Markarian's Chain (M84, M86, M87) - 29.3.2023 at 22.54 - 29.3.2023 at 23.53 Janakkala, Tervakoski Observation number 113935

Visibility III / V

Kuossari Petri, Riihimäen tähtit. yhdistys

It was a bit too much adjustment for the evening at once. I watched the rocket launch at about 22:30 onwards, while the Vespera tube imaged the M86 mosaic, eVscope had two supernova alerts lined up, at At 23:00 the second supernova recording ended and I started a new one over a minute at 23, I checked again that the trees do not come in front of the observation and at the same time with the side eye if the rocket launch can still be seen, then I thought I would have time to send the report to the Seti Institute on the computer inside and quickly go back outside to see if the rocket could be seen. It wasn't visible, well I thought that the launch window was open until midnight. The next supernova report, when I went inside to do so, I noticed in the skywatch that the launch had already taken place, so of course the two minutes I was inside ..!! Well, what I learned from this is that you should adjust as many devices and observations as possible at the same time if you don't want to see a rocket launch. But here is this M86 mosaic.

    • Spiral galaxy info

      Spiral galaxy is a stellar system where there are outwards arched spiral arms from roundish (spiral galaxies) or bar-shaped (barred spiral galaxies) central condensation.

      The apparent shape of spiral galaxied depends on out observation direction. From above they are quite round. From the side they lens-shaped with a bulge in the middle.

      Generally a rather large instrument, good weather conditions and observational expereince are needed to see spiral arms. Usually spiral galaxies look like a fuzzy spots.

    • Elliptic galaxy info

      Elliptic galaxy is an oval or roundish shaped distant stellar system, which have no spiral arms. These galaxies look as fuzzy spots with telescopes.

    • Irregular galaxy info

      Irregular galaxy is a stellar system without clear organized structure.

    • Galaxy cluster info

      In a galaxy cluster there are tens or hundreds of galaxies. Typically a moderate big instrument is needed to see galaxy clusters.

    • Lenticular galaxy info


      A lenticular galaxy is a type of galaxy intermediate between an elliptical and a spiral galaxy in galaxy morphological classification schemes
