Comparison ASI224MC Vs. ASI290MM

Good seeing conditions, average/poor transparency. For ASI224MC = C14 + TV 2x (@ f/30) + Luminance For ASI90MM = C14 + TV 2x (@ f/22) + RGB set Same total combined videos duration (5 minutes), Firecapture, AS!3, WinJupos, PixInsight and PS used to process the images Taken from my 12 story apartment terrace in Singapore

Full rotation of Jupiter, April 30 / May 1st 2017

This is Jupiter's full rotation (lasting about 10 hours) taken in two nights between Aril and May 2017. In total over 100 videos of 90 seconds ended up in this job, about half a million single frames stacked with AS! 3 and then derotated with Winjupos to create a final set of 34 stacks merged in a map and then reconverted to create the rotation video. the full processing took a lot of time and was not trivial, also because planet morphology changes significantly from just one day to the other.

Jupiter full surface map, April 30 - May 1, 2017

This map of the full surface of Jupiter was realized with images taken in two nights between Aril and May 2017.

Jupiter May 1, 2017 in Luminance and CH4 filters

Comparison of different aspects of Jupiter when imaged in visible light (luminance) and CH4 (Methane) light. The two images were taken few minutes apart, enough to show the fast planet rotation. Despite the telescope relatively little aperture to image in narrowband filters (CH4) I am surprised by the result. Good seeing condition. At the moment of the imaging (May 1st 2017) Jupiter diameter was 43.4". Luminance 3x90" videos (about 12000 frames stacked), CH4 7x90" videos (about 2,600 frames stacked). Sum and derotation using AS!3 and WinJupos. Wavelet and RL deconvolution using Registax 6 and Astra Image. C9.25 + TV Powermate 2.5x - ZWO ASI224MC & L and CH4 filters - iOptron CEM60 - Singapore
