C5 The Hidden Galaxy

2021-04-14T13:59:46+00:0014 April 2021|Caldwell, Galaxy, News|

Another  go a this for the ASE Caldwell Project. A really tricky one this. Hidden in the dust from our own galaxy, this would actually be naked eye brightness if not obscured. From two sets of data but still challenging.

Another  for the ASE Caldwell Project. Horrible gradient to deal with but background is messed around with to bring out all the dust around it. Makes the rest of the background messy though.

IC 1848 Soul Music

2021-04-06T10:48:34+00:006 April 2021|Narrowband, Nebula, News, NGC Autumn|

Well the Soul Nebula Mosaic anyway. 5 panes in the end. First 4 panes (see below)  should have done it but I suspect platesolving failed and I had to do another pane the next night. APP is brilliant at stitching together and blending in panes – even from different sessions.

KELT-2Ab

2021-03-17T12:58:48+00:0018 February 2021|Exoplanet, News|

First results using CMOS camera. Was an ExoClock ALERT.
A difficult and very large dataset (33 Gb). Results are inconclusive and need verification.
Helped debug HOPS v3.0 during the process.

M42 Ha with Telescope Live in Chile CHI-1

2021-02-08T17:59:06+00:008 February 2021|M31-60, Nebula, News, Robotic Telescope, TelescopeLive|

Free trial of Telescope Live using one-click imaging (basically piggybacking onto other observations). It’s really not the same as doing it yourself, with your own equipment, from you own garden, with all the challenges. But when the weather is dire – it’s fun! Advanced, full control of the telescopes costs A LOT more. though!

  • 200mm RC8
  • 250mm Newtonian.

Cameras were:

  • Canon 350D
  • 350D astro-modified
  • 600D
  • ATIK 460EX mono CCD
  • QHY168C CMOS

Filters include:

  • Lumicon Deep Sky
  • Skywatcher LP
  • Astronomik EOS CLS
  • IDAS P2
  • LRGB, Ha, OII, SII

C3 NGC 4236

2021-04-14T14:03:13+00:0014 April 2021|Caldwell, Galaxy, News|

Added more data to this one but still very tricky. More horrible gradients to deal with. The IDAS P2 LP filter is no longer doing it’s job with the change in LP sources round here. Have now bought the IDAS D3 to see if that is any better as it deals more with LED lighting.

M51 Whirlpool Galaxy

2021-03-20T22:35:36+00:0018 March 2021|Galaxy, M31-60, Nebula, News|

Didn’t expect to get too much out of this because of the high wispy cloud and only got 9 subs, but not too bad.
