You are correct, I used to use a reusable shower cap over the bottom of my dobs, I just ordered an oversized, elastisized one from Amazon for $15 C. Thanx !  PS:  One of these days they will come out with a cover specificly for the smart scopes, no doubt but at a premium price.

Asked ZWO & received prompt answer:

All operations, including stacking, are done in the Seestar S50 itself.

While recording & stacking is in progress the phone may be disconnected.

The app is designed for mobile we havent tested on mac or windows android sub system.

Here 2 images from Arp 278

Both with Evo 8 @ F/5

First with ASI290MM

Second with ASI533MC

I took a look in my past observations and found also those 2 galaxies.

NGC 147

Evo 8 @ F/5

Lodestar X2 mono

7 x 20 s

NGC 185 (and UGC 378)

Evo 8 @ F/5.3

ASI533MM

61 x 15 s

My trials on Arp 28

Evo 8 @ F/5

ASI290MM

ASI533MC-Pro

from a long time ago (august 2017)

NGC 6537

Evo 8 @ F/6.4

ATIK Infinity

3 x 45 s

See here: https://www.cloudynights.com/topic/562325-partial-observation-of-einsteins-cross-gravitationally-lensed-quasar/#entry7632228

Starting February I was also imaging about 30 Hickson objects.

As a comparison here are mine with a ASI290MM at BIN 2 under Bortle 7 with a 6 SE @ F/5

HCG 68   27 x 10 s

HCG 61   21 x 10 s

HCG 57   25 x 10 s

HCG 50 which I imaged March 25 in Bortle 7

6 SE @ f/5

13 x 10 s

Arp 214 from a few days ago.

Evo 8 @ f/5.3

Imaged Arp 104 "The Keenan's System - Bridge" back in 2020.

Evo 8 @ f/5

ASI533MC-Pro

20 x 45 s

In the inverted image the "Bridge" can be 'hardly' seen.

HCG 68

Evo 8 @ f/5

ASI533MC-Pro

10 x 30 s

My latest EAA on Arp 285:

6 SE @ f/5 with ASI290MM

Bortle 7

39 x 8 s

Those are my NGC 2022 images:

Evo 8 @ F/4.9     Lodestar X 2 Mono     2 x 30 s

Evo 8 @ F/4.7    ASI290MM    11 x 8 s   BIN 2

Arp 331

6 SE @ F/5

ASI290MM

Bortle 7

28 x 10 s

Tried to image Arp 190 and managed to see the tidal stream (going down and up to the right).

Indeed comparable to the "Antenna" Galaxies.

Celestron 6 SE

Bortle 7

ASI290MM

80/90 x 10 s

Arp 150

Evolution 8 @ f/4.7

ASI290MM

8 x 20 s

I can't resist either to image NGC 6888 once a year...😀

ASI533MC-Pro

11 x 30 s

I use ASTAP to do that. 

In SharpCap I always store a fits file to import in ASTAP.

excellent

Arp 99 - NGC 7547 + 49 + 50 - HCG 93 - Sp. & Ell. G. in Peg

Evolution 8 @ f/4.7

ZWO ASI290MM

12 x 10 s

I tried it with a ZWO ASI533MC-Pro on Evolution 8 @ f/5.3

12 x 10 s

ARP 220 imaged at June 2019

Evolution 8 @ F/5   ASI290MM   

Full moon (some dew at corrector)

6 x 15 s
