    GRS Transit on Jupiter, crossing the meridian at 4.18am with Jupiter at just over 21 degrees altitude. GRS starts to come onto the disk at around 2.10am, disappearing at around 6.15am. A couple more events too, an Io Shadow Transit starting at 4.22am and an occultation or Ganymede at 4.29am. Full timings in the attachment. Best time to view is probably 5.18am with both shadow and GRS well positioned.

    As per Chris's post, GRS and a shadow transit of Io are visible tomorrow morning, weather permitting of course! Io Shadow Transit starts at 2:28am, finishing at 4:39am GRS Transits at 3:32am, and Jupiter itself transits the meridian at 4:53am Between 3:30 and 4am could be an optimum time, Jupiter at around 19 degrees and above, not far off its highest at 21 degrees.
  3. 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
  4. I am new to telescope .. i have Nexstar 5se .. moon seen clearly .. while watching mars , there is black shadow (circle ) in middle of mars .. same as seen in star .. it goes bigger when increase focus
  5. Hi everyone, I seem to have an issue with my NS camera that I can't figure out. Whenever I take a picture, every bright object in it, especially stars, have a black shadow on the right part of the image. I have disregarded the effect coming from the telescope or reflections from outside, because the shadow always appears on the right, regardless the angle of the camera with respect to the telescope. The effect is very apparent when I'm focusing. I have attached several pictures to see if someone can give me a hint: - ...004: focusing street lights - ...006 Calibration (Dark) - ...008 Calibration (Bias) - ...010 Calibration (Flat): pointing to a street light and trees - ...013 Focusing a star - ...019 Picture of street lights - ...003 Focusing a bright star - ...5420 Picture of a star field
  6. Seeing was mostly poor, but I am quite happy with how it came out
  7. Quick and dirty animation from last night. The least best images in the animation are due to tree branches partially obscuring Jupiter during the sequence. Seeing was pretty poor (Antoniadi IV,V) - making focussing difficult C11 on EQ8, DFK21AU camera, 25fps, x2.5 barlow, efl ~ 7m betwee 21:04 &21:55 UT
  8. Hi, I know it is way off some of the excellent images taken by other members of this forum but I am so chuffed with this image I am afraid that I wanted to show off! It was taken though my C8 without a diagonal. The camera used was an unmodded Philips SPC900NC - no barlow lens. 1000 frames were taken at 10 frames per second and the best 250 stacked in Registax 6. I then did a bit of post production in Photoshop 7.0.1 and cropped the image to enlarge the planet in the frame. The shadow is of the moon Io which is, I believe, right next to the GRS. Thanks for looking. Edit: Oops, sorry forgot to say, taken on 01 November at 21:19 UT with quite poor seeing. CG5 Advanced GT mount used.
  9. Not as good a Jupiter as some high-end set ups are already getting but I did catch some transit action this morning.
