All Telescope Lenses in Fisch

There are currently five Telescope Lenses to collect: Deep Lens, Seasonal Lens, Experimental Lens, Moonlit Lens, and Stellar Lens. Each one has a different purpose, so the best choice depends on what you are trying to accomplish.
| Lens | How to Get | Astral Anomaly |
|---|---|---|
| Deep Lens | Craft with Astronomer Vega | Abyssal Alignment |
| Seasonal Lens | Craft with Astronomer Vega | Evershifting Eclipse |
| Experimental Lens | Craft with Astronomer Vega | Meteoric Outburst |
| Moonlit Lens | Craft with Astronomer Vega | Lunar Eclipse |
| Stellar Lens | Complete the Brayden quest or craft with Astronomer Vega | Celestial Congregation |
How Do Telescope Lenses Work in Fisch?

Telescope Lenses are special items that can be equipped through the Astronomer Vega NPC. Once you have the appropriate Lens, you can use it with the Telescope to activate its associated Astral Anomaly.
Each anomaly provides a different bonus that lasts for a whole night cycle. Moreover, you can switch between them, making the Telescope significantly more useful. This means you do not necessarily want to use the same Lens all the time.
Deep Lens
The Deep Lens is designed for those who want to focus on catching heavier fish. It is crafted by Astronomer Vega using three materials associated with the deeper areas of Fisch. Below, we’ve listed all materials and how to get them.
| Material | Rarity | Location | Bait |
|---|---|---|---|
| 1x Hardened Glass | Exotic | Abyssal Zenith – Astral Cavern | Magnet |
| 1x Abyssal Comb Jelly | Mythical | Abyssal Zenith – Astral Cavern (Use Rod of the Depths or appraise it) | — |
| 1x Abyssal Resin | Secret | Fish at Mushgrove Swamp (Use Rod of the Depths or appraise it) | — |
The Deep Lens activates Abyssal Alignment, which provides a +25% Catch Weight bonus. This makes it a strong option when your primary goal is to land heavier catches rather than maximize XP or mutation chances.
Seasonal Lens
The Seasonal Lens is centered around XP progression. Like the Deep Lens, it is crafted by Astronomer Vega, but collecting its ingredients requires you to travel through different areas and account for specific weather, seasons, and times. Below, we’ve listed all materials and how to get them.
| Material | Rarity | Location | Bait | Weather | Season | Time |
|---|---|---|---|---|---|---|
| 1x Seasonal Glass | Exotic | Astral Cavern – Everturn Forest | Magnet | None | None | None |
| 1x Floraseer Sturgeon/Glaciaseer Sturgeon/Solarseer Sturgeon/Umbraleaf Sturgeon | Mythical | Everturn Forest | Phantom Leech/Golden Shrimp Bait/Super Flakes/Night Shrimp | Clear or Rain | Spring/Winter/Summer/Autumn | Night |
| 1x Rotting Glass Diamond | — | Overgrowth Caves (Fish using Splitbranch Twig) | — | — | — | — |
The Seasonal Lens activates Evershifting Eclipse, granting +25% XP. Because of this, it is particularly useful when your priority is leveling rather than maximizing fish weight or hunting mutations.
Experimental Lens
The Experimental Lens takes a different approach from the previous two Lenses. Instead of directly improving your fish catches or XP, it enhances the rewards you receive from meteors. Below, we’ve listed all materials and how to get them.
| Material | Rarity | Location | Bait | Weather |
|---|---|---|---|---|
| 1x Quartz Glass | Exotic | Cryogenic Canal – Astral Cavern | Magnet | Any |
| 1x Chaotic Golden Trout | Rare | Cryogenic Canal – Astral Cavern (Fish using Duskwire) | — | — |
| 1x Fallen Resin | — | Mushgrove Swamp | — | — |
The Experimental Lens activates Meteoric Outburst, boosting the reward to 4 to 6 items per meteor. It also improves your chances of obtaining Gems. Therefore, this Lens is an excellent choice when you are specifically farming meteor rewards or looking for Gems.
Moonlit Lens
