The SVBONY SV227 SHO Narrowband Filter Set (W9187A) includes three 5nm narrowband filters — H-Alpha, O-III, and S-II — the complete trio for creating iconic SHO Hubble palette images of nebulae like the Pillars of Creation, Eagle Nebula, and Rosette Nebula. 5nm bandwidth strikes a useful balance between light throughput and light pollution rejection — making this a practical entry into three-channel narrowband astrophotography without breaking the budget. Fits standard 1.25-inch filter threads.

The SVBONY SV231 Fringe Killer Filter (W9186B) selectively suppresses the purple and blue halos that achromatic doublets produce at high contrast edges — improving color balance, contrast, and sharpness on the Moon, planets, and double stars. Multi-coated optical glass keeps light loss minimal. The 2-inch format threads onto standard 2\" eyepieces and diagonals; an M48×0.75 thread allows direct connection to camera adapters.\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;margin-top:24px;font-size:14px;line-height:1.5;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\" style=\"text-align:left;padding:10px 14px;background:#f7f7f7;border-bottom:2px solid #ddd;font-size:15px;font-weight:600;\"\u003eSpecifications — SV231 Fringe Killer 2\" (W9186B)\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;font-weight:600;color:#444;width:44%;\"\u003eFilter Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;\"\u003e2\" (M48×0.75)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;font-weight:600;color:#444;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;\"\u003eFringe killer \/ minus-violet color correction\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;font-weight:600;color:#444;\"\u003eBest For\u003c\/td\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;\"\u003eAchromatic refractors; lunar, planetary, double-star observing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;font-weight:600;color:#444;\"\u003eCoatings\u003c\/td\u003e\n\u003ctd style=\"padding:8px 14px;border-bottom:1px solid #efefef;\"\u003eMulti-coated optical glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 14px;font-weight:600;color:#444;\"\u003eWhat's in the Box\u003c\/td\u003e\n\u003ctd style=\"padding:8px 14px;\"\u003eSVBONY SV231 2\" Fringe Killer Filter (W9186B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Svbony","offers":[{"title":"Default Title","offer_id":44633363251234,"sku":"W9186B","price":56.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/6968\/5282\/files\/SVBONY_SV231_Fringe_Killer_Color_Correction_Filter_2_W9186B.jpg?v=1772884589"},{"product_id":"svbony-sv226-m54-filter-drawer-for-2-and-1-25-filters-w9184c","title":"SVBONY SV226 M54 Filter Drawer for 2\" and 1.25\" Filters — Easy Filter Swap for Astrophotography Setups | Telescope Wolves","description":"\u003cp\u003eSwap filters without dismantling your imaging train.
