Re: white light comparison

Thanks Christian. When I imaged with the TEC140 in WL the image was crystal clear, when I added the Baader K line it was like a fog. With the CaK from Lunt it is crystal clear again. I can't remember whether this test was with or without a barlow. The PST is at prime focus and it works OK as a block...

Re: Solar Spectrum 0.5Å first light

Fabulous image Lou :hamster: :bow congratulations on the Solarspectrum. I would like to buy one but was told I would be waiting indefinitely and that the 0.3A is not available only the 0.5A. At least I can see now what a 0.5A one looks like in the flesh :)

Re: Attached Image Size on Posts

If you open Filip's animation in a new tab it looks like it is linked from astrobin.

Maybe you could PM him and ask? or ask on the thread.

Re: AR12822 extreme close-up 14/05/2021

That is a really stunning image Minh, you are really getting the best from your Quark :bow :hamster:

One thing to be careful is that there are no sharp edges on the Sun, it is all fluffy hydrogen plasma. So with sharpening, less is more :)

I love to hear that first light feeling :hamster: it gets better and better with every view :)

You were so brave to do that, I would have had a heart attack if you had dropped it. But, I know that you couldn't wait, neither could I.

Super images too :bow :hamster:

Re: Full Disk Mosaic in Ha with AR12822 and AR12823

Well, there is a simple answer to that but you have to look very closely. According to Zirin (Astrophysics of the Sun) p 174 in the blue wing the spicules are doubles called 'twinning'. In the red wing the spicules are singles. That is the only way I know that you can tell. I need to scan in the pho...

Looks like the Aurora alert was a bit late coming at 6pm, looks like the peak was earlier at around 12-3pm. Still no good as daylight hours, would have been good for the penguins in Antarctica though :)

Re: Full Disk Mosaic in Ha with AR12822 and AR12823

If you look closely you will see dark rosettes of mottles across the disc, they are flat and dark with white patches between. If on band the mottles would be 3D in structure and fluffy with no obvious white patches around, the surface would be more uniform and stuck up like grass. Very hard to descr...

Re: white light comparison

No good for what Mark? bad quality optics or just wide band? My Baader K line is permanently just out of focus, it works OK as a blocking filter for the PST at prime focus but when you use a 2x Barlow it is back to blurred. This one is 10A narrower and could be in focus and is much cheaper, that cou...
