Not posted some images since my introduction in the welcome section. With the dark nights finally back here in Scotland I thought Id share some of the DSOs I managed to capture back in Feb-April just before the light nights rolled in at the start of May.
These were all stacked and edited in PixInsight.
1. The Running Man and Orion Nebula - less than an hour of integration time (SA pro + fuji 55-200mm lens).
2. Bodes and Cigar Galaxy - Less than an hour of integration time ( SA pro + SW 72 ED telescope).
3. Flame, Horsehead, Running Man and Orion Nebula - Less than an hour of integration time (SA pro + fuji 55-200mm lens).
4. Pinwheel Galaxy - 35 mins integration time (SA pro + SW 72 ED telescope).
5 Whirlpool Galaxy - 21 mins integration time (SA pro + SW 72 ED telescope).
6. Andromeda Galaxy - 1.5 minutes integration time (Move Shoot Move + fuji 55-200mm lens).
M65, M66 and NGC 3628 - The Leo Triplet. Photographed on May 14. Skywatcher 150P with a Nikon D3200 at prime focus. EQ3-2 mount with RA motor drive (no guiding).
19 subs at ISO 800 - 30s each. Aligned and stacked in Deep Sky Stacker to give resulting 4min 30s exposure. Processed in Startools to crop, bin, stretch and colour balance.
This was my second time around to process this image - starting to get the hang of Startools now.
Scope: 20” f3.6 Lukehurst Dob with Paracorr (fl = 2089mm & f4.1).
Night Vision: PVS-14 with Photonis 4g INTENS.
Eyepiece: Plossl 55mm (f2 x38).
In spring 2019 I created a Sky Safari observing list of 214 highest brightness galaxies in the night sky above.
I have observed 134 of the 214 (the others have not been well placed over my garden when I have been outside).
In my first pass through these 134 galaxies, they were graded 0-3 (where 3 means "clear spiral arms" and 0 means "nothing to see here!")
I have now completed a second pass through the grade 2 and grade 3 galaxies. This has resulted in some movement between bands based on my now greater experience and having a better idea of what I expect to see.
My latest graded lists contain 38 grade 3 galaxies and 30 grade 2 galaxies (when combined this gives a list of the best galaxies to view when using military night vision technology combined with a low power eyepiece (using the TeleVue PVS-14 adapter).
[Note that lower power eyepieces give the best spiral arm results as they “increase the effective focal ratio” of the telescope/night vision system which really helps increase the detail seen at the eyepiece.]
As we are still in galaxy season 2020, now seemed a good time to re-publish my findings so others have the opportunity to observe some of these fantastic galaxies before they become “unavailable” for another 10 months…
Grade 3 galaxies (the best of the best).
M51 M61 M64 M65 M66 M81 M90 M91 M94 M95 M96 M99 M100 M101 M106 M109 NGC891 NGC2403 NGC2903 NGC3184 NGC3628 NGC3631 NGC3726 NGC3893 NGC3953 NGC4051 NGC4216 NGC4274 NGC4449 NGC4559 NGC4565 NGC4618 NGC4725 NGC5248 NGC5371 NGC5746 NGC5907 NGC6946
Grade 2 galaxies (good but the arms are not quite there…)
M82 M88 M98 M104 NGC2537 NGC2768 NGC3294 NGC3344 NGC3373 NGC3596 NGC3646 NGC3675 NGC3718 NGC3729 NGC3813 NGC3938 NGC4013 NGC4214 NGC4293 NGC4389 NGC4490 NGC4517 NGC4535 NGC4625 NGC4762 NGC5005 NGC5364 NGC5383 NGC5775 NGC6015 Hopefully someone will find this useful information, next time they plan a galaxy observing session...
Note that my dobsonian uses an Astrodevices Nexus unit which I control using Sky Safari. Here are my exported observing lists (which you can import into your Sky Safari app should you wish to do so?)

Grade 2 Galaxies.skylist
1. email them to your phone/ipad,
2. read the email on your mobile device and after clicking on the attachment, you should be offered the chance to “send to Sky Safari” by your email app…
3.Sky Safari will open and give a message “Observing List Created”.
