Re: Quarks: Chromosphere vs Prominence

This is only speculation, but i believe the prominence version has a higher degree of tuning blue and red wing to see the doppler shifted prominence without losing it entirely from the image. The chromosphere version is basically on off tuning.

Re: PST stage 4. The X-truder

Thought i would put this here. . This is an example of what I see before processing. IF you look closely and manage to focus on certain areas there are two filaments visible

Re: Jun 26, T250, Telecentric x5, CaK

here is a sample of what I am seeing on my screen in raw format unprocessed. I am using a pst objective as a refocus lens on +5000mm.

Well i've just tried stacking my pst etalon on the Na Quark and made no improvement to anything with a dimmer image.
Did you keep the collimator attached?

Re: Jun 26, T250, Telecentric x5, CaK

I was only asking because how dark the image was. I am trying to get a similar magnification on my xtruder telescope mod. I figured a 250mm mirror would provide a super exposure :). And your raw frame is a better example. Processing cak images is a learning experience for sure, so much more sensitiv...

Any chance you can post a raw unprocessed animation so we can get an idea of what the camera sees in real time?

Re: NEW direction in the solar narrowband imaging.

I've seen the etalon bands all the way down to the UV, but never paid attention to the NIR, I expect to see them all the way. How close is one band to the required CWL I think will be the issue. (OK, found an old spectrum of a PST etalon - low resolution and not focused for the NIR but the waveleng...

Re: NEW direction in the solar narrowband imaging.

If anyonehas a modifed pst, just remove the blocking filter and put an 850fs10 filter in front of the collimator. If you get an image it broadcasts the 850 specrtum. Simple test, itll cost like 100$ but will be worth it if it works for getting the image we are lookin for.

Re: Reflected sunlight fluorescence

It is a multiband fluorescence filter that does ir/uv and various other wavelengths, i just have to tilt it to find the good stuff :roll:

I enjoy looking at the sun reflecting off flowers to see like a bee. These are Tiger Lilly , doing something you may never see otherwise.

Re: PST stage 4. The X-truder

Got my first light solar images today! it will never be "perfect" because nothing ever is, but now you see that it works. THere is great hope. Keep in mind sunlight is being pumped into two pst objectives from the primary 100mm F/5.5 objective Going to change the lens positions a couple more times ...

Re: iPhone 6 no colour

you need a rig to hold the camera onto an eyepiece. that should be the first thing you try. Holding the phone there with your hand is never going to work :)

You can easily make one with cardboard and tape, or can get the pro made one off ebay

Re: NEW direction in the solar narrowband imaging.

I think it may be entirely possible that the PST etalon and maybe all hydrogen alpha etalons broadcast this wavelength to an extent. It might be in our best interest to get the total transmission of a standard pst etalon. I understand the coating maybe an issue, but if the etalon is already transmit...

christian viladrich has a model of something here with the coronado etalon, i do not know if it is real or just a theoretical idea

Re: NEW direction in the solar narrowband imaging.

Okay, i found it valery! This may confirm that the ir caii kline is indeed in the middle chromosphere like h-alpha. Howvere the ibis filter method is still not attainable by amateurs unfortunately. 1anstrom maybe enough to resolve something new and definitely a good place to start. http://www.arcetr...

Re: NEW direction in the solar narrowband imaging.

We need to get ken and spectral joe to design a grating system using common parts that take high magnification, nonfull disk image scans. Then you will get fibrils!

Re: NEW direction in the solar narrowband imaging.

The fibrils you want are also at 393.37nm and 396.9nm , They can only be seperated from the surroundings by a grating. Or maybe a quadruple half angstrom system.

Re: NEW direction in the solar narrowband imaging.

I firmly believe The only reason we are seeing these fibrils in the ibis image is because its about .05 angstroms from a grating. They are using a standard bandpass filter with 5 angstrom at 30% transmission to send a very narrow image to a reflection grating Which is funneled into two slits. Even w...
