I have used Arsenal 2 Pro for the first day today. Firstly I found install easy and quick. On use it is unclear if the final processed image is downloaded to my camera- a Z7ii Nikon. I looked for the final processed image in a stack but couldn’t locate it in camera storage. There doesn’t appear to be any tutorials on how to use each feature. I looked on you tube and the Arsenal site appears to only contain a set up tutorial. Arsenal device appears to get very warm while operating. Guess it’s doing a lot of processing. After charging the device it took about 50 min to reduce charge to 50 percent. So I guess you have to turn it off while not using it in a shot. Any long exposures and time lapse with Arsenal will need a large backup battery to complete the task especially if it’s a long astro session. On the focus stacking the feature of setting the near point and far point seems to be missing, instead you have figure out how many shots and the span between focus points to get a near-to-far focus stack. Then I can’t find the final image on camera. Maybe it went to the secondary SD card? Need to watch the ISO if the mode is in aperture priority. If it’s low light, it assumes you want a high ISO, but I usually don’t so you need to dial it back manually. I’ll try some more another day and see if I can find the truck to fix these things. Not so far though.
