… but it didn’t go well! I took a few shots with the 2x barlow but when I checked them on the PC, they were just like bright fuzzy blobs. Which has led me to the conclusion that I’m using too high an ISO setting on the camera and am therefore over-exposing the image. In my head, I just assumed that because the sky is very DARK, I’d need to use ISO 1600 … but I now think that the sky may be dark but Jupiter is actually quite BRIGHT, so a lower ISO setting will actually work better.
Unfortunately, Jupiter disappears behind our house quick sharply, so I’m out of time tonight – but this will be my experiment on the next clear night: to use different ISO settings.
(And, by the way, turning the telescope tube round worked a TREAT! I even got to sit on a chair while I was taking my pictures!)
This is my first bash at Jupiter with the new camera – it’s not great, but it’s a starting point!
I need to get the step ladder out, as I have to look into the camera in order to try and focus but the size of the camera makes it too high up for me (even with the telescope legs at their lowest setting). I tried standing on a garden chair tonight but that made me too HIGH and it was killing my back having to lean over! It’s very hard to get a focus because I’m looking into a tiny wee camera viewfinder so I think it’s a case of trial and error – take a picture, check it on the computer, re-focus and try again etc. etc.
Am looking forward to trying with the moon again next time it’s up and about – think it’ll be an easier target for me to practice with!
UPDATE (an hour or so later):
Just struck me that I can just turn the telescope tube round a bit, so that the bit for the eyepiece / camera etc. is at the side, rather than the top … then I don’t need a step ladder! I don’t think there’s a reason I can’t do that?!?!
I’m feeling a bit frustrated at the lack of clear skies just now! I’m sure I’m not the only one, but I hadn’t realised quite how frustrating this would be!! The way my back garden is with surrounding houses etc. I can only see the moon probably from about the first quarter to maybe the last quarter if I’m lucky – at other times, it’s either hidden behind trees/houses or is rising too late in the night. The only thing that’s keeping me positive is that it’s getting dark earlier now and the clocks go back next month too, so I should hopefully be able to make something of the moon when it’s in its later phases of rising in the morning and setting in the evening, since it’ll soon be a lot darker in the late afternoon/early evening than it is in the summer.
(I know the moon isn’t the only thing in the sky, but I’m still learning so I need to practice on the moon quite a bit first!!)

The t-ring is finally here (thanks Royal Mail, for holding it up so long…) and I’ve checked the camera with the t-ring and t-adapter and it’s all perfect. Now I just need a gap in the clouds again. It’s cloudy just now but according to Weather.com, it’s going to be clear by 8pm. Might have a bash at taking a picture and see what I can get. Unfortunately I won’t catch the moon tonight since it’s not rising until after midnight, by which point I’ll be safely tucked up in bed … but I might try Jupiter.
This isn’t a patch on what I could see through the telescope, but it’s my first attempt at capturing Jupiter with the NexImage:
In the telescope, I could make out the four main moons of Jupiter as well, but NexImage didn’t pick them up. In fairness, it’s not a great night – quite a lot of light clouds around, so not the best night for photography!
Still no t-ring today, so I gave Telescope Planet a ring and they said it was posted yesterday. Next day delivery it is NOT (given that I ordered on Sunday) but hopefully that means it’ll be here tomorrow.
This is at f/10.
Had another bash at Jupiter and could see the two main stripes quite clearly in the telescope. Got closer to capturing a picture of it this time, but just as I got everything lined up and started to focus … the laptop went into power saving mode and switched off!! This happened a couple of times and was really starting to irritate me, so I moved onto the moon since it had appeared by that point.
We’re forecast to have a couple of clear nights, so hopefully I’ll get out again tomorrow.
Here’s the moon video that the picture was generated from:
