  1. Nice come back! Sent from my Lumia 1520 using Tapatalk
  2. You mean you don't recommend using the built-in hub?
  3. It could be that it is not enough! Last night, the humidity could be felt on the air, and the weather app showed 94% relative humidity. I took a few 20 min exposures at 10C and there was no dew. But now I worry about a noisy camera since I can't cool it too much :'( Sent from my Lumia 1520 using Tapatalk
  4. I will try that. I have a small telescope dew heater, maybe if I wrap it around the nosepiece it could help. However, I understand that the STF has integrated window heater... Sent from my Lumia 1520 using Tapatalk
  5. Hello to all, I hace been having problems with my SBIG STF-8300M. The thing is that the images are getting dewed after a while. I notice this because a faint shadow starts to grow on the image, and increases from image to image. The whole histogram gets a bit darker. I have to increase the temperature to make it go away. I acknowledge that I live in an extremely moist environment, but is this normal? Right now I got dew at 5C. I am retrying at 10C. I reheated the desiccant less than a month ago, and I keep the camera in a closed room with a dehumidifier. Let me know what you think!
  6. I currently use PixInsight and darktable for my processing needs. I only use Win for capture control of my SBIG camera. Running Ubuntu 14.04.
  7. I use AstroPlanner. Its very nice. You should check it out. Sent from my Nokia Lumia 1520 using Tapatalk
  8. Hello to all, this is my first color image using my STF-8300M and Baader LRGB filters. In addition, this is my first image processed in PixInsight. Please provide feedback on it; I don't mind constructive and respectful critique. Astrobin:
  9. Hello, Maybe this is a dumb question. I have noticed that when I am taking pictures, there is a movement in the image from one image to the next, as when you dither (which I am not doing). The movement is only in one axis, like when it is trailing, but the stars are still round! I mean, in one image a star is in one place. In the next image, the same star is a bit to the right. Next image, same star moved to the right even further. It is completely round in each image, without dithering. Would expect this is the cause of the dark borders created after stacking... Why is this? Is this the guiding? Sent from my Nokia Lumia 1520 using Tapatalk
  10. Hello to all, Can somebody let me know what to do if I get the following warning message? The frames were captured with Nebulosity and normalized, but after selecting the first alignment star, Nebulosity asks me for the CIM threshold, and then I get the error. I am doing something wrong? I tried using Nebulosity 2 and also Nebulosity 3.1.8. The camera is a color Atik 314L+. The number of frames stacked is 12.
  11. Thanks a lot for the insights. Two nights ago, I started cooling the camera much earlier, and after it stabilized I took a few test exposures (about a minute in duration). I found no dark pixels. Sent from my Nokia Lumia 920
  12. I will try stabilizing the camera much earlier to see if I can eliminate this. Regarding ice, I really doubt it; the temperatures are too hot over here. During the night, the most the camera can cool is almost zero, but not below. How can it be that the ice is present at the beginning, but not later? The camera is stored inside my house before using.

  13. This issue appears in the lights. I use Artemis Capture to take the images. I cool down only to zero because I live in the tropics and the ambient temperature at night was about 25C. Sent from my Nokia Lumia 920
  14. Hello to all, Maybe you can help me this issue. I am currently getting some strange dark pixels in my exposures, like an "bug swarm" pattern. They only appear on the first few exposures I take, and disappear later. Last night, I was taking 15-minute exposures @ 0 degrees C and this artifact was present on the first three frames but disappeared by the fourth one. Any idea what could this be? The attached screenshot shows a 200% zoom region of one of my uncalibrated lights with those black pixels. I should note that they are difficult to remove during processing, and since my guiding is fairly good, they remain after stacking. Please help!
