Rosa 'Red Gold' - AstroBin The first collab between two ToupTek HOPE D60 + ATR2600C setups. Two OSCs, dual narrowband filters, and just a few hours of clear-sky time over two nights.

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.

Spaghetti in Spaghetti Colours - AstroBin The expansive supernova remnant spanning across 3 degrees on the border between Auriga and Taurus, larger than the width of my APS-C camera sensor. This is around 15 hours of data through the HaOIII f...

Simeis 147 - The Spaghetti Nebula in modified HOO palette

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.

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.

Aurora resulting from a major solar storm in Nov. 2025, seen above Keswick in southern Ontario.

Cloud hole in the Windy satellite view

A break in the clouds magically appeared above some parts of southern #Ontario around midnight, so I was able to catch a quick glimpse of the #Aurora in time! 😍

My last photo of California Nebula in Sept. 2024.

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 revealing its beautiful details in the SHO palette.

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.

Collinder 399 is a coathanger-shaped asterism in the constellation Vulpecula.

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.

A composite photo of comet Lemmon and myself

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.

It's Astrospheric! Very useful to me

Astrospheric weather forecast

Th weather is looking really promising (a bit chilly here though) for southern Ontario and other areas around the Great Lakes starting Sunday! Find a place with good visibility of the western horizon and go meet #CometLemmon due west after sunset!😃

Comet Lemmon seen above the clouds at Lake Simcoe

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.

It's so tiny!

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

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

Basically the same as your California Nebula setup haha

Thanks! This is the FMA180 + ATR2600C, so APS-C on a 180 mm fl mini scope🙂

NGC7822 and Sh 2-170 forming a question mark shape in the constellation Cepheus

NGC7822 and Sh 2-170 are two emission regions in Cepheus, that form a shape similar to a question mark. Using two dual band filters (6 nm Ha-OIII and 7 nm SII-OIII) with an OSC camera, I was able to produce a colourful composite of the area in true SHO palette🙂
