||Moon pictures from July to September 2018
On these pages we show our single frames
of the moon, taken in July, August and September.
In total we present 150 very high resolution images
taken on a total of 21 days. Most of the raw avi files were taken shortly
before sunset or in early dusk. This short period offers the best seeing
conditions on Onjala.
All raw avi
files were recorded with a ZWO ASI 290 at a pixel size of 2.9 mü in the
primary focus (f = 3.900mm) of the Onjala Celestron 14, to calm the seeing, a
Baader IR pass filter was inserted into the light beam path.
The raw avi files each consist of 2,000 individual
images of which an average of 10% were stacked. Stacking software was
AutoStackert, the raw sum images were sharpened with wavelet filters in
AviStack. The finishing was done in Photoshop CS 2.
