Finally... my first image.

After patiently working through registax for the first time today, I finally have my first processed image to post. Any suggestions on how it could be processed better, I'm all ears.

Nice close up Bones, not sure but try a little more wavelet sharpening may get a bit more detail. If not then would be a bit more focus.

Interesting to know what camera and scope you used and whether it is tracking or across field of view capture.

Thanks Malcolm. I'll sus out the wavelet features a bit more. I used a CPC11 with the DMK21, no barlow.

I was struggling with the focus a bit on the night. I didn't use the filter wheel because I was just starting out with the camera and being the moon, didn't expect any colour so I went for the straight black and white through the mono.

It's a good start

These are the wavelet settings that I last used on a moon image.
Not every image is the same though, I adjust to suit.
Thought it might help a little.

Wavlets will depend on how many frames you stack. This is what I found.

Initiall use the default setting and adjust the top slider first then work your way down. In some cases you may only need a couple of sliders.

Later you can experiment with the setting above the slider to extract some finer detail.

Great first up image!
I reckon you should keep going with prime focus imaging - I always jumped in with barlows and Powermates and you need great conditions to get good stuff - prime focus is a touch more forgiving and pleasurable.
Muck around with the slides but as mentioned you often only need to tweak slider one and two.
Really great image number one!

Thanks for the feedback thus far. Here it is again reprocessed a bit more with the wavelets and cropped in similar way.

Nice work Bones.

As you can see in your 2nd go, you have introduced what looks like noise.

That is from being heavy handed on the wavelettes.

Funny how we all have different ways of doing things.
I have always found that Lunar/Planetary image stacks in Registax only need the bottom 3 sliders adjusted. and not too much.

DSO's a tad on the top one then play with the bottom 3.
I always leave the other sliders alone.
Too much introduces artifacts and noise.

It's really just trial and error. An image out of a dslr will be different to that from a webcam to that of a ccd.
As mentioned, the number of images stacked is another variable to take into account. Then personal taste comes into it too, or whether you are processing to accentuate different features.
What ever you're doing though, enjoy the learning curve. This is what makes Astronomy so much fun.

Great improvement all learning experience as we have all had to do when starting out. As Ken mentioned little over processed but great to get an idea how the sliders work.

The more frames processed can have 2 affects, less noise as experienced but on the off hand processing too many frame can introduce some bad frames which has a negative affect.

Quick Q! how many frames did you capture and how many did you process??

Keep it up doin' great.

Yeah, as jj says, just fiddle with the sliders and other settings.
You may find a setting that you like that we haven't even tried yet.

Here are the settings I used the most: Lunar/Planetary and DSO

LOL I go hard on my wavelets compared to you Ken.
I save a scheme for each object, apply it to the image and work from there.
There has been times when I have to back right off from where it started.

Congrats on your first image Tony, well done.
There's no stopping you now, this stuff is addictive.

Good advice so far.
The second image is overdone, I prefer the first.
Just go easy on the settings and experiment.
You'll soon get a feel of the sliders.

Hope to see you soon at the pony club.

Keep it up doin' great.
I captured 3904 frames at a rate of 30 frames per second. When it came to processing, I had it set for the "lowest quality 95%" and aligned on 14 alignment points at I think best 30 each ??? When I captured last Friday, it was a bit windy down below but looking at the jetstream maps it was a lot more stable above.
