Exoplanet X0-2 b

By |2020-01-07T19:51:22+00:007 January 2020|Categories: Exoplanet, News|

Second attempt at an exoplanet. Dips in light curve caused by a moving dark patch in light train – possibly dust or condensation. Would be better data if not for that.

Qatar-1 b First Exoplanet

By |2020-01-07T19:54:04+00:007 January 2020|Categories: Exoplanet, News|

Been on my list to detect exoplanets for ages and finally got around to doing it. The data is messy and needs to be improved but it does fit the transit.

Top line shows curve before detrending – probably due to airmass changes. Quite serious clarity variations during session.

IC349 Barnard’s Merope Nebula

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

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.
