Msa Altair 4x Filters

[Charise Zelnick]

Now you can capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow. Capture more data in less time, and open up your imaging time window - even into the summer months.

Altair Tri-Band and Quad Band filters work by isolating the primary nebulae emission zones in the red and blue/green wavelengths, and separating them into two main "zones" with a wide separation for easy capture with a colour camera - all in one exposure! Not only is capture very convenient, but processing is easy too, thanks to the wide separation of the green/blue and red "zones". Light pollution control is extremely effective and LED light is also significantly reduced, thanks to the effects of Rayleigh scattering.

Sensitive OSC or "One Shot Colour" CMOS cameras like the Altair Hypercam 183C capture these wavelengths very efficiently, and allow them through the Bayer matrix. The filters also work with DSLRs (APS-C sensor size modified cameras are best, but normal ones will also work). When you have the complete stack of exposures, processing is relatively easy because of the large separation in colour. You can also use the Quad band and Tri-Band filters as a "super luminance filter" for imaging nebulae with Mono cameras.

Use this functionality to trim the records displayed on a table so that you can work with only the data that you need. Columns that have been filtered show the filter icon to the left of the column name.

In the example below, the results of the filter defined by the image in Step 3 are displayed. Here, the original table contains the values "Accounting," "Data Processing," and "Marketing" in the Department field.

Between - This filter operator allows you to define numeric ranges; when this operator is selected, you must also select one from each of two sets of operators (i.e., greater than/greater than or equal to and less than/less than or equal to) to identify the range to filter for.

Between - This filter operator allows you to define date/time ranges; when this operator is selected, you must also select one from each of two sets of operators (i.e., greater than/greater than or equal to and less than/less than or equal to) to identify the range to filter for.

You can specify calendar and/or clock values when creating date/time filters. To do so, click on the drop-down buttons provided beside the date/time fields in the Apply (Date/Time) Filter dialog and then click Calendar or Clock.

All of the filters applied to a table may be discarded simultaneously by right-clicking on any column in the filtered table and then selecting Discard All Filters from the options that display. Note that this operation only displays when at least one filter has been applied to the table.

Altair Monarch is a leading data preparation solution and offers a collection of filtering techniques that can dramatically simplify and enhance the data preparation process. This blog post explores all the filtering techniques available in Altair Monarch, providing insights into their applications and benefits.

Data filtering in Altair Monarch is about selectively narrowing down the data based on specific criteria. This process helps in focusing on information that is relevant to the analysis task at hand. Whether you are dealing with financial records, customer data, or operational metrics, Monarch provides an intuitive and powerful way to manage and manipulate your data.

For this post, we will show examples using a generic dataset that would be Marketing information from a banking institution and using Altair Monarch Data Prep Studio. The original dataset shows 4,521 entries.

The advanced tab on this menu allows you to change a few additional settings like ignoring duplicate entries, selecting specific rows to perform your filter, limiting the number of returned entries and a few others.

My Compound Filter menu has an expression box that was similar to what we saw with the Formula-Based filter. Again, if you know the syntax you can manually type out the compound in this box, or you can add/remove filters from the menus above. For this example, I want to return entries that have a balance on their loan AND are married (Fig 6).

All created filters can be saved and used for future data manipulation needs which makes for a quicker workflow, especially for those that reuse various data criteria constantly throughout their process. Filters are just one of the many simple, yet powerful features for preparing data using Altair Monarch. To learn more you can visit our product page for Altair Monarch or contact us directly.

Altair TriBand is the new trend in light pollution filters for deep-sky imaging of emission nebulae with colour CMOS, CCD, and DSLR cameras. Altair V2 Filter Technology produces even better blocking of unwanted wavelengths, higher transmission, and no halos. The result is a better signal to noise ratio for imaging emission nebulae with a DSLR or CMOS Astro camera.

The passband not only makes the TriBand V2 compatible with fast focal ratio lenses and telescopes, but also allows visual use with a medium size telescope in urban locations. Brighter emission nebulae can be observed in urban conditions with a darker background.

This is the new TriBand V2 Coating technology which includes:

Anti-Halo coating on both surfaces to reduce reflection artefacts from reducers and camera lenses.

Increased blocking of UV, IR and unwanted visual range wavelengths. UV OD7 (T0.00001%) Visual OD5 (T0.001%) and IR OD4 (T0.01%) for the ultimate in skyglow blocking. This is an order of magnitude better than foreign filters.

Higher transmission % of desired wavelengths Ttop 93% (Average 5% higher transmission of target wavelengths than V1). In general a 5% gain on foreign filters.

Ha at 14nm and Oiii at 34nm FWHM for with less tail-off to reduce unwanted light pollution, whilst keeping transmission high compared to the V1.

It's even compatible with fast scopes, like Altair refractors which operate at F4.8 with reducers.

Includes UVIR blocking for both modified and un-modified DSLR cameras, plus an anti-reflection coating to reduce halos as much as possible.

Narrowband Bi-Colour imaging is a growing new trend in astrophotography, especially popular in light polluted areas, or for imaging in rural areas in moonlight.

Now you can capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow. Capture more data in less time, and open up your imaging time window - even into the summer months.

Altair TriBand light pollution filters work by isolating the primary nebulae emission zones in the red and blue/green wavelengths, and separating them into two main "zones" with a wide separation for easy capture with a colour camera - all in one exposure! Not only is capture very convenient, but processing is easy too, thanks to the wide separation of the green/blue and red "zones". Light pollution control is extremely effective and LED light is also significantly reduced, thanks to the effects of Rayleigh scattering.

Sensitive OSC or "One Shot Colour" CMOS cameras like the #Hypercam183C capture these wavelengths very efficiently, and allow them through the Bayer matrix. The filters also work with DSLRs (APS-C sensor size modified cameras are best, but normal ones will also work). When you have the complete stack of exposures, processing is relatively easy because of the large separation in colour. You can also use these filters as a "super luminance filter" for imaging nebulae with Mono cameras.

A quick overview of the Altair filter family:

QuadBand Filter - combines Sii AND Ha into a red zone, and H-beta + Oiii into a green/blue zone. (Recommended for moderate light pollution and skyglow, used with colour cameras).

TriBand Filter - combines Ha into a red zone, and H-beta + Oiii into a green/blue zone. (Recommended for higher light pollution, used with colour cameras).

DualBand Filter - separates the red Ha and blue Oiii channels even more distinctly with even deeper blocking. (Recommended for severe light pollution such as within built-up areas such as cities. Used with colour cameras).

NarrowBand mono camera filter - these isolate single bands, so you only capture one wavelength per filter such as Oiii or Ha or Sii, and they are mostly used with mono B&W astronomy cameras. Separate sets of exposures are required with each filter.

Great 4 years with astrophotography and finally some results, neighbors security lights doesn't affect my job. I'm so happy- someone decided to create filter like this one (05/02/2023) Yahoo - Dunfermline
