Blue Horsehead

With the Dark Sky week coming to an end and the milky-way core with all the wonderful summer targets starting to show their beauty above the northern hemisphere horizon, I would like to share with you what can be achieved in a short time, under truly dark skies with only a modest dslr and a fast lens.

This is a photo shot 2 years ago on a trip to the bortle 2 skies of the wonderful Wales. That was the first and only time I have seen the clouds being lit up by the stars above and not by the light pollution, an absolutely incredible experience that I will never forget.

I only wish those amazing skies would be closer and available to all of us that love the stars.

The photo was taken with a modified canon 700d and a Samyang 135mm f2 lens on a eq3 mount. Total integration time is only one hour, made up of 21x3min exposures.

I hope you enjoy this magnificent target that is close to impossible to a lot of the UK fellow astrophotographers.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
