Jupiter hand tracked dob

[john86]

Taken 9.05.17 @ 22.37. 3000 frames, 10" dobsonian scope x3 barlow on a ZWO ASI 120 mcs camera. GRS (great red spot) can been seen appearing from bottom left also GRS Jr mid bottom. The slight bump at the bottom right side is Jupiters moon ganymede. Processed in PIPP, AS!2 and RS6. Second photo taken same way and process just slightly earlier.

A fabulous example of what is possible with a dob mount, an excellent image.

Well done John, great image - you did very well keeping that on the chip by hand at that focal length 3000mm+

Great work there.... never a dull moment when hand tracking!

That's impressive! How hard was it to keep Jupiter on the chip whilst pressing buttons on your laptop? I was questioning the other day if it was worth trying this with my 6" Dob....now that question has been answered

Very cool 

Lots of details captured - nice snagging of Oval BA

Hello mate been using this method for around 3 years only just getting good at it though. I use sharpcap to capture the avi and once I have sorted the histogram out on unrecorded test runs I set it to record for 2 mins from pressing start, I basically don't touch the laptop while recording. I find the best way is to be sat down elbow on knee to steady my arm while holding the handle to track, I have got quite good at it lol

Thanks John, you're obviously a tenacious man, I did think it would be very hard at such a focal length with a small chip! Well done for sticking at it, I'm not sure I'd have the patience to get good at hand tracking, so might try and get my hands on a 150p or little Mak for my EQ3 with motors. I've not done much planetary or DSO imaging for a couple of years now, but my last few Jupiter and Moon observing sessions I've had an anchoring to image again. 

Keep up the good work, you should call yourself steady hands John
