I currently have a Canon T6 with a Opteka 500mm f8 lens ($87) that I use for lunar and solar photography. I recently purchased a full frame Canon EOS R and am thinking about getting a 800mm f11 Canon RF lens ($899). Will the quality on the new canon lens be significantly better than my Opteka lens? Is it worth the upgrade? Also, should I use my new full frame or my crop sensor (1.6 factor) to shoot? I want to get the best quality possible.
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 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.
