  1. Jessun... I followed what you said and its weird. The red rocker light came on and switched off as expected. However there was no power to the outlet. i disconnected everything, reconnected now the rocker switch light will not turn on but there is power to the outlet. ?
  2. Ok I need a little help here with an EXTREMELY simple circuit that is causing me grief. I put a battery box together with one rocker switch and one 12v outlet...simple right? Problem is that the outlet has power no matter if the rocker is on or off! not good.... I have it wired as such: (RED)Hot center from outlet spliced with another RED wire into HOT rocker terminal and FUSE to Positive on the battery (BLACK) from outer terminal on outlet spliced with another BLACK wire into neutral Rocker terminal then on to Negative on Battery Any ideas??????
  3. Squeaky what did you use maniuplate that image? Thats so much better than what I had done. I was out imaging last night and I took dark avi's of each object I was imaging. However I am having a heck of a time with Registax incorporating the darks into the avi. That amp glow on the top left of the image is impossible to get rid of! I've seen others here get rid of it but so far im not able to.
  4. Ill be outdoors this evening and will focus on one object. I will try capturing darks this time and attempt to stack them correctly. HOpefully with the addition of darks and an orion skyglow imaging filter I will be able to get some better results
  5. Yes I removed the filter. I now have a Baader IR/Uv cut filter screwed into the nosepiece. Im hoping to get outside this evening as it is supposed to be nice weather. My setup now consists of this ( un-tested ) . scb-2000 ---> nosepiece ---> ir/uv cut filter ---> gso .5 reducer ---> orion imaging filter. Hopefully these are in the correct order
  6. Good morning all... I captured about 2500 frames in an avi file of M51. I used a GSO .5 reducer with a baader ir/uv cut filter screwed in place. After I stacked them in Registax I began to correct the image in Fireworks CS5. Here are the before and after images. Can someone tell me what I am doing wrong? There is so much distortion in the post image that it makes it hard to see M51. after processing Thanks!
  7. The skies cleared up rather nicely last night over South Elgin, Illinois. So I setup in the driveway to test out my new KWorld DVD USB capture device for the SCB-2000. I also utilized the Gstar-EX capture software( http://www.myastroshop.com.au/guides/gstar/index.htm) I had a small list of objects to test with. NGC 4565, M51, Orion Nebula, eskimo nebula and Saturn. I used Orion as my first real test target with the new software and capture card. Orion was low on the horizon but I managed to get some footage of it before it disappeared behind the my rooftop. I had the frame integration on the camera set to x512 and manually adjusted the brightness and contrast within the Gstar program to cut back on light from street lamp in the cul-de-sac. This video is only 4 seconds in length so you will have to pause it to get a good look at the colors. I was able to pull out some nice purples, greens and dark blues from the nebula. My camera still has the OEM IR filter in place. This needs to be taken out ASAP and replaced with a proper IR/Cut filter. i ordered one from Orion but it is on backorder. orion nebula - YouTube Next up is the Eskimo Nebula. Unfortunately it is only 1 second long so you will have to pause. eskimo - YouTube Next up is M51. The video for this is not worth posting due to the length. I was confused as to the correct method of collecting frames with the Gstars application but I have since figured it out! Next time will be much better. Anyway, when I slewed the C8 to M51 it was beautiful even with the light pollution! M51's spiral arms slowly began to form on my screen as well as the nerdish grin on my face. This is exactly why I am doing what I am. Next on my hit list was NGC 4565. My results were a bit mixed. I had changed so many settings on the camera and software that I think I did more harm than good. This image is not great but you can pick out some structure. Lastly... Saturn. When I imaged this Saturn was relatively low and directly over the supernova streetlamp in the cul-de-sac but it turned out ok. I wish I had a barlow! Well I do but not a 1 1/4". This would have been much better with some magnification and a proper collimation on the C8. But her it is.... SCB-2000 Saturn First Light - YouTube
  8. I decided to have a go with the SCB-2000 video camera. I used a GSO 0.5 focal reducer in front of the CCD to make the C8 a bit faster for imaging and had C8 mounted to the Atlas. After a very accurate polar alignment I attached my telrad and camera to the C8 and rebalanced everything. The first issue I encountered was that the Dazzle capture device decided not not work! I uninstalled and reinstalled the drivers, rebooted, killed 2 chickens but to no avail... blank screen! The temperature was about 41 degrees with a nice stiff wind at my back. I had an older LCD tv with me as well and decided to use that. Success! That SCB menu was on the screen and I went about applying the recommended settings from the growing group of SCB user on the net. After everything was completed I performed my 3 start alignment for the Atlas utilizing the camera and LCD screen. I used Sirius as my first alignment star noticed that the background was quickly becoming overexposed. Sirius was visible as a very bright star on the screen but as the frame integration progressed the background became washed out and grainy. I reset the integration and a few other settings and things became more tolerable. I continued my alignment and was ready to begin. The first object, although low on the horizon, was M42. As the camera began to resolve the field the trapezium popped into view. After a few seconds the screen became grainy, bright white like before. The nebula was visible but it seemed impossible to find the correct setting combination to keep the contrast dark and allow M42 to be shown. I have watched a few videos of this on youtube and these folks did not seem to have the same issues I was encountering. Perhaps a light pollution filter would have been appropriate at the time? My location wasn't the darkest and I suspect that had a lot to do with problem I encountered. I began looking for something a bit higher in the atmosphere. I found NGC 2244 ( Rosette Nebula ) around 29 degrees above the horizon and slewed the mount to it. Once again I began resolving the core stars and just as some detail began to emerge the screen began to white out as before. I set the frame integration from 8 seconds to 3 seconds and the screen became darker but i lost the emerging detail. I began toying with the settings on the LCD itself to see if I could compensate but the menu system was horrendous and I think I actually did more damage. I reset the LCD and SCB camera settings to default and began again. The wind was blowing harder and it was getting much colder. The final object was the double cluster. I slewed the Atlas and the Double was centered perfectly on the screen. I adjusted a couple of setting on the camera and the double popped out on the screen! The frame integration was set lower so the screen was darker. Still not what I was expecting to see but getting a bit better. I ordered a Baader Planetarium IR/UV cut filter to see if that will help it out a bit. I also ordered a new USB dongle type frame grabber that has proper drivers for Windows 7.
  9. Cornelius.. I contacted Orion and they told me that under no circumstance should the mount not slew faster after the Rates have been set to 9. They are sending a replacement controller today. I'll give it another shot as soon as it comes in. Thanks!
  10. Yes, i set it to 9 but it made no difference. if i look though my finder scope it is moving, albeit extremely slow. so slow that it would be impossible to perform an alignment. Standing there it does not seem to move at all. its as if its set at the default, i think, of .5 and never accepts the Rate increase. Do you think this is a call to Orion?
  11. I did what you said just now and the scope motors make a sort of low whine when the buttons are pushed, but it does not slew like it does when its automatically trying to find an alignment star.
