Hi. Its been 12 days of lockdown here in New Delhi, India. Gave me some quality time to spend on my childhood hobby. After a long time, I pointed my 10" Dob towards the Moon. And surely it does not disappoint. Its always a pleasure observing its surface. Observing it through eyepiece was a hair raising experience as I moved from 25mm (48x) to 6mm with a 2x Barlow (400x). Later I connected my dslr to the scope and took some quick pictures attached below.
Also took a video. Here's a link to my google drive. Please excuse me for the background noise that is there in the video.
MOON SURFACE - Ultra Close up.mp4
Hi, my current telescope is Celestron ExploraScope 70AZ, thinking upgrade to skywatcher heritage 130P(came with 25mm ajd 10mm EP) , if i do, can i use the eyepiece (4mm) and x3 barlow from my old celestron on the 130P?
One more question, i ordered a eyepiece camera Svbony SV105, i wonder what is magnification of this camera and how it work to change magnification.
An image created by the NASA visualisation studio of what a lunar eclipse would look like from the surface of the moon! Pretty cool right? If you want to get a better understanding of what is happening and why, you can checkout this article HERE which goes into the theory behind it all and also shows you what a solar eclipse would look like from the surface of the moon.
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).

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”.
