Very nice pictures. They really motivate to try more and more.

How did you get the IMX178 working for h-alpha?

Your postings are a pure motivation boost. Thank you so much for sharing all your experiences!

Douglas,

Thank you for mentioning the transparency of your slit chrome layer increases at longer wavelengths. I built one into my UVEX4 (nicepeople approach) and wanted to use t more to UV and IR due to the mirror setup. Looks like I am going to concentrate more in the UV then...

I love this approach. I am getting curious trying more in this direction.

Ever tried an IMX462 sensor? This should be quite useful for that wavelength.

2.74um pixels... Interesting

Mark

I am a fan of small pixels. The seeing is more a problem, but the details are nice. When I am bored I am going to try a 1.2 x 1.2 um pixel camera, which was intended for a different application...

Finally I have had time to test the IMX545 (a2A4096-30umBAS - Basler ace 2) version from Basler. It is quite fast: 4096 px x 3000 px at 8 bit: approximately 25 fps 4096 px x 3000 px at 12 bit approximately 15 fps Basler.jpg I did nothing to this image. It is just stecked, everythign else is raw. (Bo...

I never tried it so far. What are it's advantages? Th eonly information I found so far is very very old...

I love it: the idea and the picture itself.

Maybe i should look for a 12VDC coffee maker...

Hi Rainer, it is the optical kit from Shelyak. We intended to sell it for interested customers. But because I left the shop suddenly my colleague pressed me the parcel with some kits into my hands. It is just a design for myself to prove if it is possible to motorize the "easy" setup. I us...

Yes, in both axis: collimator lens and focusing lens. Also teh grating is motorized

Because I cancelled my cooperation with the astronomy dealer (some Sol'Ex kits were laying around therefore), the weather is depressing and I always wanted to have a high resolution motorized SHG: I played around in Fusion360... SolKat.jpg I am printing it over the next days. It is like a mixture of...

I figured it out as well; Laura, thank you very much for the hint.

Genika works with Basler, not Touptek. Difficult then.

Firecapture... wow... Basler is supported, but does not run... seems to be a common problem when I look into the support forum.

Looks like we are stuck to the familiar sensors.

Robin decided against Basler with future version 4.1, therefore I have no hope that even Pylon 6.1.3 (yes, it works) will work in the future.

I never tried Genika Astro. Because it's licence is bounded to three cameras and I am testing a lot of cameras, it is not compatible to my requirements.

Okay, they do not work. Sharpcap does not support Basler anymore.....

Hi folks, I am taking a break from public and from solar astronomy. Working in this business has shown terrible things to me. It feels like people are creating their own reality and insult the others. Corporations are nothing worth. I am starting to lose my belief in myself and therefore need to get...

and printed:

This was the post I meant: https://solarchatforum.com/viewtopic.php?t=37829 Did you do some more modifications since that time? Aaaah, yes, There are the pics. No modification so far, but... I am currently adapting your slit into the solex, Douglas. Here the design of the new holder... Slit.jpg

Here one, maybe i did not get the focus...

I am not sure, if i ever posted pics. I am trying so many telescopes...

LEt me make some pictures as soon as the sun appears...

Ehm? Why is it a step forward? I am confused. I thought the french guys already did a lot before me?

The fluid to remove the coating is sodium hyperchloride soluted in water...

Yes, i did it by myself. I need to look waht kind of fluid i used.. it was easily available.

I will come back to you... let me hunt something to eat first.

The results are very nice with the decoated mirror. But.. (a big but) .. I never compared the results with a different setup with same seeing conditions. Maybe i put some aluminum foil back on the mirror to replace the missing coating. Then i just pull it off to compare it without. Sorry, just being...

I actually saw some sunshine today. :cool: BUT! It was 4C/40F and blowing a 20m/s {45mph] SE gale! :cry: I never saw that amazing AR3140 spot group. Not even once! :( ZWO and Touptek announced cameras with IMX990 or IMX991 sensors. They are claiming it would be possible to see through the clouds. F...

I decoated just the main mirror, this is enough. It works like a charm, at least for the SHG (spectroheliograph).

No.. not a laser.. we are close to an old airport. I am still trying to abuse the microwave oven. Until now I got at least some crispy doves... quite tasty.
