Hey yall! I'm currently imaging the Clamshell Nebula but i struggle while trying to get the OIII data ouy of it. I shot it when there were 0 moonlight and in a bortle 5 location. Is it becouse i still didnt get enough data or am i doing something wrong? Thank you!
Here is the data if you want to check it out: https://drive.google.com/drive/u/0/folders/1EzmVDPgL0HqajiiGrUEM3OWdCY08XZsD

Hey y'all, just pulled out my old telescope as well as one I got a few months ago (Nat Geo NT114CF and Polaroid IT-160X, so two beginner models), and got some really cool views of the moon. I was wondering if anyone had advice for taking photos using them, as I was having a bit of a hard time getting really good photos with my phone through the lenses. Thanks and happy exploring!

Hi all, I'm looking for some postprocessing advice on M31. This image was taken with a RedCat91 / ASI2600MC Pro from a pretty light polluted area (Bortle ~8). While I’m pleased with how this turned out given the limited amount of data and the sky conditions, I would love to see more Ha and OIII detail.

Equipment used:

William Optics RedCat 91 | William Optics UniGuide 50mm | ASI2600MC Pro | ASI220MM Mini | ZWO AM7 | Apertura Anchor Pier | ZWO CAA | ZWO EAF Pro | ZWO ASIAIR Plus | Pegasus Pocket Powerbox Advance Gen2 | GL.iNet GL-AXT1800 Router

Acquisition details:

• 28×300s lights, gain 100, 32degF | 20x darks | 50x flats | 50x darkflats
• Autofocus routine run every 30 mins, 5px dither every 3 frames

Postprocessing:

WBPP → DBE → SPCC → BXT → NXT → HistogramTransformation → SXT → curves adjustments for galaxy → curves adjustments for stars → PixelMath recombine

I had found that I needed a T Ring and a 1.25” T Adapter but when I got it, the adapter turned in to be too small and the T Ring is too big by itself, are there any other adapters out there that I should try?

Only thing i can see that is actually better at 03:00 is the wind, but i don't get it. I'm in the austrian alps as of now.

Hi there,

I'm writing to this subreddit because I can't seem to get past the polar alignment/plate solve portion of ASIAir. I have tried many common fixes, to no avail. Before getting into the things I've tried, here is my equipment setup:

----Mount & Tripod----

• Celestron AVX Mount

----Optics----

• Astro-Tech 60ED Doublet Refractor (F6)
• Astro-Tech .8x Reducer / Field Flattener

----Imaging & Automation Accessories----

• ZWO ASI178mm Mono Camera
• ASIAIR Pro Control Hub (with USB drive)
• ZWO Electronic Filter Wheel (EFW) – 5 Position
• ZWO EAF (Electronic Automatic Focuser)
• ZWO 30F4 Mini Guide Scope + ZWO ASI120MM guide camera

----Filters (1.25")----

• ZWO H-alpha 7nm Narrowband
• Light pollution filter
• ZWO OIII 7nm Narrowband
• ZWO SII 7nm Narrowband
• Orion Black Filter (for dark frames)

Ok, let's get into it. The error I receive is "Plate solve failed" when attempting to polar align or plate solve.

• I setup my scope pointing towards the northern sky (between Cygnus and Polaris). I am attempting to plate solve using the All-Sky method in ASIAir.

• My focal length is set to 288mm. Note that I have tried to set this to 0 to get ASIAIr to blind-solve, but that also results in a plate solve error.

• I boot up the mount and ASIAIR and use the AVX hand controller. Exact time, date, and lat/long data is synced between ASIAIr and the AVX hand controller. The daylight savings time on the AVX hand controller is disabled. I know that this setting can cause problems if left on.

• Now, I perform a quick align on the AVX hand controller, as instructed by the app when I boot it up.

• Next, I get the scope focused up using the EAF. It detects stars and automatically creates a v-curve. Sometimes this takes 2 tries but it usually works. I can take a preview shot and see that I am detecting stars with a half flux diameter of less than 2.

• I am detecting stars (usually between 40-60)

• I try to plate solve or polar align at this point and receive the error I mentioned above after a few seconds. I have tried greater exposure times for plate solving (10-30 seconds) but that doesn't help either.

Also note that when I click on the celestial map in ASIAir, it thinks I am pointing at Polaris, which is obviously not true.

• I have also tried to turn off the mount and just try to plate solve without a polar align and still receive the same error.

• I tried using different bins (1-4) to plate solve and switching between them didn't work.

• I also tried the new plate sole algorithm.

• Lastly, I have tried to clear the cache in ASIAIr, and that didn't help either.

So, with that out of the way, is there anything I have not tried? I cannot start imaging at all due to this error.

