I Put My Old DSLR to the Ultimate Test (Spoiler: It Tried Its Best) | best beginner telescope camera

Modded Canon Rebel T1i vs ZWO ASI2600MC on the Veil Nebula through a RedCat 51 and SV220 dual-band ; a data-backed comparison with SNR per hour, QE context, and real workflow friction (NINA DSLR handshake fail → APT fallback). Same scope, same target, identical processing in Siril, and scale-matched crops so it’s apples-to-apples. Measured results (per-hour normalized, Siril ROI on linear stacks): • DSLR (T1i): SNR/hr R 4.47, G 3.84, B 2.57 • OSC (2600MC): SNR/hr R 14.00, G 12.41, B 7.32 • OSC ÷ DSLR: ~3× overall (QE ~30% vs ~80% suggests ~2.7×; cooling + low read noise + no amp glow + dual-band sky explains the rest). Capture • Scope: William Optics RedCat 51 (250 mm f/4.9) • Guide: UniGuide 32/120 + ASI290MC • Filter: SVBONY SV220 (H-alpha + OIII) on both cameras • Guiding (PHD2 via NINA): 2.0 s • RA 70% • DEC Resist-Switch 90% • MinMo 0.18 px • Dither 6–8 px, settle ≤0.6 px for 10–12 s • Integration: T1i 22×240 s (88 min), 2600MC 28×240 s (112 min) → SNR normalized to per hour Question: What should I test next | stock vs modded DSLR, or OSC vs mono with filters? #DeepSkyLab #Astrophotography #VeilNebula #ASI2600MC #CanonT1i #RedCat51 #NINA #PHD2 #Siril #SV220 #OSC #dslr
