We return to the load, with a new timelapse, the longest I have created so far, but as in any discipline I still have a long way to go to learn this wonderful technique correctly, all comments and advice will be well received.
Last August during my summer vacation and after having to cancel our long-awaited trip to the United States for the second consecutive year, I dedicated that vacation to make the Timelapse that accompanies this publication, I tried to capture a night of astrophotography summarized in little more than 90 seconds , it took a total of 7 nights to be able to capture the night images that make up the video, at the same time that it obtained deep sky images, below I leave the results of those nights of Astrophotography. To complete the idea I had in my head and to be able to show a whole night from sunset to sunrise, the first weekend of September I decided to make my first sunset using the Timelapse technique, and thus be able to show from sunset in my town natal, until dawn.
Undoubtedly the most complicated to capture and process has been the sunset, since it requires constant corrections as the sun sets on the horizon, I have realized that this Timelapse is something that has caught me, and I hope to be able to keep practicing it for years to come.
All the images have been captured using a Nikon D7500 camera and the Tokina 11-20mm f2.8 lens, for night shots I have used the Astro-Timelapse function of the Star Adventurer mount.
Below are the two deep sky images, the result of the same period covered by Timelapse.
NGC 6914
This is a beautiful nebula that is in the constellation of the Swan, if you want to know more about it you can check the entry of Cropping the Sky and if you want to know the technical data of the image click here, although this nebula had already been photographed in In the past with the same equipment, I decided on it to be able to check the behavior of the IDAS LPS-D2 filter that I acquired this summer to be able to deal more efficiently with the LED lights that have been installed in my town, and also to be able to improve the color balance that in the CLS-CCD the red turned out to be orange, here you can see the difference.
Sh2-155- The Cave Nebula
Despite being the image with the longest integration time, of the two that I was able to obtain, (114 shots of 600 seconds) I have not been very satisfied with the result, to a greater extent due to two very close street lamps and the light pollution from Astroga Due to this light pollution the resulting gradients in the image were very pronounced, you can still see a reminiscence in the lower left part of the image that accompanies these lines, even so, we must not forget that it is a rather weak object , with a camera more sensitive than my old 1000D, its result would be improved, as for example the 2016 image that I obtained from Deep Sky West, this nebula is located in the constellation of Cepheus and is separated from us by approximately 2400 light years.
So far this entry, but I want to ask readers a question, do you like Timelapses? Have you captured any?
Greetings to all and thanks for the visit.
