and for this reason you need the greatest
magnification possible.
Advanced photographers in planetary imaging use
the greatest magnification in the telescope with
eyepieces and / or optical Barlow lenses, and a
technique called image stacking. This technique
consists in the making of films of a few minutes
duration to obtain hundreds or thousands of short
exposure frames. Due to the turbulence of the
atmosphere, only a small percentage of those frames
are good. Using image processing software, only the
good frames are selected and after are stacked,
resulting in a single high-quality image. In the
internet, there is free software for processing and
stacking planetary images such as "RegiStax", among
others, in addition to commercial software.
This stacking imaging technique is also useful in long-
distance
daytime
and
nighttime
terrestrial
photography and “digiscoping”
with telescope
magnification to minimize the effects of atmospheric
turbulence.

To photograph galaxies, nebulae and other deep sky
objects, you will use the prime focus photography
technique without eyepieces, replacing one of the
four eyepieces mounted on your ROTARION with the
ROTARION PRIMEFOCUS accessory included in this
box.
Although deep sky objects are light-years from Earth,
its size in the sky is very large and therefore no
increase in magnification is needed with eyepieces on
the telescope, as they reduce the field of view.
