Trapezium Region, with planetary gear

It has come to my attention that English doesn’t really have a word for self irony. Well, Hungarian does, and it is a word needed when mentioning balcony-observatory-survey all together. So this is my home observatory I really like, but due to several factors, it’s all I’ve got. HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher

So, I continued looking at binary stars, after the first and second surveys. This third post comprises of the observations made since the second one. The processing is the same, some artistic license is applied, so the vibrant colors and the shape of the stars is the result of editing – those colors are there though, just not that vibrant.

Though the Trapezium started out as a „binary” ie planetary-technique, it has become deep sky, but with the very same gear.

And all the binaries I have photographed so far are these.

I had both some time and clear skies to image yet another colored binary.  I used the HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher setup well known by those who follow my posts, and the heavy processing described here. The main issue with these binary stars is that they are faint, and their companions are even more so, so even my mountpusher has a problem following the target — the mountpusher needs at least two-three frames per second to not beep and have the time to apply the needed corrections.

Some binaries, like Albireo and Alcor-Mizar are well known, other less so. This time, using my program like always, I dug out two binaries I had no reason to hear about. It’s not exactly „yet another balcony survey„.
