OK. It ain't great and I had to cheat a bit here and there, but the main thing that got me was how fast this thing is for its size. Still, low resolution data is better than no data at all. The times are my best approximation of the middle of the capture sequence. Capture was under control of Genika...

Very nice images

Did anyone catch the flare at 19:20 UTC today? I was running a camera, but not paying much attention to it. The seeing was downright horrible. Often the sunspot was just a blur on my screen. I did manage to get some captures throughout the event, though several frames lost detail to the intense brig...

What is the parameter you didn't find ?

Christian -

I couldn't find the setting for the SSM trigger threshold. It's a slider under Options | Other

Very nice image

Very nice animation. Is the Genika Astro better then the "FireCapture" software? I plan to buy the SSM monitor in the near feature and I don't know if I buy the Genika Astro software together. The Genika Astro software was developed by the maker of the SSM, so I wanted to use that. I have...

Lunt LST80Ha TeleVue 5x Powermate ZWO ASI174MM Still using SharpCap for the acquisition. I couldn't find the SSM threshold setting in Genika Astro. I know it's there. I have found it before, but it is in an obscure tab somewhere that I was simply unable to locate. I gave up and reverted to SharpCap....

Not the best, but you gotta start somewhere. It's good to know that I left room for improvement This is from 4 May, over a 4 1/2 hour period Lunt LST80Ha TeleVue 5x Powermate ZWO ASI174MM I was using SharpCap for acquisition for this one, but the next time I'll give it a go with Genika Astro, which ...

Not fantastic, but the best I have been able to get lately. Not too many peeks at the Sun around here

Thank you for your work

Awesome!

I have a Lunt 80, but things should work pretty much the same with the 50. On the Lunt scopes, the drawtube attached to the blocking filter is an important part of the focus mechanism. In order to more quickly set up my equipment, I made reference marks on my draw tube using a colored pencil. First ...

Bruce G

Thanks Alexandra. Today I wanted to show what happens with a camera that does have a gamma adjustment. The seeing conditions had deteriorated from yesterday and it was difficult to get a stable display that I could use to show small changes. In some cases I had to wait a significant time between sho...

Bruce G

Matry, Sorry it took so long to get back to this. I had to wait for the Sun in order to grab some screen shots. We're actually lucky. I haven't seen much of the Sun for weeks. The images below were made using SharpCap. Obviously, there will be differences with other acquisition programs, but the con...

Bruce G

The FLIR KB note makes some good points "Thus, using the minimal amount of gain that will still allow the A/D to saturate will help maximize the camera's dynamic range." This is the point that Valery was making. You want to use that whole histogram. BUT, once data values are clipped, they ...

Bruce G

Bruce, it is my understanding that for (our) solar imaging, when sharpening a stack, we need to remove the blurriness caused by 1) atmospheric turbulence (even though the stacker tries to choose the sharpest image fragments, it has to use some blurrier ones too), and 2) shift-and-add procedure (whi...

Bruce G

I struggle with deconvolution too, not because I don't understand what convolution is and does, but because we are handed a pile of deconvolution kernels with no guidance as to which sort of situations they were built for. Deconvolution is an inherently unstable process. It is a process of division....

Beautiful images Valery

I saw it as well when we had a tiny opening in the cloud deck. Quite bright, but still very small. Indeed it did remind me of the beginnings of that big loop, one that I was fortunate enough to see nearly the full development of. Perhaps Derek might catch something for us in the morning

Bruce G

Wow! Where did that AR come from?
I may have some clear sky, for the first time in ages, coming up in a couple of days. I hope to be able to catch this beauty
Nice work

Bruce G

Like I needed another way to spend my spare time!
Wow, there's a lot there

Bruce G

Awesome images.
Feeling rather humbled at the moment

Thank you Christian
I look forward to seeing further results

Bruce G

Bruce G

What SSMs were used in these tests, should someone want to replicate your results?

Bruce G

Very interesting results and very well presented.

What do you feel might explain that much difference? Dust in the air layer just above the ground or perhaps some other form of scattering phenomenon? Thermal currents close to the ground?

There are also those quick car jump power sources that hold enough juice to jump start a car. Way more than needed for a Quark, but if you're driving a tracking mount, a camera with cooler, a computer and perhaps a convenience item here or there, they'll cover all that and more. Small and light, the...

That is so great to see Pedro.
Not only are they great shots, but I just picked up a TEC APO140 myself and now I have an idea of what I might see (I haven't been able to set it up yet). You have me really anxious to use it now.

Bruce G

Yes the ASI120 is famous for Newton Rings, but a tilt adapter will do. You probably will need a lot of tilt. (At least I do have with mine, still surprised the complete field of view is still sharp) That took me a while to grasp as well, but think of it in photographic terms. What would the depth o...

Bruce G

Yes. If you are still at the point where you're not getting a usable image with what you already have, then you should hold off buying anything new until that is sorted out. I'm sure if we could all stand together in one spot with your gear we could have it solved in a few minutes but alas, we'll ha...

Bruce G

Sorry it took me so long to get to around to this. It has been a busy few weeks. If anyone has corrections or further information regarding this procedure, please post. I will incorporate what I can into the procedure. After that, the thread should be archived and these comments can be cut. Incident...

Bruce G

You might also tell us a little more about what you consider "improved results", as your imaging objectives should help you determine where your money is best spent. You had some imaging problems earlier and I don't know if you have resolved those or not. If not, a better camera isn't goin...

Bruce G

Paul - I tried a pass with the Global option and AS tolerated the bad frames, but the alignment problem persisted. Raf's examples with the birds provides another case where trying to describe to a piece of software just what constitutes a bad frame can be very problematic. It's often better to fall ...
