Rosette Ha mosaic 6 sessions

Still a work in progress. APP is great for doing these sorts of mosaics.
5000 pixel size reduced to 2000 for this.

Camera Atik 460EX
Baader 7nm Ha filter
Exposure(s) Nominally 6 x 15 x 300s
but probably fewer since some will be discarded

Heart of the Rosette NGC2244

By |2020-02-06T17:57:40+00:006 February 2020|Categories: HOYS, Nebula, News|

Data taken for the HOYS project of NGC2244 in Hydrogen-Alpha. This was taken in strong moonlight but Ha images are much less affected. RGB was a non-starter with the Moon so strong.

IC349 Barnard’s Merope Nebula

By |2020-01-07T17:25:55+00:007 January 2020|Categories: Nebula, News, NGC Winter|

Thought I’d try and get the Merope Nebula as the whole Pleiades don’t fit in my FOV. But saw a flaw beneath Merope which turned out to be another nebula.

NGC 2024 Flame Nebula RGB

By |2019-12-05T16:10:37+00:005 December 2019|Categories: Nebula, News, NGC Winter|

Wasn’t expecting it to be clear so this is a bonus. Only managed 5 of each colour though so quite noisy and Alnitak overpowers eveything.

Fish head nebula (IC1795)

By |2019-12-05T16:01:34+00:005 December 2019|Categories: Nebula, News, NGC Autumn|

This is a bit of a weird looking one! Stars to the left aren’t good shapes – probably combination of optical alignment, focus and collimation. Stars are over-processed too – should have been so much better.
