A QHY5, Wratten Saturn - not for the purists!!

[cybereye]

Hello!!

After the success I had imaging Saturn with the QHY5 I decided to give it another try. So last Wednesday night I set up the scope and started imaging Saturn again. But then I thought, wouldn't it be nice if I could get some colour into the image. And then it struck me - I had a set of Wratten filters tucked away in my Felix type bag of tricks.

Now before I continue with my tale, I should point out that I know this is not how you do LRGB imaging. I know that there are specific filters needed and that you can't use Wratten filters. I know, I know, I know.

But I did it anyway!!

So on with the story. I took one image without any filters - this I would use as the luminosity. Then using a 23A and an 80A for the Red and Blue channels I took two other AVIs. I then processed each of these in Registax5 and eneded up with 3 bitmaps that were stacks of 250 frames each.

"What about the Green channel?" I hear you ask. I'd read somewhere that you could synthesis this by averaging your blue and red channels. So this is what I did!! I then took all files into PS, bumbled my way through and somehow ended up with a "dirty" coloured image of Saturn which I present at the end of this message.

And once again - I know this isn't how you do LRGB imaging. But it was fun doing and I learnt quite a bit in the process.

Cheers,
Mario

You know what mario... brilliant, you have captured all the belts and yes thats right its not real colour, but what the hell is narrow band :D.

I like it even if it isn't the right colours :)

It's a bit grainy, but for an experiment ( with those filters) it is a great result!
Mario, you have inspired me to take some shots with the QHY5 of Saturn!!!

This is what it's all about Mario, having a bit of fun, experimenting, pushing the envelope.
Great image!

I'm not really equipped to comment - I'm not really sure what colour the thing is normally - mine come out yellow - and a little boy looked through my scope the other night at a school show and tell and said - "It's very tiny, and yellowy orange."
I said, "It looks tiny coz it's really far away and yes, it looks orangey doesn't it?"
I still like your pic though

Good experiment that turned out quite smick :)

Maybe a little soft on the focus, but I like it :)

You want to grab yourself a set of filters.

Thanks everyone! I'm very proud of this little image as I really didn't have that many pixels to work with. A lot of work went into it so it was a very, very pleasing result.

One thing I failed to point out was that, like my first effort, this image uses a 2x Barlow in the image train giving an effective focal ratio of f/14 to f/15. Another thing - I know this might sound odd - I've just noticed that I've managed to image Titan as well. Either that or I've got a smudge that appears in the same spot that Titan was in at that time!!

Very exciting to see Titan...:thumbsup:

Cheers,
Mario

Once again, well done Mario. I wouldn't worry too much about what is "right" and what isn't. This is the learning and experimenting phase - you never know what might turn up - some of the world's most intriguing discoveries and learnings have been done by not 'following the book'.

Cheers,
