This probably old hat to everyone, but I found out about a setting in iOS 10 that allows you to do a full red screen; I know astronomy apps have a night vision mode but I find the keyboard is normal light in skyguide, or else I accidentally press the home key.
It also lists a shortcut to set the red screen via pressing the home key three times in quick succession.
Anyway, the details are in the link below.
Hi guys, so I finally got my HEQ5 PRO mount to track correctly and I decided to take a bunch of photos of the Orion Nebula(or at least part of it).
I took as many photo's as I could with my Canon 1000D DSLR connected up at prime focus. I used 1600 ISO (max), 400 ISO and 100 ISO all with a shutter speed of 30"
I have found these red, green and blue squiggles I think are called 'hot pixels' in all of my photo's after I've used DeepSkyStacker to merge them. They may be hard to see on here but in Photoshop they are everywhere
Could someone please explain to me what is causing this and what can I do to avoid it in the future please. I feel like I've ruined a perfect night out!
Or maybe there is a way to fix this?
I was using a Skywatcher 200p for these.
ISO 1600 30"
ISO 400 30"
ISO 100 30"
Not sure whether I am expecting too much but I chose to try M103 tonight given it has a number of very red stars in and around it. I am using a 314L+ mono with filter wheel. I took 5x120secs 1x1 for each of the 4 filters which I figured was plenty to capture the colours (although L adds nothing as you can imagine). I attach the picture below and as you can see there isn't the deep red you see in other images of M103 I have seen. I popped each stacked master into the respective channel and aligned the best I could.
Am I expecting too much or have I gone wrong or missed a step?
This was purchased in the FLO clearance sale but I had a change of plans so it is no longer needed.
It is in perfect condition, unused and comes with the Skywatcher flange for ED80/100 and 120. It is the dual speed model in red with brake.
