Comet 12P/Pons-Brooks

Waves it good but in the twilight with my 15x70 yesterday. Peter -

Comet 12P/Pons-Brooks
PeterW replied to andrew63's topic in Observing - Widefield, Special Events and Comets
Probably my last attempt to see it before it rounds the sun, thin cloud moving through, not sure which direction. Pons brooks is just below right of hamal, quite easy in my 10x50, diffuse spot, but no obvious tail. Glad to have seen. Peter -
I’ll be treasuring the 2024 calendar for a long time, always got it, such great shots. Peter

I’ve seen a lot of nebula images that show essentially nothing, as Ed noted, but it’s there in the data, it just needs better processing to do it justice. If they could add some extra processing levers to allow more to be pulled out then I might drop off the fence, but I can’t be bothered if I have to download and run the data through extra software. For newbies who want to see something it’s a game changer… most astro objects through a similarly priced store scope (apart from the moon, maybe the planets and maybe a few asterisms) will be much worse, especially when you factor in the issue with trying to find stuff! How many cheap scopes linger in lofts and cupboards as they could find stuff and it didn’t look like on the box…. Peter

If the onboard processing was better so you could show nebulae better and mosaic mode was added then it would be almost perfect. Sure a cooled camera on an apo with a really solid EQ mount will beat it…. Field of view you can’t win on…. Good for big nebulae or able to shoot planets and galaxies… half your buyers will hate you. I think the balance is great, but we still need mosaic! you can always wait, a bigger and more costly one will probably arrive, will it be better, will it have different compromises?? Peter

Just seen it in my elderly 15x70 from suburbia, will try to see it as often as I can till it disappears into the southern hemisphere. Peter

The Veil and a 'glowing' North America Nebula
PeterW replied to Ships and Stars's topic in Observing - with Binoculars
If you want hydrogen nebulae then a narrowband Hbeta can deliver, otherwise a narrow oiii can be good. There are some good CN threads: eg https://www.cloudynights.com/topic/722322-pushing-the-filter-envelope-observing-galactic-nebulae-with-handheld-binoculars-under-suburban-skies/ c.hay has done a lot of testing. peter -
Using the full 7mm pupil can begin to show worse stars as your eye lens has worse figure for larger pupil diameters. I’d get a trigger grip and monopod like this… https://binocularsky.com/binoc_mount.php stabilise the 15x70, to improve the view. As others suggest a lighter 8x would be useful, could also be carried around and used in the daytime. peter

I’ve always been a right eye observer, but when the exit pupil gets small, the floaters start to get annoying. Well tonight I decided to get the other eye have a go, and it seems suffers less from floaters. Previously I’d found it harder to use as it’s my non-dominant eye. Quick session as there were clouds about and so I didn’t get the maps out. Saw a fine shadow down the southern edge of the alpine valley and a couple of the small craters along catena Davey with the 127Mak, which seems good, so maybe left eye for the moon from now on! Peter

AstroFest 2024 - 2nd 3rd February - Anyone going?
PeterW replied to whooshbang's topic in The Astro Lounge
“We come from the dark side”, no-one suspected anything… just a few blokes staring at a wall looking though “eyepieces”. Very useful “planning session” too. Peter -
What size scope do you need to benefit from it? Peter

The dark sky reserve will be posting annual updates to their SQM survey and will list multiple good sites in the dark sky area. Local groups will know more and if the council is active in reducing the light pollution, sounds like a good plan to move, though you have to watch out for neighbours with crazy LED flood fittings that can cause issues. peter
