1. PRODUCT DESCRIPTION
Premium Baader 1.25" LRGB filter set for astrophotography with monochrome CCD and CMOS astronomy cameras
Precisely engineered passbands for superb color separation and contrast
Designed to pass critical wavelengths from nebulae and stars while rejecting light pollution from some terrestrial sources
UV/IR-cut Luminance filter rejects out-of-band light for pinpoint star images
Individually-coated filters prevent degradation from moisture
Hard coated for easy cleaning and long life
Baader 1.25" RGB Filter Set with UV/IR Cut L-Filter - Set of 4 filters. Baader item # FLRGB-1 or 2458472.
Overview
The premium filter LRGB filter set from Baader Planetarium is ideal for use with monochrome CCD and CMOS cameras for high-quality astrophotography through a telescope with high contrast and accurate color rendition in emission, reflection, and planetary nebulae, star clusters, and planets.
This filter set includes precisely engineered RGB color filters and a UV/IR-cut L (luminance) filter. Each filter is mounted in a precisely constructed 1.25” filter cell and hard coated for long life, even in demanding environmental conditions.
Superior Optical and Spectral Performance
Baader partnered with a leading optical thin-film coating provider to design and deposit multi-layer optical coatings that provide nearly ideal RGB transmission bands. The filters provide high light transmission over each passband and sharp cutoff outside of each band to maintain high contrast and color separation.
Individually, the Blue and Green filters pass light at the discrete wavelengths of H-beta (486nm) and OIII (501nm), respectively, but they also overlap to transmit proportionately more light from the important OIII band which is important in many nebulae.
The Green and Red filters in this set have a slight gap between their passbands to help reject undesirable emissions at 580nm from common mercury and sodium street lamps. This results in excellent color balance and rendition as well as high contrast and image sharpness, even in relatively light-polluted sky. The Red filter also fully transmits light from SII emission at 672nm.
The luminance filter, which transmits from 400nm to 700nm, also suppresses transmission of unwanted light outside of the visible band where the camera sensor is still sensitive (from 300nm-400nm and 700nm-1150nm) to ensure razor sharp star images. Many budget filter sets do not provide this degree of out-of-band rejection.
The Baader LRGB filter set also includes:
Homogeneous glass substrates that are parfocal and precision-polished to ¼-wave
Hard-coating of each individual filter substrate
Balanced RGB transmission to enable 1:1:1 exposure time for most telescope/camera systems
Maximized color contrast and transmission for each RGB channel
Virtual elimination of halos, reflections, and ghosting for professional quality astrophotos
Mechanical Design and Processing for Long Life
Unlike many budget filters, Baader Planetarium filters are not “biscuit cut” out of larger plates of glass, a process that causes micro-cracks around the filter edges. These cracks can attract moisture between the glass substrate and coating layers via capillary action which causes premature aging and degradation. By contrast, each Baader filter is individually coated to have sealed edges which prevent the penetration of moisture, even in very humid conditions.
Baader filters are tested repeatedly to comply with MIL-specifications. One common process is to boil the test specimen for one hour in salt water to induced damage. Unlike budget filters cut from larger plates, Baader filters remained completely intact during this rigorous environmental testing.
All Baader filters also include a hard, ion-beam-deposited scratch-resistant coating that makes routine cleaning easy and safe. These filters are truly made for a lifetime of serious astrophotography, and they will produce spectacular images with nearly any telescope.
Agena Note:
Please note that the filters in this set do not feature a female thread. Hence, you cannot stack additional 1.25" filters on to these items.
Note:
Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.

3. US SHIPPING
Delivery Time:
Most orders ship within 1 business day of receiving payment. First Class shipments will take 3-5 days to arrive after we ship it. Priority Mail shipments will take 2-3 days. However, these delivery times are NOT guaranteed by the USPS. Delays of up to 2 weeks can occur in about 5% of the shipments.

4. INTERNATIONAL ORDERING / SHIPPING
Shipping Cost:
Click on the "Shipping and Payments" tab above and select your country to see your shipping choices and cost. If you need a shipping cost estimate for multiple items, please contact us.
Delivery Time:
1) USPS First Class International:
Delivery takes about 3-4 weeks after we ship your package.
This can frequently take 4-6 weeks or more for several countries (8 weeks for Italy, Argentina, and South Africa; 8-12 weeks for Brazil)
.
THERE IS NO TRACKING FOR FIRST CLASS SHIPMENTS. The information shown in your eBay account is just a customs form number - it is NOT a tracking number as incorrectly indicated by eBay.
Once your package ships, we can do nothing but wait until your package arrives. Please do not become impatient and contact us in 2-3 weeks if your package has not arrived. If you don't receive the package in 6 weeks, contact us and we will work with you to resolve the issue. If you don't want to take the risk of this delay, then DO NOT USE First Class mail - use Priority or Express shipping instead.
(2) USPS Priority Mail International:
Delivery takes 1 - 2 weeks after we ship your package. This can sometimes take 3-4 weeks to several countries. The USPS provides some basic tracking information for Priority shipping.
(3) USPS Express Mail International:
Delivery usually takes 5-10 business days after we ship your package. You will receive a tracking number with which you can track your shipment from USPS.com. Note: If you use this option, you must send us your phone number when you check-out or else your shipment will be delayed. This is required for international postal forms.
Again, these delivery times are NOT guaranteed by the US Postal Service. The most common reason for delays is slow customs inspection and clearance in your country, and can be very long, even for Express mail packages. Upon shipping your order, delivery delays are beyond our control, so do not leave us negative feedback or file a Paypal claim if your package is delayed. Delays are quite common but losses are very rare, so your patience/cooperation will be greatly appreciated.
Customs and Duties:
You are responsible for any duties and taxes that may be levied in your country. These are not included in the item price or shipping cost. We have no control over these charges and cannot predict what they may be or if they will be levied upon delivery. Customs policies vary widely from country to country (Some countries such as UK are strict about imposing hefty customs duties). It is your responsibility to check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Customs fees are normally charged by the delivery company or your country's postal service, or collected when you pick the item up. These fees are NOT additional shipping charges.

Shipping fees are non-refundable (for items with free or discounted fixed shipping, the actual outbound S&H cost we incurred will be deducted) and you are responsible for all return shipping costs. Please contact us first before returning an item.
