UHC Filters

[StarLane]

Went to the Leyburn dark sky site for a night of observing on Friday night.
I was surprised at how much better my UHC performed compared with it`s performance in the backyard. I knew it would work better on a dark sky, but it just blew me away, especially on the Carina and Lagoon nebula and even the Tarantula nebula. Lots of other targets just stood out. First time I have viewed at a dark sky site since I have owned this filter.

Solanum,

As Geoff indicated a Narrowband filter works best from dark skies as opposed to light polluted skies. If you already have good sky conditions you will get significant improvement on a lot of nebulous targets with a narrowband or UHC in your 10" dob.

The DGM NPB filter is a very narrow pass band, narrowband filter. It is almost a hybrid between a UHC and an OIII filter. I would recommend you consider this filter for use with your 10" dob.

Tell you what, it's a quick mail-out from the US of A! My filter has arrived...at the same time as the lousey weather...dang! Hopefully there will be a little bit of clear sky before I head off on holidays with the family...and leave the scope behind at home.

The weather in Brissy the last two days reminds me of my last posting to Victoria - cold, cloudy, bleak, but...with the promise of snow in the high country. Unfortunately we don't have ready access to the snow in Brisbane...ahhhh, such is life...the ice skating rink is just down the road, though.
