I took the Celestron 130SLT out for some video astronomy last night. According to the date stored in the controller, it's been almost a year since I last used it. I used my ASI224MC and Sharpcap Pro 3.1 Beta. My computer has Astrotortilla installed so it gave me a chance to try the Plate Solving function in Sharpcap (to use plate solving, you need to install plate solving software but it doesn't need to be running). I must say it worked fantastic. Most solves were done in under 10 seconds and most were done with less than 20 objects detected (With Astrotortilla, you're generally looking for a result that generates more than 40 objects). My lowest was 9 objects detected. It didn't work the first time so I slewed the scope a bit and tried again and it worked. Slewing with Stellarium/StellariumScope worked great. The mount takes a while to settle down, probably due to the 130OTA pushing the weight limit of the scope). But once I got decent stars, I started stacking and it was usually trouble free. I used Photoshop to crop the field rotation out of the image edges and adjusted the contrast/brightness and Levels a bit to make it closer to what I saw on the screen. Flame Nebula (32x8s, 350 gain) This was pretty close to the moon. M31 (32x8s, 350 gain) M32 (10x8s, 350 gain) M42 (42x8s, 350 gain, 250 gain) I started with a high gain which blew out the core for a couple of frames and then dropped it down to 250 gain for the rest of the frames. M76 (22x8s, 400 gain)

Hola Robert
I have one of this scopes, I used it for EAA and works pretty well with AZ mount.
In my opinion his limitation is the little opening of the objetive, 130 mm gives little detail in the objects and the very weak are hardly seen.
I used the Infinity for this but it has the same sensibility of the IMX224. I took the same picture of a lot of objects with Infinity/IMX224 and looks quite similar.

I actually like the Star Flare in your first image Rob

Nicely resolved stars in the M42 core
