 The Antlia IR Pass 685nm filter is an absorptive filter that allows infrared light with wavelengths of more than 685nm to pass through. At these longer wavelengths, the sensitivity of the unaided eye is reduced, so it is not suitable for visual observations. The filter is highly recommended for any planetary photography. At long-wavelength spectral range the atmospheric air turbulence (seeing) has much lower impact on the sharpness. The closer to the infrared band, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing), result in the sharpest and highest contrast image possible.

 

 By combining a luminance image taken with the IR-Pass filter, along with RGB and U-Venus filters, overall image sharpness is significantly enhanced and details of planets in different bands are taken.
The filter is also possible to image the other planets during daylight due to the dark background sky created by the 685nm IR Pass Filter.

 

Similar to IR Pass 685nm, IR Pass 850nm blocks wavelengths below 850nm allows infrared light with wavelengths of more than 850nm to pass through. It is a supplement filter of IR Pass 685nm.

 

 Sizes: 1.25”

What is the point for me after i bought IR685 last year and IR850 this year frown.gif confused1.gif

Maybe the only thing i hope this Antila to produce is IR1000nm at 1.25" size please, the i will be happy, also if they are planning to make Methane [CH4] filter let me know as i will buy one soon, hope they don't produce filters after i buy them already.

you might find from time to time as you shuffle through life that companies offer products you already own, be they 685nm longpass filters, butter, cars or quilted socks.

 

the trick here is to not buy them, unless you want to have more than you already have. its fine. dont feel bad.

 

its possible this post wasnt targeted specifically at you.

 

PS i already own 685 and 850nm longpass filters, and they are extremely useful for planetary and DSO.

Definitely i won't buy them again unless i lose mine or damage them, but i hope if i buy a product then later i found it new in markets by another maker new to the business maybe and better price and maybe equal quality.

 

I mentioned that i am looking for 2 more filters, one is available and the other i couldn't find really, will Antlia listen and brought them or i buy them somewhere before they officially produce them?

 If you already have a filter, you don’t need to repeat the purchase

 We will consider launching CH4 filter later. Since the sensitivity of the sensor to 1000nm is very low, we will not consider launching a filter of >1000nm for the time being.

 There are already filters. Just wait for good weather and gaze, and look forward to more planetary photos.

What do you mean?

Ok, i understand about not having a further IR filter near 1000nm, not a big deal for me, but about CH4, i hope if you can give an approx. release date as i have about 3-4 months to decide buying CH4 filters, or nearly at the beginning of next year, so i hope you will make it around this time before i buy it from somewhere else, and please, don't make it like ZWO because they have one cheap but i look for the other expensive one.

  We expect to launch the CH4 filter in August this year, but we will first test it internally,

Ok, August is only 2 months from now, i still have time, hope it will be same specifications or performance of non ZWO one because the ZWO one i think it is broader if i remember or not a better CH4, and i believe you will make one with very nice price for 1.25", then i will be very interested, send me one and i can test it also because we have very nice seeing condition for planets. 

 

Can't wait, thanks!
