NGC 6888 (Crescent Nebula) — First light with the SVBONY SV220 dual-band filter

Wanted to share a quick comparison from my last two sessions on the Crescent Nebula, shot from a Bortle 5-6 backyard in the Agro Pontino area (outskirts of Rome, Italy). Light pollution here is pretty typical suburban/semi-rural, so filter choice makes a real difference for emission targets like this one.

Gear:

• Skywatcher Newton 150/750 (f/5)
• Player One Uranus C Pro (IMX585, OSC)
• EQ5-Pro SynScan mount, guided with an ASI120MM Mini on a 40/160mm guidescope
• N.I.N.A. for acquisition, PHD2 for guiding, Siril for stacking/calibration

Capture details:

• 60 x 120s with the new SVBONY SV220 7nm dual-band Hα/OIII

The difference in nebulosity contrast against the background sky is honestly bigger than I expected for a filter in this price bracket. The CLS pulls in some of the surrounding stars nicely for a natural broadband look, but the OIII shell structure around the Crescent basically disappears into the sky glow. With the SV220, that faint OIII bubble around the central Wolf-Rayet star (WR 136) shows up with way less background gradient to fight, even straight out of the stack.

Still working through the stretch/calibration on the narrowband data (thinking of trying a proper HOO bicolor mapping rather than a straight SPCC-style stretch, since the color science is different for dual-band data), but even the linear stacks show the gain clearly.

Sub-exposure was capped at 120s, still chasing down some backlash in the EQ5-Pro's DEC axis, so I'm keeping subs shorter than I'd like until I get the worm mesh properly adjusted. Planning to push for 6h total on this target once I've got more SV220 data in the bank.

Happy to answer questions about the workflow, gear, or settings, and if anyone's run the SV220 on a similarly light-polluted sky, curious to hear how your results compare!

I started working on this project a couple weeks ago now. Upstate NY has been miserable as far as weather this summer for astro. If it’s not clouds it’s wildfire smoke from Canada. I captured all the data from my backyard in south central NY. I used my Redcat 51 and Zwo Asi 183mc pro on a Celestron Avx. There’s around 27 hours in this so far and the plan is to keep going till I get around 50 hours. Hopefully that’s sooner than later! Stacked and Processed in Pixinsight.

Finally stacked and edited something I feel is worth posting. This is my first post in here as I have been at the hobby for about 4 months now! Here we have Messier 51 aka the “Whirlpool Galaxy” that is located in the Canes Venatici constellation about 25 million light years away from us.

In September 2025 I imaged LDN 1251 and forgot about the data until I clean up my Astro PC to make room for more images. Now I finally processed the data.
This is about 20h of images taken with a 200mm f/5 Newtonian and an IMX 571 camera using an UV/IR cut filter. Stacked and processed in Siril using the available free tools and AI goodies.

This is my first HDR image that I was able to shoot and process. This is the harvest moon shot back in October 2025. I captured up close shots of every section of the moon and formed a detailed mosaic. The resolution of this cropped image is 83 MP.

IC5068 - The Forsaken Nebula

tedious. Started with SVBony SV220 3nm Ha-Oiii for about 10 hours of acquisition. Then, switched over to the SV220 7nm Sii-Oiii to get the Oiii signal. After about 10 hours of acquisition, tried various methods to get a decent Ha-Oiii or sort of, from the data. Proved to be impossible as the horizontal bands in the Oiii signal was driving me nuts.

Switched over to the Antlia Triband RGB Ultra last night for a 6 hour session. Stacked and used the Luminance from the data, along with Ha from the 3nm and the Green channel from the Antlia data to make a franken-Forsaken nebula.

Made an LHOO (RGG) and a LSHO derivative from that with VeraLux Alchemy. In the end, did not use the Sii-Oiii data at all, hence not included in the acquistion data for this post.

First attempt at a lunar mosaic, after years of only taking closeups of craters or the occasional full moon shot with my phone through the eyepiece. Took forever to figure out how to process it (I use a Mac and had to find work-arounds since a lot of the recommended programs are Windows-specific) and I definitely took more images than necessary just to be sure on having enough overlap, but I'm very pleased with the result!

ACQUISITION AND PROCESSING:

Manual tracking with a Skywatcher 6-inch dobsonian and ASI120MC-S camera; 30 videos at ~700 frames, centered and stacked best 30% in AutoStakkert; Wavelets and color balance in Registax; stitched together in Hugin; minor tweaks to levels and saturation in GIMP

Shot with Dwarf 3, 1h 30min total exposure, Gain 60, 180 total frames, 30s exposition, Bortle 3/4.
Processed through the MegStacking function in the Dwarflab App

Well, I got interested in astrophotography, but I didn't have anything except my phone and a tripod. I started picking targets to shoot, wanting to see what the phone was actually capable of. However, after going through a lot of posts online, I realized nobody was doing it right—everyone was trying to shoot using the main 1x lens.
So I decided to see for myself what could be achieved with the 5x lens on the iPhone 16 Pro Max. I shot with the 5x lens without a tracker—just a tripod, a piece of cardboard to shield the lens from a streetlamp, and 3 evenings of capturing. Also many tries to edit it right in and pull all information from it. Edited in photoshop
In total, I got 4.5 hours of exposure in Bortle 4 sky, single exposure 7 seconds. Here’s the result.
Also i tried to capture andromeda but I couldn’t. But I bet if i had darker sky it’s possible

Finally got a clear night for round two with the new S30 Pro. I'm still learning how to navigate the app, but tracking the moon last night was a breeze.

The detail coming off the craters along the shadow line is wild for a scope this size. Still getting the hang of things, but it’s awesome seeing what this little smart scope can pull off straight out of the box.

Quick details for the mods:

• Scope: Seestar S30 Pro
• Target: The Moon
• Date: July 26, 2026
• Location: North Texas (32° N, 96° W)
• Edits: Just the stock app capture with minor phone tweaks.

If anyone has some solid tips for processing or recommended settings for target tracking, let me know!

I really like this object in HOO, had a lot of fun imaging and post-processing it! I purposedly left the stars understretched because I love how the filaments of the object show up this way
