Fantastic as always

[dry meteor]

holy my pc would die from so many images

[edgy gyro]

I'm sure the processing could be improved

[edgy gyro]

took the best part of 5 hours to stack each set.

[primal kraken]

ive never clicked on a pic faster, i knew it was gonna be a banger as always, great shot

[dim girder]

OMG HOLY

[primal kraken]

although yeah i feel like processing can be improved

[undone phoenix]

As always, amazing image!

[wanton sorrel]

Love it when Tom drops Deep Space pics

[primal kraken]

@edgy gyro sry for the tag but we NEED to see an orion core by you

please do it when u can

[dim girder]

Frr

Also do it with a barlow or smt and do extreme lucky imaging at the terapzium

Like moon resolution

[quick iris]

barlow is likely unnecessary lol

[dim girder]

Well if you are doing planetary level of lucky imaging than i would say that it would help

I sometimes shoot m42 at 10ms expotures

[quick iris]

at what f ratio?

also the fov with Tom's 5x barlow (iirc its 5x) would probably be ridiculous... He'd be at like 10m fl.

[dim girder]

F5.9

[quick iris]

a 2x might be fine

[dim girder]

Thats what im saying

[quick iris]

getting more of m42 would be nice tho

[dim girder]

Would bearly fit the 5 stars pf the terapizum

[quick iris]

while probably not getting much less resolution

[dim girder]

I actually got the 6th star with my 3x barlow that I couldnt get without

[quick iris]

what fl without the barlow?

[dim girder]

1200

3600 with

Tiny censor tho

[quick iris]

That's all seeing limited I can guarantee... I'm at 780mm and nearly resolved the 6th star. Seeing got me as well.

The Barlow is just making you even more oversampled.

Your seeing was likely a bit better the night you put the barlow on. I'd bet.

[dim girder]

Ye orion neb is never higher than 15°

[deft badger]

No need for that f/ ratio. Not really a good idea to go over f/10 for deep sky li.

[edgy gyro]

Yeah, no point. M42 is already too low here at 30 degrees. I'd be massively seeing limited so extra sampling won't help.

0.22"/px already

[dim girder]

Yeah .22 is great

Im at .22 with barloe

[dim girder]

@edgy gyro this is .22

Horrible data tho

[boreal walrus]

I could see like 7+ visually

Shouldn't be too hard
