I guess a year or so ago I bought one of these from Amazon:
Today (finally) I decided to try it with my ST80 and Sharpcap. Wow! The images I got back from it after removing the lens and adding an old ep barrel were good (on a terrestrial test) with really clear images. Just need a cloud free night now to try it out!
This camera comes apart by undoing 4 screws and with a slight mod to the silver trim and some glue it was a real easy job. If it returns some good planetary pics I’ll be well impressed for £2.99!!
Hi I have set up a webcam for my telescope.
The problem I have is on my laptop the view is a small circle due to the tunneling effect.
It' that small it' hard to see on my laptop.
Is there a way to fix this or is it a case of cropping/zooming once I've taken a image.
As you can se from my pic I've just aimed at a light in the house and this is how big my pic is on screen
Trying to get my head around imaging with a DSLR and read that a WEBCAM is actually better for planetary targets due to file size and weight therefore, can I hypothetically use a DSLR afocally but on the record video setting and still separate the frames afterwards, edit and stack? Or would they be too large?
9.25 AVX with Canon 550d Rebel2.
I have Skywatcher DOB 250 Flexitube GOTO and recently noticed HD webcam in my friend's place...
(AUSDOM AW615 1080P Full HD 12.0M USB2.0)
So I received it for few of beers and managed to place it into 1.25' EP holder without any struggle.
I haven't removed any filters from webcam, just wanted to see if it will fit in and it did, so I was really happy, but...
(unfortunately word "but" always comes after word "happy"),
but... the only thing I can see on the screen is my Primary and Secondary mirrors
I think, this webcam would be perfect for collimation however, what to do next?
I want to see something more than just mirrors, - Moon and Jupiter maybe...
I tried to attach 2'' adaptor which comes by default with the telescope to increase the distance between mirrors and webcam... the result is the same.
I also used flexitube ability to shorten the tube and reduce Focal length, - no result, just the size of the image is different.
Should I try Barlow?
It has been too long since I contributed anything to the forum, so I thought to share with you my latest try in planetary astrophotography.
Actually it is my first try with SW 300p Goto Flextube dobsonian which I recently acquired. I wanted to try out how the system tracks for webcam astrophotography, which is my second point of interest after visual observing. In short - it tracked quite well - no jerkyness in tracking, very smooth, stable and centred for a long time, and I am also very happy with my old motor focus which helped me out tremendously. The conditions were very poor though, and the resulting picture is heavily post-processed. At least it managed to capture the colour quite nicely.
For caputre, I use a modified Prestigion PWC2 webcam, Baader 2.25x barlow and UV/IR-cut filter.
You can see the imaging setup in the second picture.
