Thanks for the explanation. Appreciate it alot :D In your opinion, would it be better to get a LPR like Celestron or a UHC like Orion/Lumicon/Astronomik? been trying to figure it out. I had ruled out the old Celestron LPR totally, since the review by quite a few website (users of it) was that it is ...

The Spectral Respond Charactersitics graph seems awfully similar to Ultrablock and Astronomik Professional UHC filter peaking at Hydrogen Alpha and Beta and cutting off the rest of the lights. Thus I am wondering what's the difference.

Hi Weixing,

Which one is the one you are having? The LPR or the UHC/LPR?

Anyone uses or used the Celestron UHC? How is it compared to Lumicon and Orion counterpart? Will appreciate your input ... .trying to decide on what to buy .

Anyway, if I bought a UHC, do I still need a Minus-Violet filter? I think it should effectively minus off most of the Violet, am I right?

haha....that is an artifact on the negative....something like a scratch...sigh. anyway, more about the image: it is actually a film image but cannot remember what film was used. But it should be Ektarchrome 200 which is unfortunately no longer available in Singapore. The Rho Ophiu. region is known ...

Hi blurlock, Which imaging software did you use? Registax? The stars in the background still managed to retain their natural look somehow. Really makes the nebula stand out. Nice! :) Cheers, :cheers: - ALPiNe Photoshop Elements. But which picture are you talking about? Some I use levelling, some I ...

nice try blurblock! anymore attempts? Sure :D ... there are quite a few methods, depending on the output you like .... maybe you can tell me what output you will like to see. Of course if you emphasis on one, you trade off with another. If you see everything, then it definately does not show the tr...

Hi, I think it's audio stories for only 10 M objects ... otherwise, you can identify and find 6000 objects .... I think it is really only 10 Messier object... Look at what it mention in the ad: "The SkyScout is a revolutionary, one-of-a-kind, patented handheld device that instantly identifies ...

Hee hee ... you're sharp ... I guess you're right ... hmm .... But ... when I look at it again ... I think they're saying that they will identify anything that can be seen with the naked eye - but not ONLY those - they don't say that they will not identify positions of things that are not naked eye...
