Although I am more interested in visual work, taking images of solar system and deep-sky objects is good fun as well. For the deep-sky imaging InFINNity Deck is equipped with a ZWO ASI1600MM Pro Cool camera and a ZWO Motorised Filter Wheel for 7 x 36 mm filters. The latter has been loaded with filters for Luminance, Red, Green, Blue, H-Alpha, O-III, and S-II.

The narrow-band filters for H-alpha and S-ii were replaced in 2020 for the new versions that ZWO brought onto the market in 2018, as the old-style filters produce halos around the brightest stars.

Both Nebula and Galaxies are regular subjected to imaging.

The 10Micron GM3000 HPS is said to be that accurate that guiding would not be necessary. Taking this at face value is easy enough, but I wanted to see proof of it. For this, after having made the exposures of M27, I decided to take another few frames using the SkyWatcher Esprit 150ED APO and ZWO ASI1600MM Pro Cool camera of that same area, but now at increasingly long exposures. The longest of these was a single exposure of 20 minutes (indeed, 1200 seconds!). So no guiding was done other than having the mount following the skies based on the internal model. I think the image, which is a crop around 14 Vulpeculae, speaks for itself.

It has to be noted that these long period exposure do not work in all directions, something that is still under investigation by 10Micron and hopefully gets solved sooner or later.
