for Galaxy work, what size mm scope would you recommend ? Thanks!! Simon
I've heard about a main scope/guide scope ratio of at least 1/10. Could be too small with a 10" SCT
Very informative video and very good explained, thank you. Question, how does the Astronomic CLS compare to the Optolong L-Pro ?
Is there somewhere a comparison ?
The CLS, in my opinion, is stronger than the L-Pro. The L-Pro will give you better colors, but processing will be hareder due to more light pollution
@@AstroAddict thank you
hi, why do some filters effect a glow around stars. in the corners this is more stronger than in the middle
I don't know of any deep sky filters that create a glow effect
@@AstroAddict ja ich habe Halos um die Sterne beim Cls ccd filter. Das ist unschön. Ein abblenden hilft nur bedingt
Das liegt selten am Filter, sondern am Objektiv. An hellen Sternen kann man Halos kaum vermeiden
Are there any filters that go in front of a regular camera not the telescope
I guess you mean a regular lens. Yes, there are. KaseFilters has ClearSky, and light pollution filters, that go in front of a lens
Fantastic explanation and execution.
