M92 (NGC 6341)

2020-05-05T16:52:38+00:005 May 2020|Globular Cluster, M91+, News|

240s exposures in each of RGB this time instead of my usual 180s. Strong moonlight though but APP dealt with the gradients pretty well. Much deeper into the fainter stars.

Deeper version of M13

Decided to try 240s exposures in each of RGB this time instead of my usual 180s (chosen to balance detail and LP) and it seems to have worked well, especially since there only 5 subs of each colour. Much deeper into the fainter stars too.

M92 RGB

Because sky conditions were very poor I went back to globulars as nebulosity can easily disappear in LP and fog. APP got rid of the massive gradients and LP quite well I think.

M3 (NGC 5272) RGB just a few exposures

2019-03-14T09:57:11+00:0014 March 2019|Globular Cluster, M1-30, News|

Just a few exposures between gaps in the clouds. L not used because of dust on the filter.

M15

First proper imaging session of the season. New mount (EQ6-R) is guiding well with an RMS error of about 0.6″, Coma corrector is working well too. Stars are sharp right to the edges.
