Another Guided M42

[mick pinner]

this is the second guided shot of M42.
the same 10min exp but this time with the ED100.
capture scope ED100 @ F/9
guide scope LX200 @ f/10
Canon 350D unmodded @ iso 400 and Baader UHC-S filter
this is my first venture into guiding so any comments from the experts gratefully accepted

[h0ughy (David)]

nice image, now take a few of them and stack them

[mick pinner]

thank you guys, will do Houghy.

[Tamtarn]

Good looking single shot image Mick.

A nice well balanced image there. Is it hand or autoguided?

[mick pinner]

hand guided at the moment Scott, hope to get autoguiding happening soon, although l am surprised at how few corrections l have to make during a 10 min exposure.

Great image Mick,

Mick, my first attempt at guiding (by hand) was at camp last weekend, and I found that it certainly improves an image.

I hand guided about 6 images of varying lengths, then stacked them.
I think the images are supposed to be the same lengths, dunno, but I was experimenting and I finally got some better results.

Your stars look round, so you must be doing it right.

Damn hard this hand guiding caper

Very nice!

So......how do you hand guide?

[mick pinner]

set your imaging scope on the object you want and then align your guidescope on a fairly bright star with an illuminated reticle ep.
using your hand controller then keep the star in the alignment box of your reticle as accurately as you can for the length of the exposure.
the higher the magnification you are guiding with should keep the star more accurately aligned and therefore minimal image drift.
the more accurately you are polar aligned will determine how many corrections you will have to make.

AHA! Thanks so much. That would have to be the easiest and simplest way anyone has ever explained it to me!

You rock!
