Is THIS the DIMMEST nebula you can image? IFN!

What’s the dimmest nebula you can actually pull out with amateur gear? In this video, I take you along for my multi-week adventure trying to answer exactly that — by hunting down the Integrated Flux Nebula, the faintest cosmic cirrus drifting high above the Milky Way. My target? The Iris Nebula (NGC 7023) — a bright reflection nebula surrounded by a ghostly veil of IFN, plus the nearby Ghost Nebula drifting through the same dusty region. You’ll see me wrestle with cloudy nights, surprise wind gusts, a dawn cameo from Venus and the crescent Moon, and sand in literally everything during my first attempt at The Pinery Provincial Park. Not satisfied, I packed up my vintage Frankenstein rig — NIKKOR 300mm ED prime, homemade wedge, ASI294MC Pro — and eventually upgraded to the ASI2600MC Pro, chasing darker skies north to Torrance Barrens Dark-Sky Preserve, about 200 km from Toronto. Torrance Barrens is Canada’s first permanently designated Dark-Sky Preserve — a stretch of exposed rock and open sky that’s perfect for revealing these faint cirrus clouds we normally can’t see. In the end, I pulled out over an hour and a half of decent data — enough to show the Iris floating in its smoky halo of cosmic dust. It might not be an award-winning image, but it’s a reminder that there’s a whole hidden layer of structure in our skies, if you’re patient enough to chase it. Clear skies — and tell me in the comments: what’s the dimmest nebula YOU’VE ever captured? #Astrophotography #DeepSkyAstro #IrisNebula #IntegratedFluxNebula #IFN #WidefieldAstro #ASI2600MCPro #VintageLens #FrankensteinRig #TorranceBarrens #DarkSkyPreserve #BackyardAstro #DeepSkyImaging #Stargazing Equipment Overview: Telescope: Celestron NexStar 6SE (150mm SCT) Mount: Celestron SLT in Equatorial Wedge Mode Camera: ZWO ASI294MC Pro, ZWO ASI2600MC Pro Filter: UV/IR Cut Processing: Graxpert, Siril & GIMP *Well-Known IFN Targets* #### 1. *Polaris Flare (Ursa Minor)* Region near **Polaris**, the North Star. Wispy cirrus-like structures spanning several degrees. Great for ultra-widefield imaging. #### 2. *MBM 54–55 Complex (Pisces–Aries)* From the *Magnani, Blitz, and Mundy (MBM)* catalog. These are among the *closest molecular clouds* (\~100-200 light-years). Often imaged with Pisces/Aries star fields. #### 3. *LDN 1235 (Shark Nebula, Cepheus)* Part of a dusty filamentary IFN network. Located near **NGC 7023 (Iris Nebula)**. Can be captured with widefield lenses or 300mm setups. #### 4. *MBM 12 (Aries)* Near the star **29 Arietis**. Among the brightest IFN regions, sometimes visible in shorter exposures. Good intro target for imaging IFN. #### 5. *LDN 1251 and LBN 762 (Cepheus Flare Complex)* A large dusty region in **Cepheus**, overlapping with reflection and dark nebulae. Often shows up as a complex mix of dust and faint stars. --- *Advanced IFN Regions* #### 6. *South Galactic Cap Cirrus (SGCC)* A broad, dim region of galactic cirrus south of the galactic plane. Spans many degrees, perfect for mosaic projects. Imaged successfully by IRAS, Planck, and widefield amateurs. #### 7. *IFN near M81 and M82 (Ursa Major)* Famous because it **overlaps with the M81 Group**. Often shows faint tendrils of dust **surrounding or overlapping the galaxies**. Makes for a dramatic deep image. #### 8. *IFN near the Pleiades (M45, Taurus)* While the *main reflection nebulae* are well-known, faint IFN continues beyond. Widefield images often reveal extra structure not visible in typical M45 shots. #### 9. *IFN around NGC 1333 and LDN 1448 (Perseus)* Located in the **Perseus molecular cloud**. Dusty background around active star-forming regions. --- 📷 *Imaging Tips* Use a *fast lens or scope* (e.g., f/2 to f/4). Integrate for *many hours* (5+ ideally). *Dark skies* are essential (Bortle 2–3 or better). Use *light pollution filters* sparingly—some IFN is broadband and can be suppressed. Stretch carefully in post-processing to avoid over-amplifying noise.
