Excellent.

I think it will provide some nice contrasty views.

Don't know about knocking the orange glow from the FOV, but it should be interesting - especially for astrophotography.

Alcohol makes winter observing more tolerable.

I like Zhumell products, and although not the top end of astronomical equipment....I trust their line of goods.

It will be a fine acquisition...email says that it's on it's way.

I am...this close to getting the 0-III filter, but holding out if they slash the price.

There are some band filters in my eyepiece case, but in the 1.25" size....sometimes they are good, most times not...but good to have them anyway.
.

No, still in the Zhumell line....the others are way too expensive.

A Zhumell 2 inch High Performance Ultra High Contrast UHC Filter

and a Zhumell 2 inch High Performance O-lll Telescope Filter.

Economical at $49.00 each....but I'm hoping they will be cheaper soon.

Primary test of the Sky Glow Filter....

It's been pretty much overcast since this filter arrived and anxious to try it out, I bundled up on a cold Chicago night and set up outside of the garage for some quick testing...



Electing not to set up the C11 beast, I grabbed the smaller tripod mount and the 90mm refractor - setting up with the 2" right diagonal. Observing Jupiter in a 25mm 1.25" Plossel with 1.25" adapter, one could easily see the ghastly orange hue of the light polluted skies over the city. Flicking the filter lens back and forth between my eye and the eyepiece, I could see that this filter made for a darker FOV and limited the orange glow. It lends a slight purple-ish hue to the object, (in this case Jupiter), but also brings out nice contrast in the Jovian banding.

Slewing around the sky, the FOV was remarkably darker and light pollution glow diminished. Targeting the Moon now, I preferred the filtered view over the straight un-filtered view, as when removed, the lunar view took on a curious greenish tint - a play on my cones & rods.

I screwed the filter onto the 2" diagonal and set it back into the refractor and using the Zhumell Zoom 24mm - 8mm eyepiece, I was treated to a nice darker background and nicely contrasted lunar features and Jovian banding. The filter does diminish the brightness of the object somewhat, but not dramatically.

I also tried this filter out on the C5 SCT with similar results.

I am satisfied on this brief first test of the Sky Glow filter, and anxious to try it on the C11 and on Deep Space Objects.

Highly recommended... #Thumbsup#

More soon.

I am a resident of Oak Park that has recently resurrected my interest in star gazing with the purchase of an 8" reflector on a dobsonian mount. Since I am only four blocks outside of the Chicago city limits, the skyglow is rather intense. I was thinking about purchasing the Zhumell filter set and found this excellent forum while I was looking for reviews. Hopefully sometime in the near future I will be able to join you at one of your star parties, but in the mean time I was wondering what you throughts were on the Zhumell filter now that you have had it for a while.

Right now I only have 1.25 inch eyepieces so I am considering the See It All filter set from telescopes.com. It has the urban sky filter, an OIII filter, an UHC filter, and a variable polarizing filter all for $89. Compared to other filters, that is a steal.

I am glad that you have found the filter useful. I am looking forward to seeing more deep sky objects without the orange glow around them.

And yes, astronomy is fun. My older brother got a BS in astronomy and took me out to look at the stars many, many times in my youth. Back then we lived in a small farm town in Central IL where skyglow was unheard of. I am really enjoying discovering all the advances in technology that have occurred in the last 20 years. Having my iPad tell me the name of a satellite flying overhead is simply amazing.

Thanks for the recommendation,
Tony

Mojocvh...

Yes, the Skywatcher, the Orion Skyglow and the Zhumell Urban sky filter all seem to be equal in performance.

And I have to say I'm pretty impressed. Kills orange sodium glow and the effect on the reflections from a house wall are quite amazing.

Now some more stuff from the UK some may well have seen this already, apologies if so, but its well worth a looksie.
