Sun FD in H-Alpha and CaK 13th of September 2021
Dear friends,
Today's Sun was not at all as spectacular as yesterday, but still some nice prominences and of course the departing AR2866, 2868 and 2869.
The best part was not having to dodge rain (like the day before) and the pleasure of using the new upgraded focuser for the first time. Over the weekend I replaced the stock helical focuser (which was absolutely terrible) with a MoonLite focuser. The MoonLite focuser came with an used Celestron 9.25" I bought a few years back and I just had to order the correct flange adapter to attach it to the Coronado scope. Removing the old focuser though was everything, but simple. I spent a good hour struggling trying all the tricks in the book (heating with hairdryer, light tapping with wood and a filter wrench) before I was finally able to get it loose. It appears to have been secured with red loctite.
Anyway, here is a picture of the Coronado fully dismantled.
And this from todays session using the new focuser. An absolute delight to focus!
Also seen in this picture is the 3D printed 50mm aperture mask with the a step-up outer diameter to fit the FlatCap from DayStar and the 3D printer "solar shade" for the camera :-)
The C9.25", which I use for solar WL imaging, is now without a fine-focuser until I receive a PrimaLuce Esatto 2" robotic focuser that I have on order.
OK, enough hardware talk. Here are todays imaging results.

Really excellent disks Arne! I like the pictures of the scope and particularly like that rather cunning camera shade you have produced.

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Excellent captures Arne and of course a decent focuser can make all the difference when a previous one is just simply not up to the job...
Good to see that you are using the best tripod available as the Berlebach Report 7003 from the manufacturer who has been around for yonks and knows exactly how to make the best... I have another one of their designs as well...
Thanks for sharing your efforts and well done on the change

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Very nice images Arne and I love the setup. I have thought about getting a Moonlite focuser for my Orion70.
Is your Coronado a SolarMax or early SolarMax II? I notice it has an anodized tube.

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Arne, very beautiful FDs. It even seems to me that it was filmed through DS. The monochrome version in Ha is my favorite. I also really liked the camera screen, it even seems to me that it works like a radiator.

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Thank you very much everyone for all your kind comments!
Mark: Trying hard to come up with things that I can 3-D print :-)
Terry: Berlebach tripods are great. The build quality is excellent build quality and they are light and sturdy. Wood also have a nice natural vibration dampening. Plus I think they look cool! I have 4 or 5 different Berlebach tripods (from the small table-top model to a larger model for mounting my old Vixen GP-DX mount).
James: I've got a SolarMax 60, SolarMax 60 II and a SolarMax 90. I tried to order a complete MoonLite focuser for my 90 as well, but was informed that they were phasing out all manual versions and that they didn't have the required model for this scope left.
Ivan: I have tried DS this front filter with my SolarMax 60 II, but haven't mastered it yet. I'm getting far better imaging using it SS on the SolarMax 60. I haven't had the chance to measure the camera temp with and without the shade yet, but I like to think it's a good thing to keep it in the shade :-)
Best regards,
Arne

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Thanks Arne for the Berlebach comments which are the benefits of laying-out for the best.
Mine is the large one for either of my two Vixen GP-DX mounts and expected to see much more use in the coming months.
It is the "PLANET" Tripod Including Tray 37 cm + Spread Stopper and certainly is well nice and easy to use.
Mark, If I was finking about departing my Barlebach, you would have the first discounted option, but if you haven't already found the U.K. supplier, then that is :- Astrograph Ltd.

Love the full disc images, especially the h-alpha. Great job bringing out the prominences! What processing technique to you use to do so?

Re: Sun FD in H-Alpha and CaK 13th of September 2021
Thank you very much for your kind words.
I'm sure there are both better and more efficient ways to do this, but my current flow for the H-Alpha 60mm FD images are as follows:
1) Single recording using FireCapture
-Gain = 30
-FPS = 60
-30 sec recording
-Gamma = Off
-Shutter around 3ms (max value of around 230 in the histogram)
2) Stacking in AutoStakkert!3
-Stack of best 60%
-Multiscale and AP size of 56
2) Sharpening in ImPPG
-Lucy-Richardson
-Sigma 1.1
-Iterations 60
-Unsharp
-Sigma 1,2
-Amount 3,0
3) Rotate/Crop in ACDSEE
4) Contrast adjustments in PhotoShop
-Levels
-Auto
-Black clip: 0
-White clip: 0
-Shadow/Higlights
-Shadow parameters
-Amount: 100%
-Tone Width: 30%
-Radius: 10
-Levels
-Gamma: 0,7
5) Colorization in PhotoShop
-Convert Mode
-To RGB Mode
-Levels
-Red
-Gamma 1,7
-Green
-Gamma 0,6
-Blue
-Gamma 0,2
-Color Balance
-Shadow levels: 20, 0 ,0
-Midtone levels: 20, 0, 0
-Highlight levels: 0, 0 10
-With preserve luminosity
-Hue/Saturation
-Hue 1
-Saturation - 26
6) Resize and convert to web in ACDSEE
I have slightly different sharpening settings as XML files for ImPPG and recorded actions in PhotoShop that I use for different camera/filter/scope combinations. Thus, the settings above will probably not work directly for your images, but should hopefully give you an overview of my workflow and some starting points.
