Image of Jupiter and its fading GRS from 4:44 am this morning just before it went behind my neighbor’s tree. Clear sky, turbulence 6/10, no wind, temperature 70F. I used my usual setup: Celestron Nexstar 11, Televue 2X Barlow, Zwo ASI 224MC camera. Stacked and aligned with AutoStakkert; wavelet sharpened with Registax. Photoshop used to resample to 300 dpi, corrected color and brightness levels; soft light and high pass filter used to increase contrast a bit.

Jupiter from this morning June 12 at 4:35 am. Clear sky, 60 F, 10 mph wind, turbulence 6/10. The GRS and Ganymede visible near the west limb. My usual setup: Celestron Nexstar 11, 2X Televue Barlow, Zwo ASI 224MC camera. Aligned and stacked with AutoStakkert, wavelet sharpened with Registax 6, color balanced (had to cheat, underexposed), channels aligned, brightness level adjusted, and resampled to 300 dpi in Photoshop.

Being naturally impatient I couldn’t wait for Dec 21st when they are really close. Saturn and Jupiter tonight were separated by 1 deg 39 min 38 sec. Jupiter’s moon’s Calisto, Ganymede, Europa, and Io visible as well. Single exposure 1/40 sec at ISO 200 with Stellarvue 70 telescope and a Canon T3i. Image enlarged 4X; level adjusted slightly to bring out the moons; image drastically cropped vertically and about 30% horizontally. Obviously Jupiter’s over-exposed but I’d lose the moons otherwise. I’ll try for bands next time. Image below best viewed full size or more.

Image of Mars from yesterday, Nov 5 at 10:06 pm. Sky was mostly clear, some haze here and there. Temperature in the low 50s F. Seeing only fair may 5/10 — lots of motion and rapid blooming apparent. Captured with my usual setup, Celestron Nexstar 11, 2x Televue Barlow, and Zwo ASI 224MC camera. Forty seconds of video at 241 fps (ROI was 320x240 pixels), 9663 total frames. Aligned and stacked with AutoStakkert; Registax used to wavelet sharpen. G&B channels aligned to R with PS, converted to 300 dpi.
Mars CM was at 42.6 degrees. Apparent diameter is 19.12 arc sec, magnitude is -1.97.
