Not photography, exactly. I am utterly ignorant of the topic of astronomy and was very surprised to see how few large telescopes there are across the world. I always 'knew' that SALT was important and was pretty impressed when I visited it on an impulse a few years ago. My sense of awe of the project was probably reinforced by the consequences of camping there, in winter, without proper preparation.  It turned out to be one of the coldest nights of that year and I had to 'wear' all my clothes on my arms and legs to stay warm.  However, I have never even considered the bigger picture of how the Sutherland telescopes stacked up against the other biggies.  I just found this:

You knew this was coming after the Photobucket issue. Neximage 5 webcam, stacked in Autostackkert 2 and finally processed (a bit too much I think) in Registax.

Yesterday's image reprocessed. Somewhat less enthusiastic, not so garish. Also, what is SA's equivalent of Radio Schack? I need to build an "electric focuser" to help with the focus. At the moment, just by touching the focus knob, sets the scope shaking, and that in turn produce a blurred image.

Tweefo, I may well be dead wrong on this, but the picture looks missaligned rather than out of focus. Could you perhaps send me/ link to the original video? I'd like to see what Registax does with it.

Ek het die video in die "Moon Cloud" album op Google picture gesit. Ek die album voorheen met jou gedeel en jy behoort 'n email te kry as dit ge-upload is. Maar al is hierdie een nie te sleg gefokus nie, gaan so 'n fokuser my baie help. Ek het weer met Registax gespeel en hierdie een lyk beter.

Tweefo ek sukkel nog om dit af te laai; so tweehonderd megs in bly ek 'n network error kry. Maar die video self lyk of die teleskoop vibreer het en van die kraters verskyn as dubbel beelde, en dis ook te sien op jou andersins lieflike foto hierbo. Is dit moontlik dat so 'n vibrasie teenwoordig was? My idee was om Registax so te stel dat slegs die tien of twintig beste raampies gekombineer word. Sal bly probeer met die download.

Hier het ek net 10 frames in elkeen gebruik, met dieselfde Registax wavelet scheme. Die stacking met Registax en Autostakkert. Hulle lyk baie dieselfde, maar die Autostack een tog effens skerper? Lê my fout nie by die exposure setting toe ek die video geneem het nie? Dit is net die helder krater rims wat double vision het, of is ek weer heeltemal verkeerd?

Mooi!

Depends on how you captured it? Colour video, multiple B&W through coloured filter?

Rigil hoe werk dit? Moet ek drie videos neem, elkeen met 'n kleur filter, (groen, rooi en geel) en die drie dan meng? Hoe?

Tweefo, wat ek bedoel is, waarmeer het jy die oorsprnklike foto/ video gemaak? Was DIT in kleur?
