- Findings:

1. 642nm IR Filter:
   - Great view of the Milky Way
   - Visible nebulae like the Lagoon Nebula
   - Nice view of stars
   - Reduces some glare from neighboring security cameras
   - Overall favorite filter
2. SVBONY 685nm IR Filter:
   - Cuts down more light pollution
   - Shows more of the Milky Way structure
   - Nebulae are cut off (Lagoon Nebula no longer visible)
   - Good view of stars
   - Allows a little more glare from neighboring cameras
   - Second favorite filter
3. 720nm IR Filter:
   - Shows structure of the Milky Way
   - Milky Way looks more transparent
   - Good visibility of stars
   - Nebulae are not visible
   - Too much glare from neighboring security cameras
4. Antlia Quadband Filter:
   - Incredibly soft Milky Way structure
   - Nebulae are visible
   - Stars are okay
   - Cuts all glare caused by security cameras
5. SV220 7nm Dual Band Filter (Ha and O-III):
   - Does not show the Milky Way structure
   - Shows all nebulae in the sky
   - Lagoon, Eagle, North America somewhat faint
   - Trunk Nebula very faint

- Recommendation:
- Stick to 642nm IR filter and 685nm IR filter for Milky Way