The Moonlit Lens is the mutation-focused Lens in the Telescope collection. Its crafting materials take you toward the colder regions of Fisch, while one of its key ingredients requires fishing under specific conditions. Below, we’ve listed all materials and how to get them.
| Material | Rarity | Location | Bait | Weather | Season | Time |
|---|---|---|---|---|---|---|
| 1x Frozen Glass | Exotic | Astral Cavern – Snowcap Island (Catch and appraise for the mutation) | Magnet | — | — | Night |
| 1x Aurora Boreal Man O’ War | Mythical | Boreal Hollow | Minnow | Rain | Winter | Night |
| 1x Frozen Resin | Secret | Mushgrove Swamp (Catch and appraise for the mutation) | — | — | — | — |
The Moonlit Lens activates Lunar Eclipse, giving you a 5% chance to obtain Aurora, Lunar, Celestial, and Nova Mutations. This makes it one of the interesting choices for those specifically completing quests with these mutations.
Stellar Lens
The Stellar Lens is different from the other four because you can either craft it from Astronomer Vega or complete the Brayden quest to get it. If you want it for free, you have to find Brayden inside the cabin at Boreal Pines, located around GPS (21626, 141, 4482).
After starting the investigation, you need to travel across Fisch and locate all six Broken Stars. They are scattered across several major locations, so below, we’ve listed all the Broken Star locations in Fisch.
| Broken Star Location | Coordinates |
|---|---|
| Terrapin Island | 124, 200, 1978 |
| Roslit Bay Volcano | -2001, 190, 389 |
| Mushgrove Swamp | 2519, 156, -921 |
| Ancient Isle | 6142, 391, 657 |
| Snowcap Island | 2840, 389, 2712 |
| Moosewood | 682.7, 252.4, 323 |
Once you collect all six Broken Stars, continue following the quest objectives to eventually obtain the Stellar Lens. Alternatively, you can craft it through Astronomer Vega, but you first need to collect three specific materials.
| Material | Location | Bait | Weather | Season | Time |
|---|---|---|---|---|---|
| 1x Starfall Glass | Astral Cavern – Boreal Pines | Magnet | Foggy | — | Night |
| 1x Celestial Aurora Gar | Astral Cavern – Boreal Pines | Minnow | Clear | Winter | Night |
| 1x Nova Resin | Mushgrove Swamp (Fish at using Cerulean Fang/Astraeus Serenade) | — | — | — | — |
Once you have obtained all the materials, you can use the Lens to activate Celestial Congregation, which provides a +25% Luck bonus, making it a useful choice for general fishing and improving your overall chances of catching valuable fish.
All Astral Anomaly Effects in Fisch

Once you have collected the Lenses, you can compare their effects to determine which one fits your current goal. Below, we’ve listed all the Astral Anomalies and their effects.
| Lens | Astral Anomaly | Effect |
|---|---|---|
| Stellar Lens | Celestial Congregation | +25% Luck |
| Deep Lens | Abyssal Alignment | +25% Catch Weight |
| Seasonal Lens | Evershifting Eclipse | +25% XP |
| Experimental Lens | Meteoric Outburst | 4 to 6 items per meteor + increased Gem odds |
| Moonlit Lens | Lunar Eclipse | 5% chance for Aurora, Lunar, Celestial, and Nova Mutations |
Tips for Collecting All Lenses in Fisch
Collecting every Lens is easier if you approach the materials systematically. Rather than trying to gather everything at random, first decide which Lens you want and write down its three required materials.
It is also worth combining your trips whenever possible. Since several recipes use materials from Mushgrove Swamp, you can collect the required Resin while working on another Lens instead of making repeated trips later.
Also, make sure to pay close attention to bait and fishing conditions. Several materials require specific baits, while some catches depend on weather, season, and nighttime conditions. Preparing the correct bait before traveling to the relevant area can save time.
