On this page, I present my early photos that I took with with the third sample (taken up to November 24, 2022) of my electronic 4,5" Newton telescope Unistellar eVscope 2 (it arrived at the beginning of August 22, 2022) and compare these with photos that I took in the past with my original eVscope.

Note: In December 2023, I sold my eVscope 2. For this reason, I will not report any further experiences with this telescope here.

Note: See page Overview of the Unistellar Pages for just that!

Introduction

Photos: My third sample of the eVscope 2 (August 22, 2022)

On this page I compare the first photos that I took with my third sample of the eVscope 2 (up to November 24, 2022) with photos that I took with the original eVscope in the past. Where possible, I selected eVscope photos with the new image processing (since app version 1.3). The photos are scaled down to a width of 1280 pixels for both eVscopes. So, while the eVscope 2 photos offer more pixels, this is not exploited here, and the sky objects look a bit smaller for the eVscope 2 due to its larger field of view.

In this comparison, I present only one photo of each sky object and tried to select the best samples that I got so far. Typically, I present photos that I processed slightly (in Adobe Photoshop Elements).

Early eVscope 2 Photos Compared with eVscope Photos

The eVscope 2 photos were taken during the first observation sessions with my third sample of the eVscope 2 (up to November 24, 2022). In the following, I present the photos in alphabetical order according to the DSO numbers.

First Conclusions

A "real" comparison of the new eVscope 2 with the original eVscope is unfortunately not possible for me, because for this I would have to own both telescopes and point them at the respective celestial objects under comparable conditions (sky conditions, dwell time in Enhanced Vision mode).

In addition, the image processing has also changed a lot over the time I owned the original eVscope: the photos look sharper from app version 1.3 on, but also have slightly different colors and more contrast. Because of the contrast increase, the bright cores of globular star clusters unfortunately wash out more than before. Thus, these photos probably essentially show the difference in the image detail taken by the two telescopes: Objects appear smaller with the eVscope 2. However, if the photos are not displayed at the same size, but based on the pixel counts, objects actually become a bit larger with the eVscope 2 than with the original eVscope (see page Photo Comparison Vaonis Vespera versus Unistellar eVscope (2) - Part 2).

Note: In December 2023, I sold my eVscope 2. For this reason, I will not report any further experiences with this telescope here.
