On this page I provide some information about my forthcoming electronic 4,5" Newton telescope Unistellar eVscope 2, 112 mm/450 mm (f/4) (ordered on November 9, 2021; delivered on December 3, 2021). After the launches of the original eVscope at the end of 2019 and of the eVscope Equinox (no eyepiece) in spring 2021, Unistellar launched the eVscope 2 in mid-September 2021. This model looks similar to the original eVscope, but offers a new sensor chip (IMX347) and an improved electronic eyepiece (designed by Nikon). In many respects, the eVscope 2 looks like "what the original eVscope should have been"... More on the eVscope 2 on this page and from Unistellar!

Notes:

Note: I received my eVscope 2 at the beginning of December 2021 (I bought it, because I was convinced by the better image quality and the slightly larger field of view). I will therefore sell my eVscope (only within Germany, for self-collectors).

 

Introduction

In September 2021 Unistellar launched the eVscope 2, which offers an improved electronic eyepiece and a new, larger sensor (Sony IMX347). It does not differ much from the original eVscope with respect to its look. It costs including the backpack, with which it is sold as a package, 800 Euros more than the original model without a backpack. The differences between the eVscope models (the original eVscope is no longer availabe) are described here.

Delivery

On Oct 29, 2021, I received an e-mail from Unistellar stating that I would receive a tracking number between Nov 18 and Nov 26, 2021 and an update on Nov 17, 2021. It looked as if the waiting time would be much shorter for the eVscope 2 than for the original eVscope... The update was made on Nov 17, 2021 as promised, however, the date for sending the tracking number was now moved to between Nov 25 and Dec 1, 2021.

On Nov 29, 2021 I received several e-mails at once: first one from Anna, with the message that my eVscope 2 was prepared for shipment last Friday (Nov 26) and that I would receive a tracking number by Wednesday, Dec 1, 2021, at the latest. Then came an e-mail from Unistellar including a link to the tracking and tracing number (addressing my landlord in Erkerode near Braunschweig, to whom I had redirected the package); then Anna also sent me the link. And last, but not least, the French parcel service Chronopost sent me an e-mail on Nov 29 with the tracking number (or more precisely, with two; the second was later used by DPD on the German side). And that was when the mischief started! The address was slightly changed, but worse was that the postal code was completely wrong and belonged to a place near Dresden or Meißen. When I noticed that my jaws dropped! I hurriedly wrote an e-mail to Anna and also on the same day another one to Chronopost. There was no reaction from Chronopost, Anna's arrived the next morning: The data in the Unistellar system was correct! So they must have "slipped" somewhere at the logistics company Kairos Logistique or at Chronopost. She would follow up with the logistics company and get back to me, what she did on the day of delivery (for more, see below).

On Dec 1, 2021, DPD contacted me by e-mail and announced a delivery in 1-2 days. The postal code was still the wrong one! I was also able to do the tracking only with this wrong zip code. However, when I selected test "Choose neighbor" (deliver to neighbor), a map of Erkerode appeared. That was all very strange! Thereupon, I tried to present the case in the DPD contact form. In the follow-up of the tracking, first a parcel center near Frankfurt appeared, later one near Dresden (Kesselsdorf). So my bad premonition that the parcel would end up near Dresden came indeed true! It stayed that way on Dec 2, 2021, except that I received an e-mail from DPD that the delivery of the parcel would be delayed (traffic problems were mentioned as one possible reason), but they would work on delivering it in 1-2 days (i.e., one day later). I also discovered that was I now able to access the tracking with both the wrong and correct zip code! Something must have happened "quietly" (on the day of delivery, I learned that Anna was able to correct the postal code)!

In the night from the second to the third of December 2021, the package seems to have found its way to the parcel center in Salzgitter! Because when I called up the tracking again in the morning of Dec 3, a map with the surroundings of the parcel center in Salzgitter appeared now. And at shortly after 10 o'clock, I received an e-mail from DPD that the package would be delivered that noon (I I overlooked one from Anna...). The time period for delivery was a bit in flux, and the DPD car (reindeer...) hardly approached Erkerode, but eventually it arrived at quarter past 12 (I skipped a planned shopping ride with my bicycle) and was handed over to me.

