Supernova SN 2026kid in the Knife Edge Galaxy (NGC 5907) tonight through a Green filter. Current mag. is ~15.6 by a quick aperture photometry on the stack in Siril. Stay tuned for an LRGB image later. 8" F4 Newt + 585 Mono 47 x 60s G, 2026-04-26 21:37-22:29 EDT (UTC-4) #Astrophotography #SN2026kid

The Rosette Nebula (Caldwell 49) is always a majestic sight to behold - a bright patch of H II emission in Monoceros, next to the distinctive Orion stars. A collaboration of two ToupTek HOPE D60 + ATR2600C setups resulted in the following shot over just a few hours of clear skies. #Astrophotography

Simeis 147 (SNR G180.0-01.7), also known as the Spaghetti Nebula, is an expansive supernova remnant that spans the width of 6 Moons side by side on the border of Auriga and Taurus. I gave it spaghetti colours with a slight shift in the Ha hue. #Astronomy #Astrophotography

Live stacking enables us to quickly get an idea of what major structures will show on the final image. I use the "Folder Monitor Camera" in SharpCap, in which I can open the folder with NINA data and stack exposures up as they accumulate. It's only a matter of increasing SNR atp. #Astrophotography

The California Nebula Revisited in SHO with OSC Data - AstroBin
How far I’ve come since I began astrophotography last year! Revisiting the California Nebula this fall, I used two narrowband filters on an OSC to gather the SHO data needed for this colourful image.
011
WLR2678 @wlr2678.bsky.social · 01/11/2025
Same location, same sensor behaviour (IMX571 and IMX533), almost the same exposure time. Different scope, filters, processing tools and skills. This is my last photo of the nebula from Sept. 2024 in comparison.

The California Nebula (NGC 1499) is a large, rich patch of emission in Perseus, its trapezoidal shape resembling the State of California. The Ha, SII and OIII components reveal beautifully in narrowband filters, and an OSC camera was used to compose the SHO image below. #Astronomy #Astrophotography

The Coathanger (Collinder 399) is an interestingly shaped asterism in Vulpecula. A binocular can be used to observe it visually. Here is my broadband photo of the asterism and its surroundings at ~1.2h of integration from last night. #Astronomy #Astrophotography

Hello #CometLemmon, all the best on your journey! I captured the comet in this composite with a 40-year old vintage Minolta lens (MD 50mm f2). The foreground was shot at 17mm f1.8, all on a small MFT pocket camera. #Astronomy #Astrophotography

You can easily snap quick shots of #CometLemmon with the landscape now, through regular cameras or phones, as long as the weather cooperates. This was a 10s exposure last night at ISO400, taken with a M43 camera and 17 mm f/1.8 lens (FF equivalent of ~35 mm) near Lake Simcoe. #Astronomy

Right, I think there are many more options now, there used to be just the Askar and Altair ones, but now Optolong and SVBony are releasing their products too. This one I'm testing is a “Scorpio Astro” 7nm SII-OIII, it's not well known but seems to be doing its job properly haha

WLR2678 @wlr2678.bsky.social · 18/10/2025
If possible, try a SII-OIII filter in combination with Ha-OIII! I'm amazed at how much more vibrant it looks even with OSC data and no mono single channels to start with. DBXtract helped to produce the SHO channels in post using IMX571's response curve.

I did crop a little for this shot though, because of some rotation between the two filters

I think it's mostly because of my refractor's lens not being optically perfect, and I'm using a lesser corrected reducer with it (the 0.6x one), leading to more aberrations than its performance by design.

I love how easy it is to spot Polaris B even through small-ish refractors. In this 5-sec snapshot during polar alignment you can visually count the pixels to gauge separation from its bigger brother. ~10 pixels, which is exactly ~18-19" given a pixel scale of 1.85"/px😄 #Astronomy
