Orion Nebula January 21, 2020

On January 21st I wanted to try the new heating tape to see if the optics still fog up after a short time. So I connected it to the SteelDrive II and aligned the telescope with the Orion nebula. I then took 144 pictures with 30s exposure time each. In the good 70 minutes, the optics only fogged up slightly, without a heating tape it was fogged up every 15 to 20 minutes.
The stacked live image of the Atik Inifity software already looked pretty good.

I then edited the images with PixInsight. This means preprocessing with biases and darks, then stacked, photometric color correction and then a histogram transformation.

The difference is clearly visible. However, a lot would still be possible. But PixInsight is so extensive and complex that I still have to practice a little.

You can also see the vignetting of the optics, so next time I have to work with flats to correct this.
But for a first result, it's not that bad, I think.

Starizona HyperStar 11 V4

December 26, 2020 was finally a clear night. Of course, I finally wanted to try the Hyperstar V4 with the Celestron 11 EdgeHD. So I tried it first with the Orion Nebula (M 42). Already after short exposure times the nebula stood out well. Nevertheless I worked with 30s exposure time (as I had done before with f6.3 and f10). So I hoped to capture more details on the one hand, and the image was not overexposed yet. Raw image stacked in Atik Infinity software (Atik Horizon OSC, 90 frames at 30s low gain) This is the raw image which the Atik Infinity software had stacked. You can clearly see how the stars are quite round in the center and look more and more like small comets towards the edge. This indicates that the sensor of the camera was too close to the optics. That means I will have to position the camera a bit further away in the future. Although the raw material is not convincing, I still stacked and processed it with PixInsight. Interestingly, the effect with the comet-like stars w...

PixInsight

I have further informed myself in the field of image processing. Apparently, PixInsight is the ultimate tool for astrophotography, but hard to use. Well, the whole thing is not easy. So I downloaded PixInsight and bought a book. Yesterday I took with the camera 50 bias images at -15 degrees and 25 Darks at -15 degrees and different exposure times (5s, 10s, 20s, 30s, 60s) so I'm prepared for the next few nights. I should be able to reach this temperature even in the warmer nights. I will then make the appropriate calibration images for colder temperatures. Next up is generating Flats, so I have to try how it works. I tried it with a white T-shirt in front of the telescope and photographed the sky. However, the camera continues to expose itself while the data is being read out, and so the image upwards becomes brighter and therefore unusable as a flat. Next time I will use Artemis Capture instead of Infinity software. There I can activate "Even Illumination" so that i...
