These two images of Cassini and Aristilus compare the ASI290MM and the ASI174MM on the same conditions, on the same telescope. The details seem to be really the same, allthough the image scale of the ASI290 is much more enlarged, it does not necessarily show more details. The Frame rate of the 174MM was a lot higher.

I guess the real test would be to do this exercise with a barlow in front of the ASI174MM. A éX barlow would enlarge the image scale, and at the same time the frame rate would still be 40FPS compared to 15fps for the ASI290MM.

NGC3718 in Ursa Major

A very nice galaxy, which I believed to be really difficult and very dim. In the end the picture comes out quit ok, with good colors and lots of details. It’s an amazing exploration trying to identify all distant objects including quasars and galaxies many beyond the 20th magnitude.

Taken in Meldert (Hoegaarden) with the 120mm Esprit @ F7, ASI2600mc, 340x120s. Stacking and processing in AstroPixelprocessor, finishing in CC Elements.
