  1. Here's a thread I started some time ago detailing my battery box. Yes you are right - I have connected up some cigarette lighter style sockets for use with the battery. http://stargazerslounge.com/topic/164296-leisure-battery-box/
  2. In my experience leisure batteries are the way to go. They might weigh a tonne but they will power you all night flawlessly and are fine to be drained and recharged. Mine has close to 100Ah of capacity and I have run my GOTO, Laptop, DSLR and dew heaters for over four hours with no issues.
  3. No worries. Should be in a position to get my grubby mitts on one early next year hopefully. for the moment i'm just irritated because the PS3 cam I have seems to be pretty poor compared to others. However the comment regarding two 'types' is interesting.
  4. Quick stupid question but does the eyecam save the preview frames to memory? Would this cause a crash?
  5. I've not downloaded / used the SDK. I managed to SharpCap to adjust the framerate and therefore exposure time but obviously this is useless when the noise is there. Is there anyway of telling if the camera is good/bad from a model no? Is it just blind luck?
  6. Hi Cath That's not really an option at the moment as I can't really afford one. There have been some cracking results from PS3 eye cameras, I just seem to be missing something.....! Cheers anyway.
  7. Had one of those nights you would rather forget last night. Managed to get a good polar alignment approximation through my polarscope, and got everything set up and then it seemed to go wrong from there. Couldn't even get my CGEM to align and calibrate properly even though I have done it many times before, just didn't seem to want to play. Gave up in the end and just manually drove to targets. Then the main issue started arising with the PS3 camera that I have acquired. The camera seemed very, very noisy and I still couldn't seem to find any but the very brightest stars ie Vega, Capella. What sort of settings are people using for the PS3 camera; is there a routine to go through such as setting it up in camera software first before opening PHD. Then my laptop kept crashing out about a minute after turning on the PS3 camera. It did it in PHD, SharpCap and the PS£ driver program. Has anyone else experienced this? Thanks for any help.
  8. Cheers for responses. I've got a PS3 camera for under £5 on eBay. Will give this a go. Presumably once the windows drivers are installed PHD will see it as a standard webcam?
  9. ********** PLEASE DELETE THREAD *************** I've created a new thread in getting started in imaging.
  10. Didnt seem to get any response in discussion so I have added this thread to Getting Started - I have done a little bit of manual guiding using my Logitech webcam through a StarTravel 80, but this has been imaging Orion Nebula where there is an easy bright guide star to use. Last night, I tried to venture further and have a go at other targets such as Pinwheel galaxy and Whirlpool Galaxy. Both times I could not find a guide star at all through the webcam using SharpCap. I was initially going to use this as a test and then have a go at using PHD for the first time, however gave up as I just couldn't find a guide star and just did a couple of 30 second unguided images. The webcam can pick up brighter stars such as Capella and Procyon (used these as part of my alignment process) but really seems to struggle on anything else, even with frame rate, exposure and gain pushed as far as they'll go. Would PHD be able to push the exposure of the webcam to be able to pick up stars or am I going to struggle from the outset? If so is there a cheap(?!) entry level guide cam available out there that someone could recommend? Cheers Jim

  12. Buy direct from Europe. With the exchange rate at the moment it is closer to £100.
  13. Sorry but can't help you here. I have a 450D and don't seem to get that error. Older camera maybe?
  14. Thanks again William. As soon as you mentioned the blue levels in my Orion I figured that must be the issue with the Jupiter shots. This was my first attempt using DSLR video option but obviously would help to get my white balance sorted next time. I also had a go with my webcam as well. 1,000 frames taken and stacked using AutoStekkart.
  15. Right. Had another go with my stacked file and followed Oddsocks immensely helpful tutorial and here is what I managed to come up with.
  16. Thank you so much! I will sit down and read both post properly and digest when I get home.
  17. Cheers William. That's a massive improvement over my efforts, wow! Did you change the levels / curves at all? I'm trying to read up as much as possible about processing images, are there any resources you would recommend? Not sure if you saw my thread about Canon LiveView but I have a massive blue tint on my Jupiter effort as well as apparently this image. Obviously more noticeable on Jupiter. Both sets were with camera at prime focus with no filters. Any ideas what might be causing the blue bias in the images? I'm definitely aware i'll have to start adding darks, flats etc., this effort was more about testing my rig out after a long hiatus but thanks for your advice. Jim
  18. Also, quick stupid question but how do you attach an image as a thumbnail as opposed to a download link?
  19. Here is the image obtained after stacking using AutoStekkart. out_3_g3_ap6_conv.tif
  20. Cheers for the replies. Camera is an unmodded 450D and I didn't have any filters. I attach directly to the SCT using the 2" T-rings, an all my filters are 1.25"......
  21. Hi all, On Saturday night I had my first go at using the EOS video recording software for the Canon using LiveView at prime focus on my SCT. I used Jupiter as it seemed an easy first target and I had already done some capturing using a webcam. Whilst the resolution seemed very good, the whole video is rather blue. I haven't got the image at the moment but I will update this evening when I get home. The settings as far as I can remember were fairly standard at ISO400 and shutter speed of approx 1/30 second and a daylight white balance. Does anyone know why this would have happened? Would I need a UV/IR filter? Cheers!
  22. After finally getting my CGEM working again and a lovely clear night last night, I decided to get back to trying to image. I had a go at Orion Nebula to test out the gear and get myself back into swing of things. Used Canon 450D with my 8" SCT, and manually guided using a piggyback 80mm refractor and webcam. Focused the Canon using a bahtinov mask. Took 7 exposures for 30 seconds at ISO400. Stacked using Deep Sky Stacker and tweaked levels and curves using photoshop. Orion Nebula - 210215 #2 small.tif I'm happy with this first effort but I am aware that a lot of practise will be needed with all aspects of the process, as well as far more exposure time and getting my camera settings correct. Any feedback gratefully accepted!
  23. Finally all sorted! Managed to order a second hand NXS hand controller from eBay and flashed it CGEM. Worked straight away. Very happy. Even better is that FLO have been fantastic in their support and and happily accepted a return on the now superfluous motor board for a full refund. Top marks to them and I would post a review if I had enough posts...... So now an apology is in order for the rubbish weather recently, as I am sure newly repaired scopes are just as bad as new purchases. My bad....!
