Hi all
It finally arrived this morning. I went for the clear filter option, like Houghys 300D.
The In camera noise reduction works well, a 5 minute test shot at ISO 1600 with lens cap on, noise reduction off showd many times more noise then a 10 minute shot with the noise reduction on. Only downside is doubling of exposure times.
Heres the first astro images I took with it tonight between gaps in the cloud.
Note, they are all single images , none are stacked multiple images. Just played with them a bit in photoshop and used noiseware on them, thats all
Thanks to Houghy for lending me his new Baader IR/UV cut filter too.
Scott
Thanks all.
Theres a fair bit of noise with the N/R off on ISO 1600 shots, but the in camera n/r is a Godsend for getting rid of most of it. Ironically with my 300D, Photoshop CS somehow gets rid of a fair bit of the noise (but not the amp glow) automatically when I open raw images with it, but CS2 does not, nor does it with the 350D, and sadly Adobe decided not to support the 350D with CS. So despite the xtra time I will always shoot deep sky with the in camera n/r on.
I should mention the the first shot is a 165 sec shot @ ISO 800, the middle image is without the UHCS filter, and is a 265 sec shot @ ISO 400, the last shot is a 193 sec shot @ ISO 1600
Nice Scott... Now you can give Houghy his camera back....
What's this about engaging your Hyperdrive Houghy... One could definately read that the wrong way
Cheers
Robby, I have had my camera back, complete with dribble marks from Scott for nearly a week, but it has been cloudy and terrible conditions. I haven't got the hyperdrive, read the post carefully Rob!.
Yes it shows the red, but wow, look at the details!!!
Thanks
The UV/IR filter was used on the 2 and 3rd shots
Scott
PS sorry about the drool marks Houghy
They're great shots Scott, like I've said already, I love them.
I'm just wondering why the use of the UV/IR filter for a modded DSLR?
Is that what's needed for modded cameras?
thanks.
Rocket Boy, yes the IR cut filter might stop excess IR light from coming through, however its mainly for refractors, as they focus IR light slightly differently, resulting in bloated star images if no filter is used. That doesnt happen with refector scopes.
