Hallo friends, please advice me some limited but allrounder filters.

Hallo friends and starry eyes, I bought the Celestron Omni XLT 102mm refrator (1000mm focal lenght), 2" focuser. Just three weeks ago I bought it. Next I am planning to upgrade to all the 2" accessories. Prospects are - to do observation and photography of all Planets, deep sky, widesky, faint objects, and all those every possbile objects in the sky. So with limited budget for the filters right now, please recommend me good filters, that will do really good for bringing good contrast, sharpness, enhance colors of the objects, and cut the false color on bright objects. (I know these are common things that every astronomy hobbyist want. But for me, I want to bring out the best of the best out of my achromatic refractor). Please recommend any 2 or 3 filters that will do an all rounding job for me, for the purposes that I have stated above. Among the Baaders, or any other US brands. Good wishes, see you, sinerely Ketan.

Hi Ketan
Sometimes you need to be patient as there are a lot of new posts every day - sometimes individual ones can be missed.

There has been quite a few threads on discussion of filters in the past, a quick search will reveal the previous conclusions.

In general, I don't use filters but have found the DGM Optics NPB filter excellent for increasing contrast in some nebulas - but I wouldn't recommend it all the time. That's to say, the view is different - not better - with a filter. The best observing experience is when you see the object in a number of different "lights".

I would stay away from coloured filters which generally serve little purpose except to fill the eyepiece case unnecessarily. An ND filter for the moon is ok, but in general i'd recommend simply increasing the magnification to decrease the brightness, or let your pupil dilate more so it's not so blinding.

It's also worth noting that a 102mm aperture is not a lot - you're not getting a lot of light in in the first place. Using filters can have the effect of reducing that even more, making faint objects even fainter. So I would count filters as a specialist accessory that is not really necessary, but can be useful on rare occassions.

Dear Ketan
The only filters I ever use visually is a broadband filter that helps a bit with planetary nebulas and an orange filter to increase contrast on Mars. These would be used less than 3x/year.
You can probably get by with no filters with little loss in observing pleasure and spend you money on something that will get more use.
