After 30 minutes of sketching, I also run out of patience while trying to make a dark and uniform background around Saturn just with one pencil (B)." Graphite works well but it is messy and takes just as long.

I meant to say charcoal works well but it is messy and takes as long as graphite.

Colors were nice again tonight but the seeing was much worse. Despite of this, there were still some interesting details visible

Tonight, I took my largest refractor AS110 (I do not observe with it too much from backyard, the lens is quite old, plus the OTA is at the edge of limit of my light mount). GRS was just setting down, seeing was bad, still many details were visible. I could clearly see larger resolving power with respect to 82mm. All the details that are at the limit of detectability in 82mm were much more defined. I was also showing Jupiter (and Saturn) to my daughters. The two oldest were saying that they could clearly see GRS (and belts).

Tonight, the conditions were not so great. I correctly guessed that I was observing in SEB at western edge a region just following GRS. I also more or less guessed that tiny darkening in NTB was a moon shadow (of Europa as I discovered later on at home)

And one more from tonight. This time with GRS and again moon shadow. I was also trying my new 3mm eyepiece. To my surprise, it was useful as it revealed few more details than power of 114x. For example it was showing that SEB preceding GRS was curled to the equatorial while the following part was curled towards the south.

Alexander, I am speechless with the work you do with a modest aperture. Especially when they look similar to images in a larger aperture. Very nice. Telescope.gif

Probably last two sketches in this apparition. Weather forecast is quite bad for next couple of days and already in the last two days I hardly found time before putting the kids into their bads (after it is too late). Luckily, setting up 60mm refractor does not take that much of time

On night of September 3rd, I had at the beginning a feeling that GRS was just setting down at the western edge. However it was not the case, but there was definitely some darkening (I have not checked the images yet to figure out what I saw). Yesterday, there was GRS in this position. Color was quite striking, it was quite bright/light orange in contrast to much darker tone that I remember from previous observations. May be this was just thanks to very good atmospheric transparency.

Still managed one more Jupiter. This time through borrowed Newton 150/1200. Seeing was bad, still it was clear that the telescope was providing better resolution than my 82mm refractor. Take the details with reserve. Due to bad seeing I was not able to confirm many recorded features

One more under less than perfect conditions. Still I was able to glimpse oval BA (but no shade of Io, although I was looking for it)
