As a follow up - others I’ve seen on YouTube appear to need a Barlow to get the set back at the correct distance for the camera to hit the right point of focus. If anyone has useful experience in this I’d very much appreciate any pointers.

This is really helpful thank you. I was getting confused about t-ring and t-piece etc. But from your message, and some google, looks like it’s just a ring I need with the right mount for Sony and then I can connect this EP using the 42mm thread. 
 

We’ll give it a try. I expect it to be totally infuriating trying to get this to work with our 8” dob - but that’s part of the fun.

Thanks for the notes. 
 

we’ve got an old dslr with a Sony/minolta mount - presumably with the right adaptor I could connect this to what appears to be a 40mm thread on this eyepiece?

I’ll start googling and see what I can find.

Thank you. 

Hi. I bought a 2nd hand 8” skywatcher dob that came with some lenses and filters. The box includes this item - can anyone tell me what it’s for please. 
 

thanks

Great thanks everyone. It’s still amazing what we’re seeing!

I’m pretty keen on the tinkering so I’ll have a look into sorting some kind of shroud. This evening I did literally take the scope out the house and start looking within about 1 minute so not surprised if there was some dew forming. 

We’ll have a play around and see how we get on. I’ve got a basic Celestron omni Barlow so we’ll try that too. 
 

many thanks!

Evening everyone. My daughter and I are pretty new to astronomy. We’ve got a skywatcher heritage 130p flextube which we’re enjoying using and starting to learn to navigate the stars. 

Of course we’ve been trying to do some planetary viewing - but I’m really struggling to get any kind of sharp images of, for example, Jupiter. I’ve bought some BST Starguider eyepieces which seem pretty reasonable. We can see four moons sharply with the 6mm EP and a couple of times we’ve discerned some faint bands on Jupiter - but it’s still looking pretty fuzzy all round. 

Am I missing something? I’ve tried collimating the telescope and testing this on a star seems to indicate collimation is pretty good. We’ve tried from a dark sky area in Scotland in the last couple of weeks. 

Am I being unrealistic in my expectations of what we’ll see with this scope and EP?

Thanks

Keith
