Attached are two images from yesterday evening. Seeing was 8/10 and trans. 4/5. The 25.4 cm f/12 refl.,2x barlow,ToUcam Pro (no filter),Registax 3 and Photoshop Elements were used. Hope the favorable observing conditions continue !

A late clearance last night enabled me to get a few shots of Jupiter at the unusually low altitude of 18 degrees (good practice for the next 3 apparitions!)
I have tried a couple of new things here. Firstly,I have used an Atik x0.5 focal reducer screwed to the camera to decrease the EFL of the Dall-Kirkham-Dall telescope and increase image brightness (whoever heard of anyone using a focal reducer to image a planet before?) Secondly,I am trying a new IR filter,the Astronomik IR Pro 724 nm.
In the past I have tried IR filters at 685 nm,which seemed to give a result almost the same as R without IR block,and at 807 nm,which doesn't transmit enough detectable radiation with my set-up for Jupiter.
The 724 nm filter seems to be a successful compromise,particularly at revealing the bright spot in the NTrZ (or is it the NTB?),which is not very apparent in the visible light image.

This is probably one of my best image of Jupiter! I have finally resolved a hint of the spiral vortex inside Oval BA!! This was very clear on the HST image.
Both the GRS and Oval BA are moving very closer now! They will have a conjunction in mid-July!
