IC434 - Horsehead nebula - H alpha channel

This is my first project with a Newtonian telescope. I had quite some trouble with collimation and cooling compared to a refractor. I got an 8" f/5 newtonian from TS optics and I got a nice reducer from Starizona (Nexus 0.75x). The total cost of the setup is half of a good refractor / SCT. I was a bit worried that the quality won't be that good.

In the end I was very happy with the result. I took the same image with a refractor (Askar 107), and in the end I didn't notice any quality difference, even my astro-beginner wife thought the Newtonian was better, or at least the same quality to the rafractor.

It's roughly one hour of data, that's all I can afford over weeks in Germany these days...

Clear skies!

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.
