First Photo Comparison Unistellar eVscope 2 / eVscope

On this page, I present my very first photos that I took with with the first sample of my electronic 4,5" Newton telescope Unistellar eVscope 2 (it arrived at the beginning of December, 2021; ordered in October) and compare these with photos that I took in the past with my original eVscope.

Note: Since I was not satisfied with the results of my new eVscope 2, Unistellar offered to check and possibly repair my eVscope 2. So, I sent it to Unistellar on February 14, 2022 and received information on February 18 that my eVscope 2 had been repaired and will be returned to me. When asked, I was told that there was a problem with the primary mirror, which was slightly under tension and therefore produced blurry images. As proof of the repair, I received a photo of Alnilam. It looks much better than my similar photo of Alnitak (near the Flame Nebula), but at a closer look it still exhibits triangular stars.

I had my first sample of the Unistellar eVscope 2 exchanged for a new one in March/April 2022. So please note that my eVscope 2 photos on this page do not reflect the true performance of the eVscope 2!

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

Introduction

Photos: My eVscope 2 (December 3, 2021)

On this page I compare the very first photos that I took with my new eVscope 2 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.

I may also compare the images pixel-wise one day...

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).

First Conclusions

Since I was not satisfied with the results of my new eVscope 2, Unistellar offered to check and possibly repair my eVscope 2. So, I sent it to Unistellar on February 14, 2022 and received information on February 18 that my eVscope 2 had been repaired and will be returned to me. When asked, I was told that there was a problem with the primary mirror, which was slightly under tension and therefore produced blurry images. As proof of the repair, I received a photo of Alnilam. It looks much better than my similar photo of Alnitak (near the Flame Nebula), but at closer look still exhibits triangular stars):

Photo of Alnilam after repair (taken by me, square format with overlay), unprocessed - I marked some triangular stars, Mar 20, 2022		Photo of Alnilam after repair (taken by me, rectangular format), unprocessed - I marked some triangular stars, Mar 20, 2022

In March 2022, I was able to take first photos with my repaired eVscope 2. Read pages First Experiences (After Repair - Part 1) and First Experiences (After Repair - Part 2) for more information!

So please note that my eVscope 2 photos on this page do not reflect the true performance of the eVscope 2!
