First light for the new Hyperstar v4: Pacman Nebula in Ha

09.NOV.2019 - Celestron Edge HD 1100 + Hyperstar v4

7 x 600s Baader Ha HighSpeed f/2 Filter

Image A:

A short exposed Pacman serves as the first light of the new Hyperstar v4

and is mainly used to check the collimation result.

Weather forecast is currently not very encouraging, further project have to wait...

Image B:

With the picture picture B I would like to show the comparison between

the versions v3 and v4 with 400% standard stretching in Fitswork.

The images are raw shots before stacking and image processing.

The weather conditions certainly were not exactly the same.

However, it is noticeable that the v4 stars are much smaller than the v3 stars,

although the v4 image was exposed much longer at 600s.

The details in the nebula are also more detailed.

I'm looking forward to taking more pictures with this fast optics!

Image C:

comparison:

v3 / 5x-stacked 120s Ha, Gain 139, Offset 21 <===> v4 / Single-shot 600s Ha, Gain 70, Offset 50

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.
