Craig from Nevada: This camera targets a very narrow market segment.

I wonder how deep the market segment is for full-frame astrophotography? How many cameras they need to sell to breakeven and who percentage of the market this represents?

This move makes sense. The DSLR world is changing and this is a niche that might be profitable.

While the 2" Focuser Drawtube might Just Barely fully Illuminate the Full-Frame Chip, the T-Adapter inner-diameter of 35-37mm will definitely NOT. Full-Frame users are burdened with the need to provide non-standard T-Ring Camera Mount solutions (similar to the "True 2" Ultrawide Camera Adapter from Modern Photonics).

rrccad: They aren't the first full frame camera for astrophotography.

there's a ton of full framed based astro cameras based upon the Kodak KAI11002 CCD.

now they are right that it's the first full framed DSLR's with a company based IR filter "tweak" for hApha.

since it's also just a narrow band filter for hAlpha - it's a lot more limited as not everything photographed by a astro camera is based upon hAlpha emissions.

@rrccad: The KAI-11002 Sensor, which is used in the QHY-11, is only 11MP. The D810A offers more MP than that in it's DX Crop Mode. And the QHY11 fails at Sensitivity - only QE 34% in Red and 37% overall.

@rrccad: Totally incorrect - it has a more permissive IR-Cut Filter (starts at 700nm rather than ~630-640nm in most Nikon). It is NOT an Ha Narrowband Filter.

mpgxsvcd: I have been saying it for years that Olympus’s live time and Panasonic’s constant preview functions make them ideal for Astro Photography. Now that Nikon slapped the “Astrophotography” label on a camera everyone is also singing the praises of those functions.

I have no doubt this new Nikon Astro camera will be great. However, let me propose some reasons why something like a modified Olympus E-PL5 is a better choice.

1. The E-PL5 has the excellent Sony sensor for outstanding long exposure high ISO photos.
2. The crop sensor is actually better than full frame because full frame requires a much bigger and more expensive scope to cover the full frame.
3. It has the articulated LCD.
4. Cost – A modified E-PL5(Less than $400 fully modified) is about 1/10 the cost of the 810a and a modified camera is even more sensitive to Ha than this astronomy geared Nikon.

I am not saying this camera is not a good choice. However, there are much less expensive options that can achieve the same results.

@rrccad: Again with the "No Good if No HyperStar"... Do you realize that only 1:1000 AP Imagers go the Fastar route ??
AND, when was the last time that you used your $2700 QHY10 as an AutoGuider ?? That's what $400 AutoGuider Cameras are for...

@Vlad: Where did you get any info that Nikon changed the Red Bayer Filter element to be tuned for Ha 656nm ?? The only detail in the Press Release is the substitution of the IR-Cut Filter for one with a Higher Cutoff so as to allow Full Response at 656nm. Not the same...

@rrccad: So, you have a 10MP Color CCD and a Hyperstar'd SCT. You've spent a few times as much as the D810A in order to cover Widefield AP Imaging with a Speedy Focal Ratio. Your QHY10 has a QE of 50% for Blue and Red - very similar to the D810. Other than where it doesn't have a suitable shape for your Fastar, where do yo REALLY outshine the D810A ??

maverick786us: Why would someone spend 3300$ for just taking stellar photography, when its not meant for normal phorography?

@maverick: All it takes is a simple Custom White Balance to offset the additional Red allowed by the D810A's deeper IR-Cut Filter. Those of us with Modded DSLRs have been doing this for almost a Decade now!!

On ACDSee Ultimate 8 introduces layer-based editing article (66 comments in total)
In reply to:

marc petzold: I used to use ACDsee since 2.x as my default picture viewer on windows, because it was blazing fast, compared to all the others....but unfortunately, i think even the "Ultimate" Edition of ACDsee 8 can't really compete with the now "old" 2012 CS6 Release of Photoshop. I tested a couple days the trial from CC, but it's soo slow & bloated, on my older selfmade Quadcore PC, and i really don't need the new features from CC, also i don't want to have a abo.

I only think - compared to Lightroom 5.x, ACDsee 8 Ultimate is simply way too expensive - 149 $. For instance, there is Corel's Aftershot Pro 2.x, which is way fast, and even the completely FREE RawTherapee, as a good RAW Converter tool...and dozens of others.

" Photoshop CS6 ... is a complete Photoeditor, whereas ACDsee is some kind of RAW Converter with Extras, just like all the others."

I think that you seriously under-estimate ACDSee Ultimate 8 (and the Pro series from 5-8). All of these have a complete IMAGE EDITOR which has Exposure, Lighting, Color, Noise, Sharpening, Geometry, Repair, and Vector tools which support Brushes and Selections and Lasso/Wands. AND now LAYERS!
What core EDITOR Functions are missing that might be needed to qualify ACDSee Ultimate 8 as an EDITOR ?? (An excessive Price??)

On ACD Systems issues ACDSee Pro 6 and ACDSee 15 article (75 comments in total)
In reply to:

smartphoto: I"ve downloaded it yesterday, thought give it a try. So far, so good. Actually I was shocked how good it is, just have a small problem - didn't find a way to transfer edited image directly to Photoshop - instead it opens in Camera Raw, without my edits. Is the only way to save a file? Because now I save Tiff, then open it manually in Photoshop. Other than that, I"m really really impressed, even coming from DPP.

ACDSee (Pro and regular) allows you to define multiple "External Editors" (including whether each can handle multiple files). Then you simply Right-Click (or Tools/Editor menu) any Image file and select to use one of the defined External Editors. I use this functionality to invoke PSE or CS3 or my Pano App or my Astro Image Apps or...

On 10 Photography Accessories for Under $250 article (62 comments in total)

I don't see it fair (or applicable) to include an External HDD (any maker) as a "Photography Accessory", as it is rather a PC Accessory. (Admittedly, no form of non-film photography is free from PC involvement - Downloading, PS'ing, Printing, Sharing.) But, unless the External HDD includes an active USB Master or Card Reader in order to perform Camera or Card-based Image Downloads, the HDD is simply an inert block taking up space in a camera bag while awaiting a Laptop to be powered up.
