Hi everyone. Thanks for looking. I know we're inundated with Mars pictures at the moment but I've not seen buckets of time-lapse and this marks a significant personal best for me so I really wanted to share it. I've not had seeing this good for a long time, especially with a planet this high above the horizon (I'm looking at you Jupiter & Saturn.....).
Only 12 frames spread across ~1 hour, but nice to see some movement. One single still as a bonus too
Edit to add acquisition & processing:
Skywatcher Skyliner 200P reflector (off my dobsonian), 1200 mm, unbranded 3x barlow for 3600 focal length, f/18 Skywatcher NEQ6 Pro mount ZWO ASI120MC-S - gain 33, 20 ms exposure, 2000 frames per video
Each video recorded with 5 minute spacing. 12 recorded in total. Stacked in Autostakkert 3, best 30% of frames. Wavelets, colour balance, and tweaks in Registax 6. GIF assembled in Photoshop with a few final contrast and levels tweaks.
I'm Jonny and I live in Farnborough in Hampshire, UK.
My friend and I are taking our first baby-steps into night sky photography so I'm here for all the help I can get.
We're just starting out so our equipment is very basic, but I'm sure the more we get into this the more we will upgrade over time.
Currently our set up consists of:
Home-made Motorised Barn Door Tracker (my friend is an engineer)
Canon 1100D with an 18-55mm Lens
Laptop with BackyardEOS
We took everything out for it's first test-drive last week and the tracker works really well. Even on very long exposures the stars remain as points and not trails so we were really pleased with how it performed.
I've attached what was probably our most successful picture of the evening. It' not amazing, but it's a start.
I would really love to get some photos of the Milky Way and I'm hoping you all could suggest some settings to use, imaging techniques to try out and equipment upgrades? We're on a bit of a budget but we have photographer friends from whom we can beg and borrow equipment.
Looking forward to chatting with you all in time.
I reside in the central great plains of the United States, and recently our west coast has been set on fire by rioters and arsonists due to civil unrest.
The smoke from these residential homes and forests burning, is delivered high into the atmosphere where it hit the jetstream and has traveled well over 1000 miles to blanket my sky.
While i can still take some images, it has greatly reduced my session quality at 393nm. Naturally the smoke properties absorbes or reflects much of this wavelength. The sun is very white in the sky in fact, white as a cotton ball in some areas.
However, i am vigilant in my attempt to capture something out of the new active region. Please be patient while this data is processed.
First we have a look here at the paris meudon bass2000 spectroheliograph , which records its daily calcium k3 core full disc. I have added an arrow to the tiny area that my scope is focused on at about 2400mm..
Full image disc citing goes to paris meudon observatory, with corresponding link to the wonderful and most vital French institution. http://bass2000.obspm.fr/home.php
Next from my telescope, operting with an explore scientific Firstlight 127mm x 1200mm achromat. In the focuser is a Skybender tilt module with some calcium filters supplied by Apollo Lasky. I am using a Meade 2x telenegative barlow in the eyepiece of the skybender, and a basler aca1920-155um cmos camera for recording.
Look at those calcium ribbon's! This is a rare capture, seldom seen since cycle 24, a decade ago.
Newbie to the forum but I just wanted to share some shots with you that I managed to get over the weekend. Got the Milky Way and even a few of NEOWISE which was amazing to witness 😊
Milky Way - 5 x 20 seconds stacked (not tracked), 11mm, F/2.8, ISO 800
NEOWISE Landscape shot - Single exposure, 8 seconds, 16mm, F/2.8, ISO 800
NEOWISE Stack 1 - 2 x 10 seconds, 16mm, F/2.8, ISO 800
NEOWISE Stack 2 - 2 x 13 seconds, 55mm, F/5.6, ISO 1600
For a first real attempt, I'm pretty pleased with them but obviously, I have a lot more to learn!
Last week I recorded a calcium limb surge. Later that night I discovered another user in the world on astrobin (Warren Spreng) who had captured the same event in hydrogen alpha at nearly the same focal length. The was an incredibly rare occurrence.
I merged our two captures together, and this is the result. Red is the hydrogen alpha data, blue is the calcium data.
I do believe this has a "one in a billion" capture odds, and few(if any) amateurs have ever been able to share and merge this type of time-lapse data.
