Sun December 16 reworked using AstroSurface
My image of the Sun in H-apha from December 16, 2022 is reworked using AstroSurface. The software is able to stack my SER movie and to edit the result using deconvolution, sharpening, ... Normally I stack my pictures using AS3! and editting with IMPPG and CS4. The result is very promissing.
The picture shows an active Sun with different prominences.
Setting: SolarMaxIII 70/400 f/5.7 DS, ASI290MM
Software: SharpCap4, AstroSurface
Lights out ! 1 hour more dark sky
Great news! Starting from tomorrow onwards, December 19, 2022, my hometown will turn off the city lights one hour earlier, which is at 11pm. About 7 years ago, they have been turning the lights off from midnight till 5AM in the morning. So, one hour more dark sky!

Mars IR742nm
Image of Mars (December 12, 2022) using my IR 742 bandpass filter (above). To compare, below is the color picture of Mars using the IR/UV blocker filter.
Setting: TAL200K f/8.5, ASI224MC, Barlowx2, ADC, IR742nm bandpass filter
Mars - Edit with AstroSurface T7 Titania
My earlier images of Mars (December 12th) are reworked using AstroSurface T7 Titania - see this link http://astrosurface.com/
This free software has the ability to stack and to edit the images inclusing, wavelets, sharpen, deconvolution but also RGB splitting and merging. So far the software is an added value on the once I'm currently using.
Setting: TAL200K f/8.5, ASI224MC, Barlowx2, ADC, IR/UV blocker
Software : SharpCap 4, AstroSurface
My blog name changed
I changed the name of my blog from Orionxt to Pascalhilkensastropage.

Sun H-alpha December 16, 2022
The H-alpha Sun this afternoon, low above the horizon.
Only 500 frames taken as the sun disappeared behind branches. Flats were taken a couple of minutes before. It's an active sun with some prominences.

New Book from Marcel Vonk "Van getal naar Heelal"
Het fascinerende verhaal over hoe de wiskunde de natuurkunde vooruithelpt, en omgekeerd
Theoretisch natuurkundige Marcel Vonk laat zien dat wiskundige begrippen op verrassende wijze in de natuurkunde opduiken – en hoe die wiskundige concepten ons verder hebben geholpen in het doorgronden van de natuur. Dat alles in een begrijpelijke, verhalende stijl, waarbij hogere wiskundekennis beslist niet nodig is.
De rol van de wiskunde in de natuurkunde begint al bij eenvoudigweg tellen: hoeveel sterren zijn er in het heelal? Hoeveel moleculen bevat een gasfles? Ook bijna filosofische vragen komen dan naar boven: in hoeveel dimensies leven we? Hoeveel heelallen zijn er eigenlijk?
De rol van de wiskunde in de natuurkunde gaat echter veel verder: we hebben meetkunde nodig om de vorm van ons heelal en die van zwarte gaten te begrijpen, en in de quantummechanica worden moderne wiskundige structuren als ‘groepen’ en ‘algebra’s’ gebruikt – abstracte concepten die een concrete natuurkundige betekenis blijken te hebben, en die ons helpen de natuur beter te begrijpen. Uiteindelijk blijkt de invloed zelfs omgekeerd te werken: dankzij onverwachte hulp uit natuurkundige hoek weten wiskundigen tegenwoordig allerlei voorheen onbewezen vermoedens te bewijzen.
Marcel Vonk is onderzoeker in de mathematische fysica aan de Universiteit van Amsterdam. Hij schrijft populairwetenschappelijke artikelen, geeft lezingen, en schreef eerder Snaartheorie, Zwarte gaten en De race tegen de schildpad. Ook is hij fervent toernooipokeraar en won als derde Nederlander een bracelet tijdens de World Series of Poker.
The book will be available next spring '23

Mars in opposition and Olympus Mons
December 8th, 2022, and Mars is in Opposition with an angular diameter of 17". Clouds this morning during the Lunar Occulation of Mars but this evening 1 hour clear sky. The polar cap is still and good visible on the northpole and at 10 o'clock (east) is Olympus Mons visible. I think this is first time I captured this volcano.
Setting:TAL200K f/8.5, ASI224MC, Barlowx2, ADC and IR/UV blocker

IFTTT replaces Feedburner: AstroPage Pascal Hilkens
Recently I received questions on why people are not receiving my Blogger posts via email. In the past this proces was done through Feedburner but Google stopt supporting this software. I found an alternative with IFTTT - If This Than That. All subscriptions from feedburner are moved to IFTT and an email is generated from Twieter2020@gmail.com.
Lunar Occultation of Mars with Clouds
A lot of clouds before, during and after the Lunar Occultation of Mars. But still I was able to make some pictures a couple of minutes before the Lunar Occultation.
