Noel Carboni compared two sets of M101 data taken using two different imaging systems (but the same imaging camera) at the New Forest Observatory. The top image shows in excess of 5-hours (total) data, probably nearer 8-hours, taken using the … Continue reading

The Virgo/Coma galaxy cluster featuring Markarian’s Chain

A slightly more careful processing of the earlier data.  At least 4 asteroids in there and North is to the right 🙂

The Virgo/Coma galaxy cluster including Markarian’s Chain

I found a couple more frames lurking in the archive, as well as realising that I’d lost a few with M89, M90, M91 🙁  I will have to retake those again.  This massive field of view is precisely what I … Continue reading

IC 1831 region in Cassiopeia – Milky Way star field

North is to the right in this Sky 90/M25C image comprising 33-subs at 590 seconds per sub.  I went very deep with the Sky 90 for this one under almost perfect sky conditions.  To the left of the image the … Continue reading
