On this page, I describe further experiences (no observations) with my electronic 4,5" Newton telescope Unistellar eVscope (I took part in a Kickstarter campaign in mid-November 2017; it arrived on January 27, 2020). This sixth "experiences" page covers first experiences with the new app version 1.4 (from September 2, 2021 on). This page was also meant to cover first experiences with the new app version 1.5 (from December 13, 2021 on) and app version 1.6 (from May 2, 2021 on). However, I had little or no opportunity to make observations with these two app versions, because I did not have an eVscope available at times. And at the beginning of July 2022, App version 2.0.1 was already released, which seems to have little in common with App version 1.x.

I will report on the app version 2 after I will have an eVscope 2 available again (and enough time for observations).

Note: Since Unistellar replaced app version 1.x described here with app version 2.0 at the beginning of July 2022, this page has become obsolete!

Notes:

 

Introduction

Photos: My eVscope (End of January 2020)

Read First, Please!

My eVscope arrived at my home at the end of January 2020. During the first weeks, it had an app with a version number below 1.0. My experiences with this early app version are reported on page Unistellar eVscope - First Experiences. For links to further experiences, see page Overview of the eVscope Pages.

Note: Those who already start with a newer app version do not need to read the above-mentioned pages.

The following experiences are based on the app version 1.4 and refer initially only to changes compared with the previous state, later also to changes made in the course of this version.

On the one hand, according to Unistellar, some bugs were fixed, on the other hand, some changes were made regarding the user interface. So, no new functionality was added!

In the following, I therefore just describe my experiences with this version (an not new features). For a more detailed version history, see page App Version History.

 

The New App Version (Version 1.4.1 and Newer)

App Version 1.4.1 (September 2, 2021)

The new app version (V 1.4.1) is available in Europe since September 2, 2021, and I downloaded it on the very same day. First of all, the app required me, as did the three previous versions, to update my eVscope, which succeeded right away. The new app version offers, according to the App Store, the following new functions (in my own words):

Obviously, app version 1.4.0 was never published...

Status: There were two updates (see below).

eVscope Experience Improvements

Regarding this aspect, I was not able up to now to find out what this refers to...

Various Bug Fixes

As always, no information on this...

Why A Jump in the Version Number?

Why did Unistellar increase the version number, although no new functionality was added? In general, something like this is unusual.... On the one hand, Unistellar indicated to me that the new version contains "tons of bug fixes", and on the other hand, I assume that this version has been adapted to the new eVscope 2 and therefore contains many changes "under the covers". But this is only a guess! However, the quickly following version 1.4.2 (with the same comments) would in my eyes support this assumption ...

Another assumption might be that version numbers jump, whenever an update of the eVscope software is needed...

App Version 1.4.2 (September 16, 2021)

That is, the same...

App Version 1.4.3 (October 18, 2021)

User Alerts for Enhanced Vision Problem Detection

This item was suggested to Unistellar by me (and perhaps by other eVscope users as well...). In an Unistellar Help Center article is explained, how these alerts look like (see below for more).

 

The New Image Format and the New Image Processing

So the main innovation of this app version is still the quadruple size of the photos in Enhanced Vision mode, especially since I had little opportunity to observe with app version 1.3. When comparing "old" and "new" photos or when looking directly at the new photos, I noticed the following changes, beginning with app version 1.3:

On page Old Versus New Image Processing (since V. 1.3), I try to substantiate these observations with examples. There, I also present a collection of examples for comparing the old image processing with the new one. On this page, I present a few selected examples from this collection for illustration. Please click the previews for the larger versions (1280 x 960 pixels) for an easier comparison!

User Alerts for Enhanced Vision Problem Detection

In the Unistellar Help Center article "Enhanced Vision Stopped or Dropped": What does it mean? is described what the error messages, which are issued during Enhanced Vision mode, mean. I therefore just list the messages that can come up:

Enhanced Vision stopped (aborted):

Enhanced Vision dropped (frames are discarded):

 

Small Bug List

Entering DSO Coordinates Manually

If you enter the coordinates of a DSO manually, the app remembers them and displays them again. It does this even if you turn the smartphone off and call up the manual coordinate input again after a few days. However, then the problem occurs that the GoTo control moves in a completely different direction, that is, it uses wrong coordinates. Only after one has once again entered the identical coordinates by hand, the GoTo works correctly.

I have observed the problem myself, and another eVscope owner has also reported it to me. I have not yet investigated at what point in time the error occurs, that is, whether it only occurs after switching off the smartphone or already after restarting the app.

Problems with the eVscope 2?

>> On December 13, 2021, the new app version 1.5 was released, which seemed to exhibit less errors...

 

Suggestions for Improvement

And as always, I wish that important image data would be saved with the image!

 

First Conclusions on Version 1.4

The new image processing actually seems to bring advantages in the presentation of the sky objects, such as more details and sharpness as well as a darker background; increased contrast and changed colors, however, are a matter of taste and and ambivalent one. Now, I only wish that the graininess of the photos and the amplifier glow can be reduced...

In addition, more messages are issued when there are issues during the Enhanced Vision mode. In the Unistellar Help Center article "Enhanced Vision Stopped or Dropped": What does it mean? is described what the error messages, which are issued during Enhanced Vision mode, mean.

 

The NewApp Versions 1.5 and 1.6

Since app version 2.0 had already been published, before I was able to test app version 1.6, the following is already obsolete...

Version 1.5 (13.12.2021) and Newer

On December 13, 2021 App version 1.5 was published, and I installed it already on the same day. First of all, as with the four previous 1.x versions, the app required me to update my eVscope (2), which succeded. According to the App Store, it offers the following improvements:

State: There were no version 1.5 updates.

eVscope Experience Improvements

Various Bug Fixes

As always, no information on this ...

Why the Jump in the Version Number?

A guess would be that a jump in the version number happens, whenever an update of the eVscope (2) software is necessary.

Version 1.6 (2.5.2022) and Newer

Am May 2, 2022 app version 1.6 was published. I was not able to ,load and test it, because I sent my eVscope 2 on May 4 2022 to Unistellar for repair (on August 22, 2022 a new eVscope 2 returned to me, after version 2.0 already had been published). According to the App Store, the new version offers the following improvements:

State: There were no version 1.6 updates.
