Re: Convolution / Wavelets

Not exactly a simplified explanation, nor helped by somewhat 'poor' subtitling!

Gives me a clue of sorts, especially as it is related to astronomy images....

Re: Convolution / Wavelets

Thanks GA.

So the process is effectively making an attempt to remove the earth's atmosphere (the blur) from the telescope image?

It's the how that is intriguing....

Re: Convolution / Wavelets

None in particular Mark.

Just interested in what happens at the level of the pixels to understand the underlying mechanics to teach the final images.

I still use imPPG for preference, with recent dabbles in Astrosurface - though that latter one is proving less easy to use at the moment.

Convolution / Wavelets

Can anyone recommend a source (simple explanation) for what the various convolution and wavelet processes do when they affect our astronomy images. I found a stacking tutorial that helped my understanding of what's really happening, just need a similar guide to the next stage in the sequence. Cheers...

Re: Guidance please: blocking filter ls60

Hi Marty, Thanks. I generally have little 'problem', it was just yesterday the focus on the sun was unusually soft and, as I'm getting back into the swing of things again after the scope returned from service, I 'just' wondered if the blocking filter needed to be a specific distance in/out. I guess ...

Re: Guidance please: blocking filter ls60

Sorry Mark, I should have said. Camera. Basically is there a definite sweet spot beyond the suggestion by Lunt which is 1-2 inches. I know if it's too far out I get uneven illumination across the view.

Guidance please: blocking filter ls60

Lunt ls60 blocking filter

Is there a way to work out the sweet spot on how far in/out for the blocking filter? I guess most of my issues this morning were with poor seeing. But it would be useful to know if there's something more 'expert' than about 1-2 inches out!

Rings are not an issue I have (fingers crossed) - have you tried a de-focus flat? Otherwise you may need a tilter?

Re: Lunt LS60 & USB Controller

leaks at the controller are extremely rare. Your case was the first time that something like this happened twice to a customer. If there is a leak, it can unfortunately only be repaired by our technicians. Looking forward to seeing the toys back home - hopefully the clouds will have cleared by then!

Aurora this morning....

Looking forward to the next season when I'll be replacing the 150 degree lens with a 63 degree - hopefully fewer light sources to affect the camera software - hopefully.

Wonderful. I envy you your patience to be able to do something like this. :bow

I assume you take the pad to the eyepiece, and not run between the table and pad trying to remember positions :geek: :mrgreen:
