New Nikon D7500



This week Nikon announced the new Nikon D7500 DSLR camera. It will probably replace the Nikon D7200 and the D7500 has almost the same features as the DX flagship D500. Availability is foreseen in June 2017. It's not a fullframe camera, has 20Mp CMOS chip, 4K video and up to ISO 51000. Shutterspeed up to 1/8000s and 8 frames per second shooting in raw. Connectivity is realized using Wifi, Bluetooth and wire(less) remote features. Let's wait the reviews and other Nikon releases before making the decision to replace my Nikon D60.

Helios Averbode

Helios in Abdij van Averbode - 360° Foto Pascal

De abdij voor Averbode was zo gastvrij en zorgde er voor dat de lokale vereniging voor sterrenkunde Helios Averbode haar vergadering in de abdij kon plaatsvinden. Het was de eerste vergadering na het onverwachte overlijden van onze voorzitter Dr. Jan Cuypers. Guido Gubbels neemt het voortouw en zal de vereniging verden leiden.

De opkomst was talrijk met in totaal 11 leden. Van de vergadering onthouden we de geweldige film die Guido gemaakt heeft over de workshop "Praktisch planeetonderzoek voor de zaterdagochtend (zondagnamiddag) georganiseerd bij Lieven Philips afgelopen Januari. We mochten ook al een glimp opvangen van de Guido zijn film over het zonnestelsel. Een knap staaltje van uitwerking.

Daarna mocht ik mijn werk over "Onze zon - de meest nabije ster" toelichten. Het boek 15 million Degrees heb ik gebruikt als leidraad. Bijkomende info heb ik afgelopen 4 maanden gehaald uit heel wat andere boeken, presentaties, websites en doctoraten. Voor mij was dit een leerrijke ervaring die ik dan ik vol overgave heb gedeeld met de Helios leden.

End of Astrophysics Seminar


The last 10 weeks my Tuesday evening (together with 30 other ones) was scheduled to attend the lessons of Astrophysics. The small seminar was presented by Dr. Yves Gigase and took place @ Urania in Hove. He was able to show us more insight into astrophysics. Mathematics, physics, optica, mechanics and thermodynamic priciples were discussed in view of astronomy. The last two sessions he explained in detail stellar structure using all aspects of astrophysics. 
For those who want to know more about astrophysics and are not afraid about formulas and getting into the detail, I can only say that I greatly enjoyed it and would recommend everybody to attend this seminar training. Well done Yves.
