After one or two failled attempts I finally managed to image Jupiter plus its Great Red Spot, Ganymede and its shadow. Taken using an unmodded Toucam and an IR blocking filter attatched to a 200 mm Skywatcher Explorer with a 3x barlow and 1227 images stacked. I had the added problem of Jupiter going behind the trees during imaging, where I am there's trees everywhere and I only had a small area to place my telescope, I just can't avoid them so I was having to deal with an image that was darkening then brightening for most of the time, but one good thing about winter is all the leaves have fallen so I can see through the trees. Also I couldn't see the northern sky so it was just a case of pointing the mount what I reckoned was north, so constantly having to press the direction button to keep the image in the centre of the field
Just an example of a typical quick observing session for me, trying to fit it in around 'life'! I have a baby due in a couple of weeks so we are manically preparing the house and nursery for the arrival. I set the TV76 and PST up in the garden early on Sunday morning, and during rests from painting skirting boards had some lovely white light and Ha views. My mini giro rig is working very well now, more compact with the shorter CW bar and L bracket. During breaks from assembling a flat pack IKEA wardrobe (AAAARRRRGGGGGHHHH), I realised there was a double shadow transit on Jupiter last night so thought I would chance my arm at a little evening session too. I popped the PST and Herschel wedge away, put the longer CW bar on and away we went. It's amazing the detail visible with such a small scope. Earlier on GRS was clearly visible, with nice detail around where it nestles into the belt, whilst the Ganymede shadow transit was stunningly clear, really jet black. Nice details in the other belt too in moments of good seeing. I tried a variety of EPs, and settled in the 3.7 Ethos earlier on (x137) when the seeing was better. Later on the 4 mm radian gave sharper views at x120. I watched the double shadow transit at its mid point, Io's shadow smaller and less obvious but still very clear. That's a first for me I think. My last view was as Ganymede's shadow was about to exit the disk, but the seeing had dropped off by then. Packed away very quickly and off to bed. It's great to be able to view these events with minimum hassle. I know the detail is not what you would get in a larger scope, but if the choice is that or nothing, I'll take the small scope option every time. Cheers, Stu
Hi All, After high cloud passed through the seeing was fairly respectable. A lovely view of Jupiter, with the Great Red Spot on disc. Europa was just off planet with its shadow transiting near the GRS. Best regards, Pete Lawrence
