My question is why can massive stars fuse heavier elements than helium contrary to medium sized stars like our sun.

I am just checking this site for the first time in 4 years and I’m rolling on the floor laughing reading my posts from when I was in grade 5. Those were the good times.🥹😆
Downright ludicrous was some of the advice I was giving 😂😂.
I also just realized how friendly everyone here is.

Video of montes Apennines
Digiscoped through my ten inch dobsonian with my Sony RX 100 M5
13th November
Please reply if the video doesn’t work (the moon is supposed to move)

So, recently I've been looking at some moon filters and have been leaning towards the Optolong moon and skyglow filter.
Question 2: What effect does it have on 'skyglow'
Question 3: If it works on he moon I'm assuming it also work on the planets?..
Regards,
Neil

+1 for a tabletop dobsonian

My first capture of Jupiter with the Great Red Spot visible. Digiscoped through an untracked 10 inch dobsonian . Video was aligned with PIPP stacked with Autostakkert! 3, processed with Registax 6 and enhanced with Adobe Photoshop. Still have to work on the processing.

Which Celestron zoom? If you provide a link to it, that would help.

So the celestron zoom isn't a good buy? (I can get it for $46 us/36 euros)

Thanks for the replies but I kind of want to stick to the cheaper end of the zoom eyepieces so the baader zoom is pushing it.

I have owned a few zoom eyepieces - baader, televue and more recently a svbony 10 - 30mm. The first two were excellent but much more expensive than the Svbony. I cannot fault the Svbony which I mainly use on my Ha solar scope. I have never tried the 7-21 version but I guess it should be okay.
What scope are you going to use and what objects. Be aware that the 21mms end will have a narrow FOV.

Been wanting a zoom eyepiece for a long time, and have been looking into the Celestron 8 - 24 millimetre zoom eyepiece and the SVBONY 7- 21 millimetre eyepiece. Any suggestions?

No more problems

G' day Spacecake2. Nice to have a fellow Aussie on here! I also observe with a 10" dob as @Kon mentioned, it's a fantastic scope. Feel free to message me and I will help anyway I can. Clear skies!
Thanks

Not a bad start, 47 Tuc is a target few northerners get to see.
Maybe consider shorter exposures and a stacking program.
Deep Sky Stacker is a free program that will help
Yeah my kit wasn’t really for astrophotography and it was a go to tracker so don’t expect much.

Since you are in Australia, have a look at the Observing Reports section and search for @Epick Crom. He is also based down under and you can read what targets are good visually, although he is using a 10" Dob.
I also have a 10 inch dob :)

That’s so detailed! What scope and camera were you using?

On 11/06/2021 at 14:09, Alan64 said:The 25mm and 9mm that came with your kit are most likely modified-achromats(MA), or Kellners; so-so performance. However, I got this 4mm, and of the same "series" as the aforementioned, with my Celestron 127mm "Bird Jones" kit...
Folks either hate it, or love it. I love it, yea, adore it e'en. It produces a power of 250x with the "Bird". Jupiter and Saturn through both...
Now, I saw far more detail, sharpness, during the live view. When attempting to photograph them, they were moving at a pretty fast clip through the field-of-view, hence those sub-standard shots. But then, I took a snapshot of the Moon, through the the 4mm and the "Bird". I set my camera's shutter to 1/45th of a second. As a result, the image was almost black, but then I brightened it, and was floored...
Even at that sub-second shutter-speed, the Moon was nonetheless galloping across the field. What I saw during the live view, again, was tack-sharpness.
But a reflector has to be collimated spot-on to get results like that, as precisely as the mechanical assemblies of the telescope will allow. But as my "Bird" arrived, that was not possible. I had to take the telescope completely apart to enable it to be collimated precisely, also to improve the contrast.
My "Bird"...
It is an economical alternative to a Celestron C5. Indeed, I call it my "C5".
I also owned a Celestron 127 SLT and I think I got the maximum use out of it before upgrading to a 10 inch dobsonian but I actually preferred Barlow lenses instead of a 4mm.

Oh, if you'd like to give that 4mm a whirl round the sky...

I've ordered two eyepieces from that site. It took a while for each to arrive, but they did.
They carry a lot of nice eyepieces, and on the cheap. The only thing is that it takes a while to get it, a month or more.
I’ve never actually tried an eyepiece with 3mm eye relief but is it actually worth it?

Works fine on my iPad with the ios14.6 update.
I think his version is really old so it wasn’t compatible with the new iOS update.

I had it with different apps before and you just have to update it…
