Hi all! I've been out of the game for some time now but nice to see familiar faces on SGL! I hope everyone is well and keeping sane and safe!
Lots seems to have changed! New cameras, new software, new lots of things! It's hard to get back up to speed after a few years. My Dad (Mick J) keeps me updated. The general image standard is now so high it seems!
I have a bit of a natural break in work and life things so enjoying some time in Crete with other half's family currently. First time using portable set-up for me and to be honest a lucky capture with the comet in the frame mostly by accident!
Approx 55 minutes total of 30s frames and some 10s frames for M42 core, ISO 400. Modded Canon 450D, Samyang 135mm F2. Skywatcher StarAdventurer.
Similar version of lockdown here so taken from city location and passing cloud but happy to just have some time to enjoy a bit of hobby time! Processing gradients wise was tricky!

Hello all,
I always been fascinated by astronomy and finally purchased a celestron nexstar 8se. Setup went smoothly but I'm a little stuck on the lens. I attached the star diagonal to the telescope and focused in on an object. I was able to see a part of the leaf on the plant in my house and I attached a picture of that. Moving the telescope left and right allowed me to see other things. I then took out the 25mm lens and can see through that when not attached to the telescope. I can see my sandals and feet through the lens and attached a picture of that. I then inserted the 25mm lens into the star diagonal and that's where all hope gets lost. I see white (assuming that's my wall) and yes the cover on the telescope is also off. No matter where I move the telescope. All I see is white. I tried last night in clear skies and pointed towards some clear stars using the skyportal app to align but I didnt see anything except pitch black through the lens. I also played with the focus but nothing. Am I doing something wrong, I would think the 25mm wouldnt be so zoomed in that I cant see anything? Thanks for any help you can provide me. Looking forward to exploring!!

Hey Guys,
I run a Youtube Channel and as part of that I like to live stream the telescope. But the problem is lack of consistency.
Equipment:
Orion EON 110, Meade 10" SCT
Orion Mount - Exos2-PMC. Meade Mount 'push to' alt az with clockwork drive
APT, SharpCap, PHD2, Stellarium, ASCOM Hub
Focal Lengths Orion 660mm, Guide Scopes 188mm, SCT 2500mm
Powered USB for ZWO cameras (120 and 294)
Here is what happens:
Cameras, sometimes work, sometimes don't. I am not making the mistake of trying to get APT and SharpCap to view the same camera. I used APT for the guide scope and SharpCap for the main tube and the 294. Sometimes APT will take an image, sometimes it will do live view, sometimes both, sometimes neither. It is very distracting to the stream to spend an HOUR turning the computer off and on, plugging, unplugging and replugging the cameras just to get them to image.
When I do get an image it plate solves at the NCP, but if you move away, setting the coordinates to the scope position or the object I am looking at, it doesn't consistently plate solve. Sometimes it does, sometimes not. It is completely irregular and can change within a session.
Not all three plate solving means even work, for blind solve,
ASTAP never seems to work, either in point craft or locally stand alone
PS2 and ASPS work intermittently, as above
I did download all the catalogs and they are in the default directories.
This is very frustrating and I was wondering if anyone else is having this issue or has suggestions.

I continue my reports from observatories I have visited. This one is very special for me, I did my education in astrophysics at this place in the 1990s. My girlfriend and I took the car this weekend and visited Saltsjöbaden for a walk, only 30 km from where we live. We ended the walk up at the Stockholm's Observatory.
Some photos from this beautiful place:

One of the observatories at this photos is the astrograph which I already earlier had written about.
