Sunday 2021 December 12 Seeing was NOT DISGUSTING this evening.. merely poor! See these three here: https://starlightcascade.ca/blog/2021/12/jupiter-2021dec12/ The following three images are the best 5%, 10% and 25% of 1340 frames with autostakkert3! in a 30 second run. This really highlights the need for more frames, more signal to noise. In the best 5% may look a little sharper than the 10% and 25% but the noise mottling on the surface is very noticable! Jupiter best 5% of 1340 Jupiter best 10% of 1340 Jupiter best 25% of 1340 And below is the best 25% of a 180 second run with over 8300 frames.

Saturday 2021 December 4th evening seeing = 1 = DISGUSTING Initial image full res wide view overexposed to confirm moon orientation no barlow. Ganymede further out on left, Europa closer in on right then to x1.5 barlow for this image and a smaller Region Of Interest (ROI). Still looking for a powered USB hub to help with the USB powered motorized remote focuser... arriving any day now. Still may need a tad bit of tiny optics collimation.

From the late afternoon.early evening of 2021 December 03. Seeing again was 1=DISGUSTING. The colour debayer issue has been solved thanks to the ability to compare and contrast two cameras in the same session. Thanks Mark D.! The North Equatorial Belt show up nicely, and is darker and larger than the South Equatorial Belt. In other news the Great Red Spot is shoing up in the lower left FireCapture v2.6 Settings ------------------------------------ Camera=ZWO ASI290MC Filter=L Profile=Jupiter Diameter=37.99" Magnitude=-2.28 CMI=262.0° CMII=341.7° CMIII=193.3° (during mid of capture) FocalLength=1650mm Resolution=0.37" Filename=2021-12-03-2227_3-L-Jup_ZWO ASI290MC_Exposure=3.0ms.ser Date=031221 Start=222551.492 Mid=222721.496 End=222851.500 Start(UT)=222551.492 Mid(UT)=222721.496 End(UT)=222851.500 Duration=180.008s Date_format=ddMMyy Time_format=HHmmss LT=UT Frames captured=12916 File type=SER Binning=no ROI=664x608 ROI(Offset)=656x232 FPS (avg.)=71 Shutter=3.045ms Gain=297 (49%) WRed=50 (off) WBlue=90 (off) Brightness=1 (off) AutoExposure=off HighSpeed=off Gamma=50 SoftwareGain=10 (off) USBTraffic=68 (off) AutoHisto=75 (off) AutoGain=off FPS=100 (off) Histogramm(min)=0 Histogramm(max)=193 Histogramm=75% Noise(avg.deviation)=n/a Limit=180 Seconds Sensor temperature=5.8°C

2021 November 23 More commissioning attempts at solving the bad colour. This is the results of processing 39 runs (more actually, some were very bad and not included) through PIPP (.ser to .avi and centered and cropped), autostakkert!3 and using the best 25% of those images, then finally through registax wavelet processing for sharpening. This was using two cameras again, the ZWO ASI 224MC and 290MC, in an attempt to nail down the root cause. My initial suspicion was the 290MC camera, but the borrowed 224 MC camera showed the same issues. So it was not the camera… Seeing was Kevin’s scale of 1=DISGUSTING. A variety of barlows was also used. The issue appears to be in the whole debayering settings in firecapture, the cameras and how they get interpreted. Thanks to Mark D. whose help was instrumental in troubleshooting, with a second camera to isolate variables and simplify the system for testing one at a time. We may need to buy a 2nd camera just to have on hand when more testing is needed! For the last image: Profile=Jupiter Diameter=39.13" Magnitude=-2.34 Altitude=22.58° Airmass=2.60 CMI=222.8° CMII=17.9° CMIII=226.9° (during mid of capture) FocalLength=6600mm (F/64)


Monday 2021 Nov 22 This is one of the last image of the night’s run… still needs collimating.. and the colour issue still needed to be resolved. This was with our ZWO ASI290MC camera and a borrowed ZWO ASI224MC camera: Profile=Jupiter Diameter=39.25″ Magnitude=-2.35 Altitude=29.35° Airmass=2.04 CMI=19.4° CMII=182.6° CMIII=31.3° (during mid of capture)

Friday 2021 November 19 evening After doing the barlow test, I moved ahead to try Jupiter out again… with the max x3 barlow (which turned out to have dust spots, so it too is now inside for cleaning). So this is quite impressive in target size… 1800mm focal length x3 = 5400mm. Somewhere around 600 pixels in diameter (after a x1.5 drizzle pixel increase by interpolation with autostakkert!3) Focusing is still difficult and could be better. this is a 180 second imaging run at 30ms frames (about 33fps) with the new firecapture beta software, no debayer in firecapture, autostakkert!3 that does the debayering for colour, the best 25% of 6k frames and wavelet processed in registax.


2021 October 22 evening This was a test using the an older ZWO ASI 120MM camera and both authstakkert!2 and autostakkert!3 The results were comparable with the newer ASI 290MC camera and both versions of autostakkert. The focus is not sharp and all images were about the same.


2021 October 01 This was the last images of the Jupiter imaging test from Friday night, after 2000 EDT and into the next day UTC. So.. the details… The ZWO ASI290MC camera has been giving unsatisfactory images of late so I borrowed an ASI120MM to try out and try to narrow down what may be happening. So with 0 barlows on the native 1800mm focal length VC200L OTA on a Skywatcher AZ-EQ6GT mount, I started with 15 minutes of trying to find Jupiter… before taking the lens cap off. Note to self.. take off the lens cap. OK.. found Jupiter, exposed using firecapture so the histograms come up at 80-85% with default gain and gamma. This turned out to be a 4ms exposure. I normally take a 30 sec firecapture unaligned followed by a 30 second firecapture aligned run to have a baseline for comparison of the seeing that evening. Last night was average seeing and average transparency… until the clouds came along. After that a 180sec exposure (old rule of thumb that I used on an older telescope.. the max exposure before Jupiters rotation moved a feature from one pixel to the next.. you don’t want that), I then repeated it all with a x1.5 barlow (there was some dust on it!) at 10ms and then with a x2 barlow (dust on it as well) for a 20ms exposure. During the very last run (the image above), terrestrial clouds were moving across the face of Jupiter, causing it to totally disappear at times from the display. I kept a small Region of Interest of about 700×700 pixels, to increase the framerate because of the smaller USB bandwidth needed.


2021 September 18 Pretty poor out last night for planetary… almost full moon, very close to Jupiter. Seeing poor, transparency poor. This image was the best, the last of the evening. 180 second run, 22ms exposure, about 8200 frames in all, used the best 25% of them with Autostakkert! v3


2021 September 17 evening Io on the left, Europa on the right. Some glare/focusing artefacts on top and to the right of Jupiter and maybe a ring around it as well. Thinking that the collimation is not quite right. no barlow, 1800mm FL, 4ms expsoures, 11 day old waxing gibbous moon


2021 September 03 One of the better attempts in some time. Also captured the moons Io and Europa in the field of view (right side).


2021 August 15 More commissioning attempts at solving the bad colour, poor focus and strange software with debayering.


2021 August 02 evening Trying out the new mount and scope with a barlow lens x2 Focus is poor, optical path seems upside down.

2021 July 24 This is the first light image, a 30 second run with Firecapture (no autoalign) on the mount which has not yet been polar aligned or three star aligned, just roughly polar aligned by eye in the daytime and manually driven to Jupiter. It had 2975 frames and stacked with Autostakkert! 3.1.4 and the best 5% of the frames were used. (about 150). Regixtax wavelet processing was next where the rgb colour was balanced as well.
