Jupiter From Melbourne

[Mickoid]

Took an opportunity in a short period of clear sky before clouds rolled in last night to take a shot of Jupiter. Seeing was fair but what worked out well was the GRS was in view at the same time.

1 minute video of around 3000 frames taken with a Canon 550d and processed in Registax. 200mm f5 Newtonian with 9mm eyepiece and a 2X barlow.

Nicely done :)
If you had have waited around the skies dos eventually clear up for the rest of the night :)

Tonight and tomorrow night should be great though it may get dewy

I guess it's a gamble with when to pull the pin on a session. I did notice that prior to the clouds coming over the seeing deteriorated which confirmed my decision to quit for the night. It was getting late and I do need my beauty sleep! Thanks for your comments and compliments guys, when living in Melbourne you never know what the weather will do next.:lol:

just had a quick peek a few minutes ago, the GRS is facing us but it was still too light to image. Lets hope conditions are good tonight

Hi Mickoid - great picture!

i take it you were using the camera in 720p mode to get the requisite 50 fps?

What ISO were you set to - as this is quite a short exposure time per frame?

cheers,

[Mickoid]

No, I shoot the planets with the 550d video crop mode which features on this model and the 60d, it crops the full HD to 640 x 480. So it uses a small portion of the 1080 x 1920 array, thus effectively enlarging the image. Great for getting focus and a fast frame rate. I shot Jupiter at 800iso because it is so bright. Seeing was only fair that night so I would imagine I could do better given good seeing conditions. Hope this answers your question.

Thanks answers both questions perfectly!

Will have to try crop mode via eosmovrec as I only have a 7d....

Cheers,

Wildly fluctuating atmospherics in melbourne last night, the North wind started up about 9pm making for really crappy viewing, I need to buy a few acres out in the bush......

I agree, set up for a good night imaging only to find Mars dancing and bouncing like a ping pong ball. Very bad, stayed out till after midnight hoping things might settle down but they didn't. Packed everything up and went to bed and thought-well that was a waste of time!
