Some photos to relax with.

Wow that is a great view of the arm of Milky Way. Pretty great Astro work mixing with topside. I want to start doing that . Mount it on top of the OTA for guiding. Don’t have to do too long with dslr.

My first attempt at 2xmag of 50mm lens doing a stacked video file. Then did some minor pp. Not a dedicated solar scope but pretty happy happy with there zoom upgrade. I find looking at a ball of 70%Hydrogen and 30%helium fascinating how it is there.

indeed

for some time I've been wanting to add a solar filter into the 'filter holder' of my Sigma 500mm f8 catadaioptric lens and mount it (for which I already have an adaptor) on my m43 camera (making it a 1000mm equivalent lens.

So far I just haven't bought the film and made the adaptor.

I would wonder if my shutter speeds (preferring to stay below ISO 800) will be sufficient for not needing a driven equitorial mount. Any thoughts?

PS in the past I've done a bit of eclipse work with my FD300f4 lens

Some cropping is evident here with only 600mm effective length. Even f4 was insufficient without a lunar mount as we got to totality

worse when I exposed it to 'see the colours'

motion blur was unacceptable

PPS: I notice full size of those (poor) images is not working so please refer to the original blog post for details if desired

For Solar Filters I highly recommend Baader Planetarium solar film for the aperture of your scope. Guiding is recommended to get sharp shots. You want to use short exposures with moon, planets, and sun. Longer exposures with DSO. I would say equatorial mount is the best for astrophotography but the little Seestar has made a liar out of me and cheating system by doing 10 second exposures and stacking on an Alt/Az mount. You will definitely need shorter shutter speeds to overcome blowout. Been a long time since i have shot on film. Don’t think i could go back.

m43 are not film. The m43 cameras are such as this:

I'm not sure where you got film from apart from its use in the "solar film" that I used for the filter (perhaps the solar filter is not a film?)

thanks for the advice

Just processed a shot of Rosette nebula with a combined over 10 hours of stacked exposures over multiple nights. Amazingly processed on iPad with native IOS software.

Decided above exposure destroyed some depth to shot. Here is a shot with less than 3 hours of data in it. I like it better. Rosette Nebula.

Best attempt so far at Heart Nebula, Only capture right and left atrium and AV node (LOL). Will need to try a mosaic on multiple nights. Or will try with different scope. Reflection nebulas are hard for me to photograph.

iPad can stitch images?? That's can be kinda very useful... Thanks!

Here is a shot of M16, known as the eagle nebula. This is where the famous Hubble shot of the “Pillars of Creation” was done 20 years ago and revisited by the James Webb Telescope recently and NASA made a video of the Pillars. https://apple.news/AekkflzrNQD-JNxUeGAViWg

On another note…Sculpture from the Tate Britain. What does it look like to you?

It looks like a dinosaur playing with a ball and unfortunately, he has elephantiasis of the foot lol

Haven't heard that disease for decades.

Thanks for the reminder

Recent image taken a week ago between cloudy days. Butterfly nebula. Playing with different post processing to get more structure in nebula
