Thank you so much! I'll definitely be looking into dew heaters in the future!
Additional stacking definitely improves how bright faint objects appear, but it has gradually diminishing returns. In my limited experience you're right though.
Longer single frame exposure are definitely better, as long as the overall integration time remains the same.
The problem is my setup is at its limit with a 500mm lens on an APS-C sensor, going above 30 seconds without autoguiding would be incredibly hard!
I also have a 200mm lens that I got up to 120 sec exposures without trailing, but it's definitely a challenge.
Thanks for the feedback!
My 5th time trying to image a seemingly easy target with something being off... This time I must have nudged the lens out of focus slightly and there was some dew forming on the lens that I hadn't noticed. This hobby sure has a steep learning curve!
Still, decided to not throw away the whole attempt and did a quick processing. It's about 45 minutes worth of 30 sec exposures at 500mm f6.3.
Feedback appreciated!
Thank you! I'm currently trying to get decent shots of the easier targets before moving on to harder ones
Spot on! A few clouds, discarded about 20% of my lights but given the overall time of just over 30mins I kept some I maybe shouldn't have.
Also I don't have a dew heater yet so I had some condensation issues.
That is indeed a 12 blade aperture, the lens is a ttartisan 500mm f6.3

Thank you for your kind words!
63 x30 sec tracked, 10 of each calibration frames. Stock Sony A6000, ISO 1600. 500mm f8 ish with a ttartisan lens.
Feedback appreciated!
Those guys sure love banning things. They're gonna lose track of all the things they've banned, unless they hire someone to tally all their bans.
Unless of course there's a ban on that too

The vivo has amazing hardware as a base, Pixel is OK hardware but amazing software. It's a different approach but it does seem to work great
Bald Eagle for national bird, but honorary mention for the red-tailed hawk, which is the sound people mistakenly associate it with
That's where the (Na) comes from. Anything starting with Nit comes from Nitrogen (N)
73x30 sec of the Orion nebula, with a stock Sony a6000 and a ttartisan 500mm f6.3 on a StarAdventurer.
Lens was wide open, which introduced lots of aberrations on the brightest stars. Will try stopping down next time. Also, focus wasn't perfect and I had some dew issues.
No calibration frames, either, I was just testing the lens for the first time.

Inb4 they use that "without due process of law" line to deport people with a judge's nod
Yes, this is on a StarAdventurer tracker, but 500mm is pretty much the limit for it.
The autoguider is basically a small scope with a small camera connected to a computer which runs the software you mentioned and uses the data from the secondary scope to correct the movement of the main scope in real time.
A go-to mount is definitely my next big upgrade as well.
Clear skies!
