    Staring mono CCD help

    Thanks for the speedy reply. Sorry I probabaly should have said I used an unregistered version of nebulousity so the horizontal lines are an artefact that it puts in to degrade the image. I’ll upload a raw sub tomorrow for you to look at.

    Staring mono CCD help

    After a few semi successful attempts with my 60D I recently got a 314L+ from Ebay. The first night under the stars I could manage due to work and other commitments was 30/11/17. Just trying to get everything working with SGPro tried to capture some images of M1. I have a 200P on an EQ6. I was taking 60 second subs with no filters unguided. The results were less than great. My subs seemed ok, nothing amazing but ok. When I stacked 30 of them I started to see something faint and fuzzy. I wasn't expecting a lot for my first attempt with a mono CCD but I've a few questions about how I deal with the issues I have. I am imaging from the my back garden in a suburban area, I have a few street lights that shine into my garden. I seem to have a pretty bad gradient in the stacked image, I assume this is from street lights. Will a light pollution filter help? If so any recommendations, are there any other tricks to help? 1 x 60 Sec 30 x 60 Sec The other issue I have is when stacked and aligned the image has a large area of lines at the side. I'm pretty sure this because I wasn't very diligent with my polar alignment. I know guiding would help this but better polar alignment would be needed anyway. I have a DFK 21AU04, can this be used as a guide camera, its probably not ideal as its a colour. I have got it connected to PHD but I haven't had time to use it under the stars. I don't have a guide scope and was planning to convert a finder, is this a good idea or is it better to save up and get a OAG and different camera?
  3. I'm using a 200P and 60D and have some questions about alignment and rotation, I'm struggling to get to grips with this and it means that I can only use data from one session for my images How do you make sure the images you take in different imaging session align so you can stack them, especially rotation? Also how do you align you camera so the resulting image is the right way up, i.e. north at the top of the frame?

    Power supply : Work in progress

    Hi, This is all a little OTT as you would need to charge the battery without the fan running then start the fan for a buildup of gas to happen but.......With the fan in the current orientation if there was an explosive mix it would be extracting it through the fan so if the fan sparked, not that it should because its a brush less motor, it might be a source of ignition. Have you thought about reversing the direction of the fan, so it blows fresh air into the box. Cheers James

    Hello

    Hi, I've been reading the forum for a while and thought it was time to start participating I'm currently located in Reading and Somerset and have recently brought skywatcher 200P on an EQ6 mount from eBay. I have had it setup a couple of times and have enjoyed some great views, I'm still trying to get the hang of it really. I took it out for the Lunar eclipse and was struggling to get it setup, a very helpful guy called Chris, I think, helped me get going. I managed to capture the images below.... James
