Exoplanet TOI-1298b observations by Martin Crow
These are the latest exoplanet observations by Martin Crow.
TOI-1298 b is a gas giant exoplanet that orbits a G-type star TOI -1298 in the constellation of Ursa Minor. Its mass is 0.356 Jupiters. It takes 4.5 days to complete one orbit of its star and is 0.059 AU from its star. TOI-1298 b was discovered by the Transiting Exoplanet Survey Satellite (TESS) observatory, in 2021-09.
Martin wrote ''The observations were done as part of the ExoClock synchronous observations group. This particular transit has a depth of <5 thousandths of a magnitude!! To get useful data for this target would require a telescope diameter of at least 400mm or greater. My telescope at 235mm is too small although the dip is clearly detectable buried in the noise. The aim of the project is to combine three or more data sets from similar sized small instruments taken on the same night to increase the accuracy to that achievable with a bigger telescope. This method will help to make otherwise impossible targets viable for the majority of instruments registered on the ExoClock project.''

Diane Clarke’s The Moon & M45 The Pleiades on the 8th March 2022
A lovely image of the Moon 4.1° south of M45 taken on the 8th March 2022 by Diane Clarke.
Diane said ''I had my doubts about capturing this event due to the cloud forecast, but there were breaks starting to appear as 19.00 hrs approached, so I went to set up but there was a strong breeze forcing me to find a sheltered spot to stop my equipment suffering wind blast, the breeze was also making the clouds scud across the sky very quickly. So much so that any breaks in the cloud could disappear as quickly as they appeared the image was taken in one of these short lived break's in the cloud cover.''
Image Details: Camera EOS M50m2 using a 100mm Canon EF Lens.
2.5 sec's @ f5.6, ISO 2000, on a static tripod, with a 2 sec delay to remove camera shake.
