Jupiter GRS Europa Transit 8.9.10

[AztecastroMcJ]

yep it was 8.9.10 but not 11.12am lol

1st pic 1.05am 2.5xBarlow

2nd pic 1.35am 3xBarlow + Ext (cam pulled back)

craterlet, castrator, reg5, gimp, phixr

800-1000frames from 1200-1500

also got some using x4image mate and aslo using x3 Tal Barlow at normal distance

will post these up later as comparison of different image size captures

felt x4 was too much but x3 not enough so used camera not fully inserted into barlow which increased size a bit

more details see pics

also have noticed another artifact or cosmic ray on 1st pic under crop pick at edge of frame (bottom right)

looks like moon but nothing shud be there according to stellarium?

cool, what do you think of the Revelation 2.5 barlow ?

i`m hoping to pick one up today

[ezza123]

Nice pics James :-)

[beamish]

XLNT work James !

Your efforts keep us all honest !

[Clayton]

Interesting stuff James

No Moons in that spot anywhere near that date that I can see??

[beamish]

More debris falling in? Meteorite burning up? See S@N latest episode- looks very similar James

It's transiting nicely As for moons - it's possible to pick up Amalthea sometimes without special exposures. It orbits closer to Jupiter than Io. The other inner moons are much harder to get and need daily ephemerides from Horizons database to predict their positions.

You can put to Stellarium ssytem.ini file:

That new Barlow must be pretty good if it's picking up foreign bodies orbiting Jup!

[AztecastroMcJ]

cool, what do you think of the Revelation 2.5 barlow ?

i`m hoping to pick one up today

yeh 1st impressions very good

seems better quality than SW and Tal models

hard to tell if much difference visually but build quality is very good

[AztecastroMcJ]

thanks for comments guys

Clayton, Karlo, Rik, Stuart thanks for suggestings and interest of this mystery object

i have had look at the orig avi a couple of times and nothing is that noticeable

so this object seems to have only appeared after stacking and wavelets

doesn't look like hot pixel or cosmic ray, maybe another artifact ?

could this possible be reflected ghost image of Io maybe

is all i can think of, or internal reflection ?

it does look like moon with similar brightness

but as pic 2 shows Io was in different higher position at this time,

other main 2 moons were way off to left of pic

maybe smaller moon such as Amalthea but Doubtfull of this due to their app brightness and mag being very dim

i have uploaded the rotated and cropped pic

and zoom in 400% 800% 1600% sizes (nothing else adjusted)

opinions would be gratefully appreciated

James

[riklaunim]

Inner moons are in line with Jupiter equator. What you can done is process the image as follows:

- max wavelets (100 in each of them)

- push levels (PS/Gimp/whatever) to nearly max

This could reveal many dim objects on the image I use this for the mini moon hunting. What you got may be some ray/random noise, but it looks like bit elongated so it either lasted shortly or it something celestial. Hot pixel would leave a bouncy trail showing mount PE

[AztecastroMcJ]

ok looks like mystery object is camera artifact again after all

and i was just about to email NASA lol,

noticed sumthing about pic2 above

it too has mystery object only on left hand side of frame this time

suddenly realised on 1st capture camera was upside down while other captures weren't, so this must be sumthing to do with webcam

oh dear:iamwithstupid:

[AztecastroMcJ]

final post here,

promised barlow comparison pic @50% capture size

and pic2 above x3ext with different processing @100% capture size
