Spectroscopy of Vega & M57

The Star Analyser 100 is a spectroscopic grating embedded in a 1.25" filter holder. In combination with the RSpec-software one can analyse the light of stars, quasars, other compact objects like planetary nebulas or planets. This allows one to detect methane in the atmosphere of Neptune, measure the redshift of quasars or just classify a star by its spectral lines - or decompose the ring nebula. The zero-order spectrum (the image of the M57) can be seen on the left, the decomposed images of M57 in OIII / Ha light are on the right. I used Vega's (Spectral type A0) clearly detectable hydrogen-Balmer-lines to calibrate the distance in pixels to the corresponding wavelength. The spectrum of Vega and a version with annotations can be found in the revisions. I compressed and scaled down the images so the pixelscale will only fit the 35MB version on my HD ;-)

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.
