First Filter Selection

A friend of mine and I have been struggling with the decision as to what filters to buy. Our current thinking is OIII and Orion Skyglow in that order. We are interested in DSOs such as galaxies, Nebula, P-nebula, etc. There has been no opportunity to try someone else's stuff and our skies have been crap pretty much all summer here in NW South Carolina. Please advise.

What type of scope will you be using it in? I know that there are people who will have opinions in favor of one or the other, and some that will say neither. I am of the firm belief that you should get the Skyglow, but only after a good set of eyepieces have been acquired. I have used the skyglow filter and an 8 inch scope and seen the Veil Nebula from the suburbs.

None of the above. I would get the Orion Ultrablock first. I own , or have owned an Orion Skyglow, Orion Ultrablock and 1000 Oaks O-III filters. The Skyglow worked best on my 4.5 inch Star Blast. The Ultrablock worked best on my 8 and 10 inch dobs. As for the O-III, I sold mine as I didn't have enough apeture to use it. However I plan on purchasing an O-III in the future when I get my 14". Overall the Ultrablock will give the best results on the most objects. Get hold of the August? issue of Astronomy magazine, there is a very good article on various filters.

BTW filters all dim the view slightly while enhancing visibity of nebulas. They will not help at all on galaxies, as they dim stars.

thanks to all for the excellent comments. Have decides on a UHC and Sky Glow. Seems they provide most of what I am looking for in enhancing DSOs. Now only practice will tell.
