No sorry Dave, I only have the UHC equivalent Celestron LPR, I have used O III Ive used Lumicons UHC and O III they both would be most used making great improvement. On planetary nebs OIII and the UHC and LPR make huge improvent on imission and reflection nebs even at a Dark sky as well. Ive also used the Lumicon H Beta works for the Horse head neb with a larg scope, the only use for it that I know of as yet. What do you think Dave ?oh yes these are not cheap,you would be looking at 400.00 au for the 2"and round 200.00au for the 1.25" ones
new!
