Jupiter 20/21 June 19 Io trnasit and Red Spot

Recommended Posts

Hooray for the Atmospheric Dispersion Corrector!

Not the best Jupiters ever, but not too bad given it was at or below 14 degrees. ASI2120MC, 150PL and x3 barlow.

Great timing as I by setting up in an awkward spot to get it later than usual I caught the transit of Io and the Red Spot.

Beginners luck - first run seems to have the clearest Io,  just visible to the right of its shadow.

30% of 5,00 a hint of Io?

Great image's, well done. I've yet to get to image Jupiter this year, life has got in the way. Tonight hopefully.

Nice set of images, you can't beat a transit :) I was wondering, does the ADC have much effect? I guess what I'm asking is, have you done a before and after on the same night and noticed any difference?

A huge effect, you can see it on the screen, or using an eyepiece.

With the ADC set neutral the blue and red flare at top and bottom of the planet was about 1/5 of its diameter.

Here's some 2016 examples of how much an image can smear without an ADC, and why I got one.

Well done, great result considering the altitude. Clouded out down here again......

Very nice. Hope to take the next step from my  Canon to a more appropriate camera soon. Not looking forward to another learning session.

My timing here in Fla always seems to put the GRS out of my viewing times.

Don't rely on Stellarium, it's quite along way out at the moment, although the moons are accurate.

Nicely captured. Not easy at that height, even in good conditions, if such things exist down there!
