Struggling.

Just been out and took 37 pictures of andromeda, took me about 3 mins.

Loaded all the images into pipp, cropped them and then prosessed into both avi an tiff.

Tried them both in registax and it won align all the pics, end result looks like images just randomly placed on top of each other.

I was taking the pics until the object was almost out I the view finder then I'd move the scope slightly and shoot again.

?

Don't use Registax for stars and deep space objects, use DSS.

Also, how much data are you getting? 37 subs in 3 minutes can't be more than 2 seconds each.

Like Frugal say use DSS much better results i will testify. For andromeda you're really going to want at least 3 minute subs. Just some advice.

[NIGHTBOY]

Even so though if all the pics were aligned in pipp then they should stack ok in registax yes??? You can see andromeda fine in a single pic. My cameras ISO goes upto 12800, I was on 6400.

The thing is that Registax is design to stack planetary objects (big things with curved edges). DSS is designed to align and stack starfields (lots of little points)

Ahh Frugal I see, will check it out!

[NIGHTBOY]

Will I still need to run them through PIPP?

[cgarry]

You should put the images straight in DSS, nothing else required before that.

Cheers,

Great will give it a go. I couldn't video Andromeda with my dsrl as the iso wouldn't go high enough to get a picture so the camera kept turning off the videoing mode.

One thing I did notice on a video of Jupiter I took the other night is on the screen there is what looks like a single red pixel. Any ideas???

[cgarry]

A single red pixel in the same place in every frame?  If so, that just sounds like a hot pixel.

[NIGHTBOY]

Yes that's exactly it. Is that a fault?? (cameras fairly new)

[cgarry]

Faulty pixels like that are quite common and should not affect the final image.

If it's any consolation friends and I accumulated 47.5 hours of data on M31 and still found it a bit tricky!!! Time, time, time....

Try dropping the ISO to 800 and taking "37 X 3 minutes "  rather than 37 in 3 minutes.

[brantuk]

If you're tracking manually your results are going to be severely limited - especially on the deep sky like M31..... I doubt you'll get a 3 min exposure out of it. Which scope/mount are you using?

If you are starting out in AP, have you got hold of the book 'Making Every Photon Count' from the book section of the FLO website. It really is something of an imaging bible, will explain about stacking etc, then gives you some processing help as well - Trust me, you'll benefit from that as well. A great book giving you good information.

if the planet is moving round slightly in the video then when you stack it all (especially with median, sigma clipping or the like), the hot pixel will get averaged out.  If you take darks too, the red pixel will be on those as well, and will get subtracted immediately, and if the worst comes to worst, you can always zap it on the final image in photoshop with the spot healing brush.  So nothing to worry about, and as Chris says, all too common
