Taking Flats?

It does use them - it just warns you that they're not the same.

A light box definitely seems like the way to go. It will make taking flats much easier and I wont have to worry about keeping the camera orientation and focus exactly the same every imaging session.

Thanks for the help.

Your Right, After leon's post in deep space re DSS vs IP, I've been trying every stacker going lately and now I'm just so confused, I don't know which one does what

I just found this arcticle written by Barry (bloodhound31) on how to make a Light Box.

I might attempt making one myself, it doesn't look too difficult.

No, it's dead easy, just watch out for the light bulbs.
You need a true white light and I believe halogen bulbs will give closest to that.
Bunnings have 12v 10watt halogen bulbs for about $2 each.

Flats = ? = whites ??

This is a fantastic unit from AstroHandy, makes taking acurate flats "at anytime" very easy

Isn't that thing around US$250 !

The light ring looks great.......but that salesman......

[MrB (Simon)]

Halogen is definitely yellowish. I was going to recommend white LED's, but seems the unit above, with dodgy looking salesman, uses both... even better.
White LED's(and some Cool-White flouro tube's) look blueish compared to other light sources, but is infact closer to white than any incandescant, and the sun for that matter.
Dunno if any halogen globe's include their colour temerature on the labeling? Most flouro's do.

I bought a cheap plastic crate lid from Bunnings and cut a diffuser out of it. It´s nice and uniform and around milk bottle colour.

I got a 255x255 piece of milky plexiglass for $10 from a plastics shop. The mylar is for the initial diffuser inside the box. I'll try a drafting supplies shop today. I also found white festoon LED lights at dick smiths which I'll try out. They are meant for the interior lights in cars and have 4 White LEDs in each bulb.
