Comet 21P Giacobini-Zinner


The Comet 21P Giacobini-Zinner, this morning UT02h15 as seen in the constellation Gemini. It's current distance is about 60 million km from Earth.


Pleiades Messier M45

Astropicture of the Seven Sisters or the Pleiades (Messier M45) can be fount in the constellation Taurus. The open star cluster is located at a distance of 444 light years from Earth.

The picture is the result of a long exposure of 40 minutes. It's a combination of ISO800, ISO3200 and ISO6400 with exposure each time 30s. Pictures are converted to DNG and stacked using DeepSkyStacker; final editing using CS4 16bits and result below is Jpeg.
The green line is probably an airplane.

Open Star Clusters NGC1039, 1342, 7281 and 7261


Astropictures from Open Star Cluster

- NGC1039 or Messier M34; the Spiral Cluster - the picture also shows Galaxy NGC1053
- NGC1342
- NGC7281
- NGC7261

All pictures made using Nikon D7500 on TLAPO 80/480 f/6. DeepSkyStacker is used to stack the DNG files. Photoshop CS4 is finally used to edit the DeepSkystacked Tiff files.

Astropictures Cluster, Nebula and Galaxy




Some beautiful sky objects :

- Double Cluster NGC884 & NGC869 in Perseus
- Open cluster M52 with NGC7635 Bubble Nebula
- Little Dumbbell Nebula M76
- NGC457 Dragonfly Nebula
- NGC1023 Galaxy
- Iris Nebula NGC7023

All pictures taken with Nikon D7500 on TLAPO80/480 f/6. Stacking done unsing DeepSkyStacker and editing with CS4. File format DNG.






Open Star Clusters in Auriga and IC405 Flaming Star Nebula


It's still "summer" but the constellation Auriga rises above the horizon in the early morning. Some beautiful Open Star Clusters can be observed like M36, M37 and M38.
I took some pictures using Nikon D7500 with TLAPO80/480 f/6. Stacking was done with DeepSkyStacker and limited editing in CS4.




The Flaming Star Nebula IC405 is located 10° west from Messier M38



Some more detail of Comet 21P Giacobini-Zinner with Messier M35

A snapshot of Comet 21P Giacobini-Zinner with Open Star Cluster Messier M35.


Comet 21P Giacobini-Zinner and Messier M35 : astrophotography highlight


An astrophotography highlight this morning : Comet 21P Giacobini-Zinner together with Open Star Cluster Messier M35. The "Green Comet" was passing in front of M35, an open star cluster in the constellation Gemini. The picture below shows also star cluster NGC2158 en IC2157.
The picture was taken with Nikon D7500 on TLAPO80/480 f/6. Editing was done using CS4.


It's interesting to see how "fast" the Green Comet is moving against the stars. Below picture was taken this morning with a time difference of 1hour.
