In equatorial mount mode, when the composition is not rotated, the FOV rotates with the target, which is the function of the equatorial mount to eliminate field rotation. What do you mean by the offset angle? Do you mean that in equatorial mount mode, when making a plan, after adding a target, the red frame will rotate, right?

    Very disappointed with the new EQ mode, lots if dropped frames and star streaks even after spending a long time setting my S30 up. I have a 2m square concrete Base that is perfect flat and level, but still did not manage to get more than a few frame before star streak started to appear and then repeated star streaks every few frames, not good.

      Just got a reply, it may be changed later, the user may not have to calibrate in only one orientation.

          Oh, that’s wonderful !

          Thank you so much for having asked further your team, very kind and professional.

          Best Regards,

            Support@Seestar This is a common error in understanding the role of sub-exposure time vs total stacked time when stacking multiple frames.

            For a single exposure which will not be stacked with additional exposures, a longer exposure absolutely increases SNR compared to a shorter exposure.

            However, when stacking images, either live or in post processing, using longer exposures for the sub-frames does not necessarily improve SNR compared to stacking shorter exposure frames so long as the total stacked time is the same. For instance, stacking 60 x 10sec exposures for a total of 600sec will result in the same SNR as stacking 20 x 30sec exposures with the same total of 600sec in the final image so long as the read noise is the minor source of noise in the images. And with today's extremely low read noise cameras such as the one inside the Seestar this is likely the case, especially if the gain is set low. Light pollution shot noise is likely the dominant source of noise for many, if not most users, this is the case. Dark current shot noise will likely be the dominant source of noise for anyone working at a dark site, not read noise since the Seestar uses an uncooled sensor.

            When doing post processing of the collected images longer exposures does have the decided advantage of having fewer frames to run through the post processing software which can greatly speed up the processing time.

                frederic_begin When the arm opens, try to rotate the base of Seestar (not the mount that must point north) until the arm points a clear part of sky and then start the alignment .... It could work (taken from another thread)

                    Is the option not to do live stacking (the Live "switch" under Advanced Features) still there in v2.4? To me is very important. Thanks.

                          Here is an example of Markarians Chain from last night ( image rotated to match the chain image) . As you can see I have it framed one way and the software skews it another way. I have tried it with the Sky Alas in Alt-Az mode and in EQ mode. The map in EQ mode worked better but as you can see it is not correct. The framing seemed to work OK when Seestar S50 is not in EQ mode.

                            Brille The last sentence in my post clearly makes the point about reduced processing time. And, yes, fewer frames means less data to take up storage but I hope that would be clear on its own.

                              I apologize for accidentally deleting the last comment due to my mistake. I'll explain here about the S30 gain of 80.
                              The S30 is fixed on HCG mode and normally has a gain of 200, it is the S50 that has a fixed gain of 80, so if your S30 has a gain of 80 in the fit header file, then something is wrong.

                              starnet59 In Android. if you need to revert , you can reset the SS. You can then delete the app from the Android device and side load the version you want. A side loaded version will not auto update.

                                S50 GAIN of 80, S30 GAIN of 200...I made a mistake in my initial post. Apologies for the confusion caused....

                                Hello Seestar team,

                                I am re-upping my previous comment to see if there are any thoughts on a resolution for the sky atlas in EQ mode and planning functions. Thanks! 😊

                                    21Hk60qO Yes, this is a very reasonable suggestion. I will contact you after confirming the situation with the team.

                                      Since the new version, there is no longer a message indicating that there are not enough stars for stacking.
                                      Is this normal?
                                      Thank you.
