Hi all, my ASI224MC arrived in the mail yesterday and I had about 2 hours of clear sky last night to test it.
I had done a bit of pre-reading on how to set it up so it worked reasonably well (thanks to those who had put up their log files and additional tips on this forum, especially Darryl and Darren). This is obviously just a first try, so hopefully I'll be able to do better with a bit more practise but it seems to have worked this first time.
A few observations I have on my experience:
- I really miss the large sensor on the DSLR, after aligning the scope and attaching the camera it takes quite a while slewing around to find the planet
- Firecapture is pretty intuative to use, after "borrowing" some of the settings others use I got a good image on the screen
- The "Crop video" function is amazing, just set it up and it tracks the planet for you!
- The Barlow gives me almost exactly a 2x larger image with the 224 - on the DSLR it gave me about 2.6x
- Recording at 240 fps is amazing, I don't miss recording at 20 fps with the Canon
- Having to almost re-start with Registax to find settings that work has not been fun, this is the part I hate the most (and understand the least)
and a couple of questions if people have time:
- I found focusing is more difficult, and at the risk of starting another flame war, do people focus in colour or greyscale? Modify gamma? Blow up to 200% in the screen? Any other tips?
- I tried using PIPP, but it seems to stuff up the de-bayering, no matter what setting I tried. If you use PIPP, do you debayer in PIPP, or let AS!3 do it?
- The three images I made (two shown below) all have a sharpened arc effect on the RHS of the planet, which I can't seem to remove. I never had this problem with the DSLR images, is this common? Is this feature indicative of something else (eg poor focus, collimation etc)?
- I have included my capture settings, anything stick out to anyone as being wrong? Not best practice?
- How does Firecapture know how big and bright the planet is (40.09")? Is it talking to the internet?
Any advice, tips, answers much appreciated.
