Captured using a Nikon D5300 and s 140mm lens

28x exposures ranging from 5-8 seconds

Stacked in astro pixel processor

Processed in Pixinsight

My 5th time trying to image a seemingly easy target with something being off... This time I must have nudged the lens out of focus slightly and there was some dew forming on the lens that I hadn't noticed. This hobby sure has a steep learning curve!

Still, decided to not throw away the whole attempt and did a quick processing. It's about 45 minutes worth of 30 sec exposures at 500mm f6.3.

Feedback appreciated!

Took a 8min exposure with my Nikon D800 and my 50mm f/1.4 by night.

I find it quite interesting how the image looks almost like it's daytime, just with startrails in the background.

On our journey to shot the best images we can with our non ideal setup we collected more data on the heart nebula. Main problem with our setup is the distance of the sensor which is not perfect and results in bad star shapes in the corners. Stepping down to 2.8 and using BXT helps a lot. Combined with old data we gathered a total exposure time of 14 hours.

63 x30 sec tracked, 10 of each calibration frames. Stock Sony A6000, ISO 1600. 500mm f8 ish with a ttartisan lens.

Feedback appreciated!

73x30 sec of the Orion nebula, with a stock Sony a6000 and a ttartisan 500mm f6.3 on a StarAdventurer.

Lens was wide open, which introduced lots of aberrations on the brightest stars. Will try stopping down next time. Also, focus wasn't perfect and I had some dew issues.

No calibration frames, either, I was just testing the lens for the first time.

25 minute exposure of NGC 2264 taken with a seestar s50. Testing the new denoise function added in the most resent seestar firmware update.

No further post processing so colors seem to be a bit off as a result of the denoise feature, but otherwise an amazing result as most images from the seestar s50 contain a lot of RGB noise!

Shot with Vaonis Vespera II smart scope. 30 minutes of observation.

This is a first test to shoot NGC 7293 with a 135mm lens. Sadly we could only gather 15 min exposure time as the time frame for shooting this nebula is super short and we had a lot of clouds. Hopefully we have better conditions next year. But this test makes us hopeful to get a decent image with our equipment.

I recently discovered the Open Astro Tracker by OpenAstroTech. Does anyone have experience with it and can recommend it? I don't want to spend time and money for a product that maybe won't work, but I really like the idea of a self build tracker. I also like that it can be upgraded later by adding things like a autoguider

Because my camera is only ~1kg (2.2lbs) the small model is enough and I don't plan on upgrading anytime soon. If I can be sure it will work, its fine if it takes some time to print and assemble.

Also, can someone make a rough estimation of the price? On the website it is around 250€ for a complete kit, but I have a 3d printer and don't need the autoguider right now. For me that seems a little expensive for mostly 3d printed parts.

Or would the tolerances needed in the hinged mirror make the whole thing unusable?

I was looking at modern "smart telescopes" recently and noticed some are sideways and wondered if that would be possible for a normal hobby Newtonian telescope.

Possible upsides:

• no tripod needed for use
• mirror is light so smaller motors can be used for movement

Possible downsides:

• maybe mirror flatness?

EDIT/UPDATE: so i tryed it with a 75mm first surface mirror, it kinda worked, at least better than a normal mirror, but i wasnt able to get it as sharply focused as i like. I suspect the mirrior i use has micro ripples because its just 2mm thick and doesent look like its seen a polishen process....guess thats how far a budget of 25bucks gets ya

I'm thinking about an IoT Polar Aligner. The main idea is to use a Raspberry Pi W with the camera module to find and detect the North Star and display it on the mobile phone. The final goal is to connect it with servos so that it can automatically align itself. Does anyone know of a similar open source project?

Got another shot at C/2023 A3.

Southern Ohio, USA. Bortle 3. Exif data is in the image. Colored adjusted in Gimp. We actually saw zero meteors. I was quite disappointed until I got home and looked at the RAW files in Windows Photos Legacy. I found 8-9 meteors! Apparently RAW files have some magic going on.

Saw two shooting stars pop up while watching the comet last night, one of them showed up in the exposure I was taking at the time.
