M 87 (Michael Timm)

M 87

My plan was to capture the relativistic jet produced by the outskirts of the supermassive black hole in Messier 87's center. Well, i achieved that goal but only with a bit imagination. One can see the jet, but it is no more than a small, blueish line. I think there was more possible. A monochrome camera with some nice narrowband filters would have done that job way better. But anyways - i decided not to go narrowband when i started imaging and i stand behind my decisions. Maybe in a few years i will change that - but not before my processing skills have improved a lot. One step after the other.

So, back to the image. I started this project shortly after the great success of the EHT - like many others. I think that M 87 is a quite popular target these days. My first imaging session in April started fair, but not good. Seeing was good, but auotguiding was horrible. And then the clouds came to germany and stayed for about three long weeks until yesterday. We had a clear night with fair seeing, but the moon was already at about 55 % or so and the nights are getting short over here. But the autoguiding was unbelievable good. I think the reason is that i spent more time with the polar alignment, which was accurate by about 10 arcseconds in every direction - which is a good value for me. I am pretty sure that this effort in polar aligning was responsible for my good autoguiding. Mental note: Take the time to do the polar alignment right.

All in all i am satisfied with this image. I can say that i imaged a relativistic jet coming out from the surrounding of a supermassive black hole by myself :-)

Sadly enough i was not able to image the black hole directly :-p Next time i'll buy a few 300 meter-radiotelescopes, install them all around the globe and will do that :-) (Just joking.)

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.