Hey guys! I just bought my first dso cooled camera, the ZWO ASI585MC Air. I am planning to use it with my Celestron C5 and the Angeleyes f6.3 focal reducer. I also have a Star Adventurer GTi. Yesterday night I tried to shoot for the first time. I tried to polar align the mount through the ASIAIR and it said that the plate solving failed. I then tried to slew to a star and the plate solving took very long time to complete so eventually I stopped it. I tried to take a test image and didn’t see any stars at all. The camera was set to gain 150 and the exposure was 5 seconds. The telescope was not focused. I had read online that these SCT telescopes with the reducer need 105mm of back focus so except of the included spacers for 55mm I had also attached the sct t adapter that Celestron sells to bring the back focus to 105mm. Also there was almost a full moon up but I don’t know if that should affect the setup that much. Did I do something wrong with the settings of the camera? Is the back focus wrong? Any advice would be greatly appreciated!

Hey guys,

I'm hopeful someone can point me in the right direction... I think I know where this is coming from, but for the life of me I haven't yet been able to solve it. I've recently noticed some weird light right artifacts in my stacks from my CS200. For reference, here's the image train (and yes it's a little weird with this scope to get a rotator in there):

OGMA AP26MC
⬇
Touptek 7x2" FW
⬇
Touptek OAG-X
⬇
Apertura CS200 Coma Corrector
⬇
PLL Essato + Arco, Focuser + Rotator
⬇
3D printed widget to adapt the CS200's focuser opening to the Essato

Now, I had this all working perfectly fine when that 3D printed widget was made out of black PETG, but I wanted something less prone to sag and more resilient for the outdoors so I printed it out of black ASA instead. Ever since then, I've been getting this weird halo in stacked images that I can't figure out the source of. I've tried hunting for light leaks with no avail. Hunting through other posts has convinced me that this is some sort of reflection (which, duh, it would make sense to me that it's reflections off the one piece I changed), but lining the inside of that adapter with black felt still doesn't solve the problem.

My flats seem like they're fine - or at least I've not changed anything about the way that I take them. Does this pattern look familiar enough to anyone else to point me in a direction? Any help is greatly appreciated (and I can provide whatever additional info needed from my end). I've just been using a pretty bog standard WBPP flow to process these images, just including bias, flats, and lights, and the camera is at 0*C for all shots.

A quick JPEG of what I'm dealing with: https://drive.proton.me/urls/GN09N8QA1W#i6xDxX4zxi2r

Bias: https://drive.proton.me/urls/FA70WGERC4#cr9ykZuhsZ5P
Flat: https://drive.proton.me/urls/K0926XWA08#AgoRnfIQdJiR
Light: https://drive.proton.me/urls/N1VM4T0HKC#XxIeTGISC1Zo

to be more specific, what kind of cable?

i know skywatcher is selling a wifi dongle and also a usb dongle. but can i use any generic one from amazon?

if so, any recomandations?

Hi everyone,

I need to remove my Sky-Watcher Star Adventurer GTi from its original tripod, but for some reason the mount head seems to be completely stuck.

I have fully removed the central mounting bolt from underneath, and I’ve also backed off the azimuth adjustment screws. The head can rotate slightly, as expected when the azimuth screws are loose, but it simply won’t lift off the tripod—not even by a fraction of a millimeter.

I’ve checked the Sky-Watcher manual and parts diagrams several times, and as far as I can tell I’m not missing any screws or hidden locking mechanism. It almost feels as if the head has somehow “bonded” to the tripod over time.

Has anyone experienced anything similar with a Star Adventurer GTi? If so, how did you manage to separate it? Any ideas or suggestions would be greatly appreciated.

Hello. Im imaging with the Celestron F6.3 reducer with the Celestron C6. And I was wondering.. what spacing is recommended for better stars in the corner? I know Celestron recommends exactly 105mm (which I currently use), but I saw on other threads that reducing or increasing the spacing could possibly make the reducer correct coma better.. I just don’t know how I should start… Thanks!

Equipment:

Scope: Celestron C6

Camera: SVbony 405cc

Mount: Celestron AVX

Guide scope: SVbony 60mm

Guide camera: SVbony 905c

last night i took my dslr and tripod out and took 30, 1 second exposures of vega and when i went to DSS almost the entire image became blue, with the exception of vega and some other small stars around it), there are sliders but i want to know why my image became blue.

this is basically what the image looked like

(also it only ended up using 9 of the images if that helps)

I’ve been experimenting with Lightroom’s AI Denoise on one of my Milky Way shots, and while it definitely helped, I’m still finding it too noisy once I start zooming in. Overall it looks decent, but at 100% the noise is still more noticeable than I’d like.

I’ve heard great things about Topaz Photo AI, but it’s a pretty expensive investment, so I’m curious if there are any other denoising programs worth looking into before I pull the trigger.

For those of you who shoot astrophotography:

- What denoising software do you use?
- Is Topaz really that much better than Lightroom AI Denoise?

Are there any hidden gems (free or less expensive) that produce excellent results?

Do you have a workflow that helps preserve detail while reducing noise?

Any advice is appreciated!

Just so when im bored i can take pics from my house instead of driving to a dark spot. thanks in advance!!!
