Hi everyone,

 

Following my previous imaging on the 19th which was more a test to renew with planetary imaging, here is some more interesting imaging of the Europa Transit over Jupiter.

 

It was the first time I tried the collimation with MetaGuide. At first, it wouldn't select Vega in the frame.. then after adjusting the camera parameters, I could see the star hot spot and "dancing halo" around. Seeing was probably not great as I had to increase the stacking to 5s and even 7.5s to get a somewhat stable airy disk. The scope was close to collimation but I managed to improve it further. Even though, the red dot was moving around:

FC Settings on ZWO 462MC:

- exposure: 5.8ms

- gain: 302

- each frame: 60s video at 172 fps 

 

1 image out of 323 captured:

Final planetary rotation (AS3!, Registax, PS):

I could probably improve the processing of the video as I was using the same wavelets from start to finish. When the seeing was improving, I feel like I was close to the max resolution of the C8 EdgeHD. Let me know what you think !

I finally got the time to try Winjupos and indeed it does improve quite a lot the details. I stacked about 30 images with Winjupos before applying Registax. I then double the resolution through Topaz AI gigal pixel, sharpen it a little as well, and finished with a light processing in photoshop:

 

 

I am pretty happy of the result for a C8 edgehd. I didn't mask Europa and replace it by the original image yet as I was wondering if when using Winjupos, it could also align Europa ? I wasn't expecting that trail.

Yes, that's quite a nice result! WinJUPOS can derotate moons, in the derotation window hit "Options" and check "Correction of the planetary moons and their shadows".

Thanks Winteria, I will definitely test that option !
