Unistellar eVscope 2 - First Photos

On this page, I present my first photos that I took with with my electronic 4,5" Newton telescope Unistellar eVscope 2.
*) I ordered the eVscope 2 in October 2021; it arrived at the beginning of December, 2021.

Possibly, these are useful for others who want to acquire the eVscope 2 as well...

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 closer look still exhibits triangular stars).

Meanwhile, I was able to test my repaired eVscope 2 and report on my results on pages First Experiences (After Repair - Part 1) and First Experiences (After Repair - Part 2). According to this, the repair resulted in an improvement, but did not completely eliminate the mirror tension. Unistellar therefore offered me to return my eVscope 2 (end of March 2022) and exchange it for a new one. This arrived on April 8, 2022. So I close the pages for my first eVscope 2 sample!

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 present the very first photos I took with my new eVscope 2. When evaluating the quality of the photos, it should be noted that the telescope arrived decollimated after its long journey to me, and that my first collimation attempts went "in circles" or made things worse.

On this page I present the very first photos that I took with my new eVscope 2. When evaluating the image quality, it should be noted that the telescope probably arrived decollimated after its long journey to me. There is evidence that the focus was also off during the first observation session. My first collimation attempts on subsequent evenings seemed to make matters worse.... When evaluating the results, one must also keep in mind that collimation and focusing are not independent, because after each collimation the focusing has to be repeated.

Very First Photos

In the following I present the photos in alphabetical order according to the DSO numbers. While elsewhere I show photos of the initial collimation state and of my failed collimation attempts, I here try, for space reasons, to show the respective best results that I have achieved so far with the eVscope 2. Where available, I also show comparison photos that I took with the original eVscope (with the new image processing since app version 1.3).

Note: I will replace these photos with my very first photos "after the repair" (but only when everything is in order)!

First Conclusions

Basically, from what I have seen so far, I got the impression that the eVscope 2 delivers a similar image quality as the original eVscope, but not as good a quality as seen on the demo photos from Unistellar (which tempted me to order the eVscope 2...).

Update: 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, which was taken with my eVscope 2 after the repair. It looks much better than my similar photo of Alnitak (near the Flame Nebula), but at closer look still exhibits triangular stars):

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! According to this, the repair resulted in an improvement, but did not completely eliminate the mirror tension. Unistellar therefore offered me to return my eVscope 2 (end of March 2022) and exchange it for a new one. This arrived on April 8, 2022. So I close the pages for my first eVscope 2 sample!

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