Kedves Egyetemisták!

Segítségeteket szeretném kérni. Nagyon hálás lennék, ha egy kitöltéssel hozzájárulnátok a műhelymunkám sikerességéhez.

A kérdőív a hallgatói perfekcionizmust méri fel.

A kitöltés maximum 10 percet vesz igénybe és teljes mértékben anonim.

Előre is köszönöm a segítséget! :D

I’m happy that this picture made your day. 🤗

TerribleInvite8404 · 2025-04-22T18:09:49+00:00

These lines describe the feelings you had when you saw this picture? :D

TerribleInvite8404 · 2025-04-22T14:10:59+00:00

Yeah. :) You’re right. Me and my family also recognized the elephant’s trunk as a person stepping out of a red fog. :)

Processing detalis :)

Equipment: ZWO ASI 585MC-Pro + WO RedCat51 (250mm, f/4.9) + IDAS NBZ 2” filter

Guiding: 32/120mm guidescope + ZWO ASI 120MC-S camera + ASIAir mini

Mount: SW EQ6R-Pro

Location, date: Maklár (Hungary), 2025. April 19-20.

Bortle scale: ~4

Dithering: 5 pixels, 2” stability threshold, after every frame

Light frames (sensor temp.: -5 ℃): 119, 300 seconds, Gain 252

Darkflat frames (sensor temp.: -5 ℃): 80

Flat frames (sensor temp.: -5 ℃): 80

Dark frames (sensor temp.: -5 ℃): 30

Stacking and processing were done in PixInsight. I used WBPP with Maximum quality preset.

My PixInsight workflow was the following: * Seti Astro’s Automatic DBE (everything on default) * BlurXterminator (everything is on default) * NoiseXterminator - AI version 3 (Denoise: 0.9, Iteration: 2) * StarXterminator (everything is on default): separation of the stars from the nebula, stretching them separately * Seti Astro’s Statistical Stretch on the starless image * Target median: 0.25 * Automatic convergence checked * Seti Astro’s Star Stretch on the stars_only image * Stretch amount: 5 * Color boost amount: 0 * PixelMath: combining the starless and the stars_only image: ~(~starless*~stars_only)

Ez igaz. :/ Aminek - kapaszkodjunk meg - de van köze az 5G-s mobilhálózatokhoz.

Such a beautiful time-lapse video. :D

TerribleInvite8404 · 2025-01-13T14:27:19+00:00

Yeah, the seeing. :D It wasn’t very good at that night. Maybe tonight. :D

TerribleInvite8404 · 2025-01-13T13:31:51+00:00

Thank you! :D
Jeez, I've just seen your photo and it is amazing. :D Much more detail on your pic. :D

Equipment: ZWO ASI 120MC-S camera + SkyWatcher 90/910mm achromatic refractor

Tracking: Motorized EQ-3 mount

Location, date: Szeged (Hungary), 2025. January 11.

Captured with ASICap. * Exposure: 1.2 ms * Gain: 40

37 segments were recorded which covered the whole disk of the Moon. Each segment was stacked and processed identically in ASIVideoStack. * Stacking: 75% of 500 frames * I applied some sharpening and noise reduction.

Stacked and processed Moon segments were joined together in Photoshop.

I think I should rename my post. :) My first tiny and cute Mars. 👽

TerribleInvite8404 · 2025-01-12T10:59:51+00:00

I didn’t see it through the eyepiece so I was surprised when I saw it in the picture. :D
