  1. Hi Guys, I present you the second image taken with my Moravian G4-16000 camera mounted on my modified TeleVue NP101is. Images and technical information below. M13 globular cluster and its galactic area : Full Resolution image 4k x 4k here : www.poigetdigitalpics.com/G4-16000/M13.htm Full Resolution image here : http://www.poigetdigitalpics.com/Fichiers_Divers/M13new_image_Annotated.jpg Enjoy ?

  2. I am looking to go out to a remote site with my new Moravian CCD to do some imaging soon. As I have only been using it with mains power I will need to run it off a battery. After doing a bit of research I have come down to the Tracer 12v 22ah https://www.firstlightoptics.com/batteries-powerpacks/tracer-12v-22ah-lithium-polymer-battery-pack.html I understand there is another type of Tracer called the LiFePO4 which offers greater discharges but for the sake of this thread let’s just stick with the Li-Po type. What I am trying to work out is the method of connecting the battery to the CCD. The power pack that comes with Moravian CCD is a DC 12v 5A unit. So after some checking with Tracer they recommended the Bullet bare end cable http://www.tracerpower.com/bullet-bare-ends.html Then get a DC plug as linked below to attach to the bare end. I have noted that some Tracer ‘Bullet’ adapters are rated at only 2A. This is also true of some of the actual DC plugs. Clearly I need to be careful in select the right one for 5A. Here is a plug I have seen but this does not state the Amps. http://www.maplin.co.uk/p/25-x-55mm-solderless-plug-n53gu I am not too familiar with electrics so I would really appreciate it if anyone has any experience with powering a CCD with a Tracer Lithium battery, ideally a Moravian but that should not matter. Is there a simpler solution? As with all astronomy kit it is never a straight off the shelf option… Thanks
  3. I have been generally pleased with my Moravian camera and filter wheel. However, I noticed I was getting some very odd results when trying to calculate filter offsets for my autofocus routine. I found that the wheel was not rotating to the filter requested - indeed it seemed random. Of course it was not random .... I have a 10 position filter wheel. However, it seemed that the Moravian Ascom driver was convinced I had a 12 position wheel. To get the Moravian wheel correctly configured, you have to run a configuration program. It tells you to do this in the manual. I just hadn't read the manual. As you can imagine, this led to erratic results. If I shot filters in sequence, things would go OK. However, if I tried to go back to a filter I had shot before then it would not work. Now, I shoot the flats from my 7 filters all in one go, BUT I test out the required exposure times first which means a cycle through all 7. So when I come to shoot the actual flats, I am shooting through the wrong filter or (sometimes) through no filter at all. I was never all that happy with the M31 I did back in early December 2016. There seemed an odd gradient on the left side of the image: https://stargazerslounge.com/topic/282827-m31-revisit/ So, having got the wheel correctly configured, I redid the flats and recalibrated the data. Lo and behold, the bright patch on the left disappeared. Data: Baader Blue 36 mm: 16x300" Baader Green 36 mm: 16x300" Baader Luminance 36 mm: 61x300" Baader Red 36 mm: 16x300" Chroma Ha 3nm: 6x1200"
