A quadruple dataset for M13

I just used Registar to add two earlier original Hyperstar M13 datasets to the very recent (2) datasets taken using the Hyperstar III.  This is the result 🙂

Vega from the mini-WASP array

Testing out the re-collimated Sky 90s I took an image of the Vega region using both scopes and cameras.  This is a Registar combine of both sets of data.  There is some field rotation in all 4 corners of the … Continue reading

Perfect spherical symmetry in deep-space – Abell 39!

I have wanted to image this object for years ever since I saw it in a picture.  However, being a planetary nebula I always thought it would be far too small on the Hyperstar III rig to be interesting.  As … Continue reading

Momentous day today :)

After a great deal of grief and pain I have worked out how to collimate the mini-WASP Sky 90s and they are now both sorted 🙂 Fourth clear night in a row, and no Moon, so I am imaging the … Continue reading

It’s the power of f-number

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

Every deep-sky imager knows that Full Moon = Clear skies

Except of course when the Full Moon  is a Super-Moon or Mega-Moon as it was this morning – then you get wall to wall cloud for 24-hours.

M13 potboiler from the Hyperstar III

This is literally a 10-minute process of some Hyperstar III data taken last night in parallel with me working on the mini-WASP array.  68 1-minute dithered subs with very poor collimation as I spent no time tuning up before imaging … Continue reading
