Can anyone confirm (or refute) - have I imaged Ganymede and Europa in orbit around Jupiter or is that just wishful thinking? (Only equipment used was a Lumix G7 with 150mm zoom lens - effectively 300mm with 2x crop factor - and of course a tripod).
It appears to be the case and yet I can't quite allow myself to believe it...
Thanks from an old newbie.
Posting in this forum after too long!
One of the first attempts at taking photos of the moon.
All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there.
Basic editing in cellphone.
Thank you! Suggestions highly appreciated!

Absolute newby here - my first foray into astronomy. I bought a Saxon 1400mm 6" refractor secondhand complete with a EQ mount for a bargain price and I'm keen to get it working properly for both planetary and deep space observations.
I invested in a few extras such as a laser collimator and a 3x barlow. I think I have a handle on how it all works including the EQ mount. I took the scope out for a test over Easter - which just happened to coincide with a ISS transit of the full moon. Rippa, I thought, that would be great to capture on my first night of observations. The problem I have is the complete inability to focus the scope to anything like sharp enough.
I have some photos I took with the scope attached:
The scene with the normal camera lens for my daylight practice session
A shot of a distant house with the telescope (using a Nikon D7000 on a t-mount adaptor)
The same house with the barlow attached
A shot of the moon- no barlow - as sharp as I could get it - certainly no way to see the silhouette of the ISS with the scope this out of focus
When I was collumating the scope, I noticed a that the reflection on the primary mirror was not a single spot but rather a line
... which means that the laser on the collimator target is a line rather than a dot
I confirmed that this is not a problem with the shape of the laser beam coming from the collimator by showing the shape on my hand at a distance of 14m
I'm not sure if the distortion of the laser is the fault of the secondary mirror or the lens(es) in the bottom of the eyepiece mount. I'm also not sure if this distortion is what is causing the inability to focus the scope, but I suspect that both issues are symptoms of the same problem.
I'd appreciate any ideas on what to do next to resolve the focus issue.