When I wanted to send an e-mail to Anna at Unistellar shortly afterwards to inform her of the successful delivery, I realized that I had overlooked an e- mail from her that she had sent that morning. It stated that she was able to correct to postal code and that my parcel will be with me soon! So I gladly thanked her for her tremendous help!

 

About the eVscope 2

What is the eVscope?

Since the eVscope 2 is an update and improvement of the original eVscope, I will not repeat the main characteristics of the eVscope family of electronic telescopes here. See page eVscope - Information for more information on this.

Details and technical data can be found at Data for the Unistellar eVscope 2.

Brief History of the eVscope, Who is Behind the eVscope?

For the history of the eVscope and the people behind it, see eVscope - Information.

Why Did I Buy an eVscope 2?

On the one hand, the eVscope was exactly what I would expect from an electronic telescope. On the other hand, it gave me not only pleasure, but also a lot of frustration. That was to be expected with new technology, but my hope was actually that certain initial problems, especially of the app, would be eliminated faster than actually happened. Nevertheless, O was happy to have opted for the eVscope on Kickstarter. That way, it was considerably more affordable than when I had bought it later at a dealer.

The eVscope's "competition" consists of the Vaonis Stellina and Vespera refractors (I ordered the latter, again on Kickstarter on the one hand), and of self-assembled EAA configurations on the other. I have either started (Vespera) or even already explored both of these options (own EAA configurations).

For exploring my own EAA configurations, I bought an Atik Infinity and meanwhile also an ASI224 camera. The latter has the same sensor as the eVscope, so that I can use it to compare how the eVscope compares to self-assembled EAA configurations. In comparison with my own EAA configurations, I noticed the aggressive image processing of the eVscope, looking more like "painting" and causing details to be lost (most noticeable and "worst" in the case of the Orion Nebula M 42). However, with app version 1.3, Unistellar released an image processing that, in addition to upscaling the photos, produces much more detailed photos. Actually, I would have to use it to repeat all my eVscope photos, which would be quite an effort....

The Vaonis telescopes, on the other hand, provide better image quality than the eVscope, but in return you have to wait much longer for the result, at least if you value good image quality. What this means in detail, I will find out after the Vespera has arrived at my place. Overall, the Vaonis telescopes seem to me to offer a very different "observing experience" than the eVscope: you have to be much more patient! When I present the eVscope to others, I notice how their patience runs out after just a few minutes. In that case, a Stellina or Vespera would probably not be appropriate at all.... Thus, the eVscope shines for me with its quick and easy setup and the possibility to access and photograph many targets in one evening. With my own EAA configurations, on the other hand, I never got beyond testing.... I put some hope on the StellarMate astrocomputer, with which I can set up small equipments in 5-10 minutes. But I have not yet been able to gain any experience with its GoTo behavior...

Somewhat surprisingly for me, Unistellar announced the eVscope 2 in September 2021, whose most important innovation for me is a new sensor (IMX 347) with slightly more pixels and a little more field of view - enough to show the moon completely now. At first, the eVscope 2 did not appeal to me much, especially since I found 10% discount for eVscope owners to be quite "stingy". However, after more and more image samples (there are still far too few!) were published, I started to change my opinion. Somehow, the eVscope 2 seemed to me like the telescope the eVscope should have been. And because I am quite convinced of the basic concept of the eVscope, I decided to order the eVscope 2 before the rebate period expired (which was not without problems...) and received it on December 3, 2021 after a "one-day detour" to Dresden.

Published and Sent Photos

Since I do not yet own the eVscope 2 and therefore cannot present any photos of my own, I present photos on this page that Unistellar has published on their Website (eVscope 2 product page) so far, or photos that Unistellar sent me on request. The published photos are reduced in size and partly cropped, the sent ones are, except for the moon, in their original format (the large versions). I do neither know, whether these photos were post-processed, nor how long they were exposed (dwell time in EV or LV mode).
