Hi, I would appreciate any help on the topic of "What filters to use for Imaging"? I already have red,green yellow and blue filters and need info on what to get for deep sky imaging,1.25" or otherwise.If there are any out there that are reasonably priced? I have heard of using the color filters in deep sky imaging to where you would take each image with the individual filters and then stack so as to bring the colors out in the nebulosity , if that is a word.Is this the case or not?Would love any and all advice on this subject and if anyone has filters for sale at ofcourse a reasonble price, let me know. I am not sure what to get. I have a Canon T4I and will be using my Celestron 8se with a Meade focal reducer/ corrector for prime focusing as well as piggy backing the camera on same or using my Celestron 90mm maksutov scope piggybacked on the 8se for imaging. So have plenty of options. Also what filters would you use for prime focus imaging and how would you attach them to your camera using the focal reducer/ corrector attached to the scope first?

Celestron 8se
Celestron 90mm mak
Celestron 70mm 400mm fl refractor

Celestron bino viewer
Meade 6.3 focal reducer/ corrector

You don't use filters with a colour camera, filters are for astronomical MONO cameras

DSLR cameras don't need as many filters as SLR film cameras, especially if you shoot in RAW.
There are some filters though that I think are important to have with a DSLR. Number one is a Circular Polarizer. The CP filter can eliminate glare and reflection off water and glass. It can also darken a blue sky and make the clouds stand out more.
Depending on where and what you shoot, you may want to consider a Neutral Density and/or a graduated ND filter.
I like to keep either a UV or a clear filter on my lenses to protect the lens glass. I will take those filters off first if putting another filter on.
When buying a filter, some things to keep in mind are: Get filters made of glass, not plastic or polymer. Get brass threads. Get one with multi-coating (MRC).
The best filters aren't always the most expensive, but cheap filters are cheap filters.

But the question is regarding ASTRONOMICAL photography, so your reply is not related

Useful and helpful post "NOT" Scoutman, perhaps if you can help that would be of more assistance

Clearly he WAS asking about filters, and anyone who "reads" the post will know what he is asking, I DID

NOT having a go at you Mac, sorry.

Hi,
Let me try and help you. The colour filters you have can be used for b&w astronomical imaging.
or colour imaging I use a H-Alpha 7nm (not to be used on the Sun - different HA). For viewing I use an O III.
Have fun.

Hi, I did not mean to start anything on here. I guess in the future I will try to place a better heading question. Scoutman sorry,JR1 thank you for your replies. IamPJ I appreciate any info that will help with my endeavors. I am new to imaging and fairly new to this site yet not to astronomy as a whole. I have built 3 telescope in my time. My first was an 8" f/5.6 dobsonian, my second was a 12.5" f/6 truss tube scope of which I built my own clamps for the poles that separated the mirror box from the upper cage. The last I just recently built is a 6" f/4 newtonian scope of which is a whole different story. So don't think that I am a complete newbie to the game here. Tim
