Download the latest version of Gimp (2.10) and also GMic for gimp that has fantastic filters including the FFT's
I already deleted the converted image on my system but there was a clear difference with the original.

Thanks Paul

Hi,

Here 3 images from yesterday May 15 with the QUARK through the window using a Takahashi FS-78. Still learning how to use it best.

Will put it onto my SKY 90mm as per some info I do not need an ERF for 90mm opening.

Also attached some images of the sky condition.

Looks like no more Newton rings. I shimmed with 0.1mm the camera onto the Quark but really do not know if that cured it or finding a better focused image.

Hi Mark,

Me too but here in Mexico City I do not have enough sky to test it over hours as the Quark has to cool down. I will need to do this at my Observatory where I have more time but at the moment no hardware to drive my scopes.

Perhaps also the conditions are not the best. Will have to pospone this testing to in a few weeks. I know they gave me a good one with low bandwidth.

I am not yet worried :lol:

Rainer

Rainer:
I think that the best way to start testing, is to focus it when cool, then put the heat on and keep looking for changes in contrast and refocus as it gets heated.
I believe that altitude (CDMX is 2250meters above mean sea level) also has an effect in getting the filter on band.
I have had some issues with etalons due to altitude and temperature changes.
Del Woods had to test my 2 Daystar filters at an altitude similar to México City, also David Lunt matched my 40mm etalons for the Egypt Venus transit, then had to do an etalon matching again when getting the filters back to México City.
Abrazo,
Eric.

Rainer,

I'm willing to bet that the window is what is causing the problems. Even if your Quark temp band was off, it would be different from this. To me it looks like what happens when I put a clear plastic bag in front of my objective. I'm betting your window is the problem.

By the way, I focus with it powered, when I test the tuning, I've yet to see it be any different cool versus hot. The difference is simply not chasing the seeing with focus, and figuring out which side (red vs blue) you need to be for maximum contrast. I use the surface for this test, not proms.

If you haven't already, point this scope through an open window without glass in front of it.

For tuning the Quark, you simply set it to 12 o'clock. Take a look. Then turn it all the way clockwise. Take a look. Then turn it all the way counter-clock wise. Take a look. You'll know which direction (towards red wing, or blue wing) you need to be to get best contrast. For me, in my conditions, that value was maximum counter-clockwise towards blue at 9 o'clock position. It doesn't take hours though, 5~7 minutes per value. Just knowing which direction to even test is the biggest time saver. Simply run a quick 200~300 frames once tuned at 12, 9 and 3. Compare the contrast in same conditions/focus. You'll know right away at least which side to start fine tuning things with. But regardless, to get good focus, get that glass out from in front your scope! :)

Very best,

Hi Eric and Marty,

" If you haven't already, point this scope through an open window without glass in front of it. "

You both made my Day

:seesaw :seesaw :seesaw :seesaw :seesaw

I would if I could. BTW I have shot through the window with a normal SM 40 and I see more detail in the SM 40 then in the QUARK

:shock: :shock: :shock:

Hi,

I am still working on my QUARK chromosphere and slowly but steadily getting better results.

I hope to get the Adapter for my ERF for the SKY 90 and then I will try with 12mm more aperture and see the difference.

Main Problem is really the bad seeing conditions I have had until yesterday. Yesterday was very good compared to all other days as I managed to get a much better focused Image. It is incredible how fine the focusing must be done. Without a fine focuser wheel on the focuser this would be nearly inpossible. Have not had any chance to add a motorized focuser.

Too many open construction sites :shock: especially testing the new mounts from iOptron CEM 120EC2. As any new Born they have some child diseases and I have to say the Tech Support from iOptron is top notch. They even answer Saturday and Sundays as well as on National Holidays ...

Will try to process some AVI's today.
regards Rainer
