NGC7000 | Cristoph Kaltseis
1+1=3 / 1st Light and something new – My Picasso | Cristoph Kaltseis

It is with great pride and pleasure to announce European Astronomy Picture of the Day’s new team leader: Cristoph Kaltseis!

Cristoph Kaltseis from Austria was part of the first EAPOD team back in 2016 and is one of the founders of the Central European DeepSky Imaging Conference (www.cedic.at), which is held every two years in Linz since 2009.

Since capturing his first astronomy pictures in 2014, he has quickly established himself as one of Europe’s most acclaimed imagers. In less than five years, he has received four APODs and two EAPODs with Celestron equipment ranging from an 8” Newtonian reflector to a 14” EdgeHD. Nowadays Cristoph enjoys wide field imaging with the 11” Rowe-Ackermann Schmidt Astrograph (RASA).

APF-R

In addition to his various projects, Christoph has developed an innovative image sharpening process called APF-R (Absolute Point of Focus). The procedure is not always the same, but is adapted to the combination of lens and camera. Therefore, a flexible method was necessary to achieve the desired results.

Recently it was made known that the very Hubble Space Telescope team has been using his method for over 2 years, nothing short of the ultimate recognition of APF-R’s effectiveness.

I gave APF-R a go on a HST mosaic and it works around 30% better fine tuned than our other techniques to sharpen mid-tone to shadows, which might not sounds too much but in contrary is a big leap.

Adobe Photoshop

APF-R has also been recognized by Adobe which lead to the Photoshop plugin being available through their app marketplace Adobe Exchange.

EAPOD

EAPODs primary mission is to popularise and increase the exposure of astronomy and science in general by showcasing astronomy-related pictures made by European astrophotographers and scientific institutions.

Selection of EAPODs is carefully carried out by a select group of established European astrophotographers and astronomers (of whom we will post more information soon) and it is Cristoph who will direct this operation from now on.

Vision

The amazing pictures EAPOD features every day already do a great job of increasing interest in astronomy/astrophotography, but it doesn’t end there if it’s up to Cristoph. He has a lot more ideas to involve the general public and thus increasing interest in the wonderful and important aspects that go hand in hand with discovering the cosmos.

We wish Cristoph all the best in his new role and we look forward to everything he will contribute to this amazing community!

This image shows NGC 7000 + IC 5070
Last year I made the 1st Light of the QHY600 M - EB Bin 1x1 / RASA 11 f2.2 + Baader UNB f2 H-Alpha (3,5nm) OIII (4nm) with NGC7000. 

Very short exposure times - because not enough time (in spring) for NGC7000, that it was not too low above the horizon and with some height already the twilight was noticeable. 

Additionally with the OIII data the weather was in the change - the next clouds and rain rolled in. So it was just a bi-color image 1+1 for for 3 colors!

But and with 2021 I made first steps - and I use StarNet to highlight the structures of the image, which are not so clearly visible with the stars.  (Not removing and reinserting the stars into the origin image (making stars more beautiful) - that's no way). 

Like last year and now a bit more fascinated - the NGC7000 as Bi-Color image. 

Enjoy this deep sky art work by nature 😊
