December Nebulae - fighting star halos

-

The Horsehead Nebula is almost a mandatory mandatory object to capture with every new optics. I was eager to see how the Hyperstar world do with it. Unfortunately weather and moon were not quite supportive of this plan. As even thin clouds lead to huge halos around the bright star(s) I had to discard quite a number of frames. Luckily over Christmas it was possible to collect a decent amount of data in reasonable quality.

IC443 the Jellyfish Nebula is quite a beautiful object. However, the original frame I chose contained two relatively bright stars and the Optolong filter is creating a gigantic halo around them - one was even able to the cabling of the Hyperstar within the halo. My PixInsight craftsmanship proved insufficient to fully fix that, so I tried to tame one of the halos and cropped the image to remove the 2nd one.

Shot at the same nights another image using the Hyperstar with the Optolong L-eXtreme filter - this time IC410 "The Tadpoles". Once again I had been battling with star halos, but this time they are more in the periphery and therefore maybe less distracting.

Controlling the Telescope with a Berry

One of the things that made me reluctant to seriously start with astrophotography was the prospect of spending long nights outside in front of a laptop that is tied to the telescope with a long USB cable. Nights that would typically end in disappointment and anger after I inadvertently tripped over that cable - at least that had been my experience in some early attempts.   This time I wanted to take a different approach. The entire setup should be controlled by a little computer that is directly attached to the equipment, while the control would happen remotely over the network.  I guess there are three main technical approaches that you can take to achieve this: mini-pc being controlled over remote desktop; basically using ascom and a similar imaging software as you would use in the "long USB" scenario.  "out of the box" solution from an astronomy equipment vendor like the ASIair Linux based solution using Kstars/Ekos/Indi running e.g. on a Rasperry Pi I am not sur

Galaxies at a larger scale

-

The primary focus of the C9.25 at 2350mm in combination with the sensor size of my ASI 294 is giving a field of view that turned out to be a nice fit for imaging most of the spring galaxies.   However, there are a number of objects that do not quite fit. So I spent a few nights end of April to image a with the 1/6.3 reducer. This is giving a slightly larger field of view. More suitable for some of the larger objects. In addition to the larger galaxies I tried some groups of galaxies. Here it was a bit harder to get a good fit. HCG 44 may actually be better without the reducer. The famous Leo triplet is too big to fit within the FOV - so I captured only two of them. I think they are beautiful - even as a pair.  For the really huge galaxies - like e.g. the Andromeda galaxy - as well as the large scale galaxy groups even shorter focal lengths would be required. I still need to find a good solution for that. In the meantime I enjoy how these medium sized objects turned out.
