Astrophotography is the art of capturing the unseen, of travelling back in time.

-
Pleiades, M45
imaging info coming soon
-
M81, M82, NGC 2976, NGC3077
This has great sentimental value as it was my fist ever picture taken with the Dwarf2 smart telescope. I remember being next to a train station so there was a lot more light pollution than Bortle 6. Note the image artifacts in the corners caused by field rotation as it is an AltAzimuth telescope. 4 galaxies in one picture!
Imaging info: 51x15 secs, 80 gain, binned (lower resolution). -
Sun (D2)
Taken by the Dwarf 2 clamped to my balcony while I was having a beer (alcohol-free). Setup time was only 2 minutes. Great for spur of the moment photography . Imaging info: Telephoto lens, single image 1/100 sec, White balance daylight., ND1,000,000 filters over both lenses. The filters come with the Deluxe pack and are highly recommended.
-
Moon (D2)
A clean shot, directly imported from Dwarf 2, clamped to a balcony rail.
-
Comet 12P/Pons-Brooks (D2)
Direct from the D2. This is amazing for the fact that it was taken from a floodlit sports ground car park The Dwarf 2 had to fight through floodlights as well as Bortle 6 light pollution.
-
Horsehead & Flame Nebula (D2)
Direct from D2. Another amazing shot by the Dwarf 2 taken from a floodlit school playground in Bortle 6 conditions.
-
M33 Triangulum Galaxy (D2)
Direct from the Dwarf 2. This was an experiment just to see if it could be done. The D2 was clamped to a balcony so there is field rotation with some stacking artifacts. A great attempt though; the D2 didn’t let me down.
-
M45 Pleiades (D2)
A rough capture and edit (color is not balanced) of 200 or so 15 second images from the Dwarf 2. Note the heavy field rotation in the bottom right corner as it was very high in the sky.
-
M13 Hercules Cluster (D2)
Taken with Dwarf 2 from my balcony. I clamped it to a rail and fired away.
Imaging Info: 828x10s, Gain80, IR Cut. No Binning.

More about my equipment choices (why I don’t have big scopes).
I live in a (very) small apartment in a Bortle 6 zone, close to an airport so I often need to travel by car to a darker site. Everything needs to be very portable and consume less than 1 sq. m floorspace when stored.
Filters
ZWO Duo Band 1.25”
Used for Dwarf 2 Smart Telescope.
SVBony UV/IR cut 1.25“
Used for visual and Dwarf 2 Smart Telescope
SVBony SV128 Variable Filter 1.25”
For moon observation/photography when the moon is too bright.
SVBony UV/IR cut 2”
Used for Galaxy photography on Big and Widefield Rigs to reduce star bloat (stars appearing overly large due to accumulated UV/IR captured during long exposures..
SVBony SV220 Astro Dual Narrowband 7nm 2”
Used for Nebula photography to reduce light pollution and enhance nebulosity.
The filter allows OIII (500.7nm) and H-Alpha (656.3nm) nebula emission lines to be highly transparent, strongly isolates
the nebulae's emissions into H-Alpha (red) and OIII (green-blue), and drastically reduces the effect of light pollution.
SVBony CLS Filter EOS: Used for astrophotography on Canon EOS 600D DSLR.
Altair QuadBand OSC CCD 2" Filter: For tackling moderate light pollution with skyglow, typically found in suburbs. It combines Sii AND Ha into a red zone, and H-beta + Oiii into a green/blue zone. This is typically used with color cameras.

Siril - Free. Great all-rounder, fast stacking and good processing. Even better with the StarNet plugin.
AffinityPhoto 2 - Cheaper than PhotoShop. Can perform astrophotography stacking and some processing.
Topaz PhotoAI - Use minimally for DSO and never for planetary imaging as it can introduce false artifacts with poor settings.
