Thanks Bob. Just wondering how this filter is added to the system? Is the idea to swap out one of the filters in the B1800? From my understanding, the leading part of the blocking filter diagonal has the blue disc to reduce the overall brightness and the trailing part has both the filter we are refe...

Davidm

Welcome Vin! Lovely image.

Davidm

I see what you mean. I can probably get a little 'sidestep' with this. Typically, today was the only cloudy day in months, so I'll have to wait a little to give this a go.

Davidm

Wow! They are really 'punchy' images. Great stuff Eric.

Davidm

Thanks Bob, that's interesting info about the other blocking filter option. I only have the B1800 and a B1200 (which needs a new blue glass disk). If I can sort out the centering of the sweet spot, I think I'd like to try the KG3 option. How would I source one of these? I've emailed Lunt to see if t...

Davidm

Thanks all. Ivan, yes these are with the LS152 and a 4x barlow. Rainer, agreed about the prom image having too much white disc. I often cut this out, but didn't bother for that shot as it was one of those inherently 'blurry' proms, which I tend not to work too hard on. Maybe I'm a 'prom snob'?

Davidm

Top shots there. The full disk really shows the range of activity.

Davidm

Thanks Mark. I suspect I’ve dropped more than that, but will have another look to see if that’s actually the case.

Davidm

Hi Mark. I was wondering what options I might have for collimating the optics. An email to Lunt will be the next step for that, I guess. Never tried it in the 11+ years I've had the scope, so perhaps it's time. I read a review of the DSII for the LS152, which noted that the drop in brightness was le...

Davidm

Good stuff Robert. Fingers crossed for some good weather over there!

Davidm

Good stuff Martin. The spots near the limb look particularly impressive.

Davidm

Hi all, Got inspired to pull out the DSII module for the LS152 with the aim of trying to get it usable for imaging (previous attempts have not been good). I still note that the drop in brightness with the double stack is more significant than I thought it should be but I don't have the experience wi...

Davidm

That's awesome.Wonderful fluid movement!

Davidm

The seeing was reasonably good this morning but not quite as good as it has been, so not quite getting the finest detail. Plenty of areas worth having a look at, though.

Davidm

Yes, some fine white-light shots there.

Davidm

That’s an excellent timelapse! Really shows the plasma movement.

Davidm

Hope someone catches the next one!

Davidm

Oops, fixed. There seems to be a pretty high background level of ‘flareiness’ in this active region.

Davidm

That's a good image for the first attempt with this setup. I have struggled with doublestacking myself and received the advice to try different angles between the units. I didn't see a huge difference, but thought one configuration seemed a bit better than others. I had wondered if having an off-cen...

Davidm

Good one John. Looks very impressive in this image.

Davidm · Re: Full disc 29-01-2022 Well done. Some fascinating detail in there.

Well done. Some fascinating detail in there.

Davidm

Really well done there. You managed to get some sharp images despite the seeing.

Davidm

This active region has grown quite a bit over the last few days and looks good for a decent flare at some point.

Davidm

Great observations James. Hope you are back on your feet again soon and that it isn’t anything serious.

Davidm

Excellent animation! Love the fluid, surging motion.

Davidm

Good stuff James. Yikes, 12 degrees is warmer!?

Davidm

Mid-week day off here in Australia (got to love it) and not too hot, so the viewing was good enough to try to capture some detail in the big proms. Captured with 4x and 3.5x barlows.

Davidm

Looks like you are getting this sorted out well. What scope(s) did you use?

Davidm

Yes, great shots there.

Davidm · Re: 01-24-2022 Todays offerings Fantastic detail Simon!

Fantastic detail Simon!

Davidm

Good stuff Pavel. Lots going on at the moment.

Davidm

Excellent full disks there.

Davidm · Re: Full disc 15-01-2022 Excellent shots!

Excellent shots!

Davidm

Tried a couple of mosaics to encompass the range of activity this morning. Each component image was made using a 4x barlow (3600 mm focal length).

Davidm

Great stuff Pedro!

Davidm

Great stuff Pedro!

Davidm

The main active region is certainly worth a look at the moment as it swings around to face us. Some crackling activity looking like it is building up to something.

Davidm

Great report and nice to see a winter setting as a change from the heat of an Australian summer!

Davidm

Excellent images there!

Davidm

Nice one John. Some interesting active regions coming around.

Davidm

Yes, that looks like the same one. I need to set up an alert myself to make sure I don’t miss these as the sun gets more active.

Davidm · Re: Sol 31-12-21 Ha Nicely done!

Nicely done!

Davidm

Great way to finish off the year!

Davidm

Missed some of the other flares and liftoffs in the last couple of days, but noticed a flare from AR2918 on GONG this afternoon (0800 UT), so scrambled to setup my scope in the last remaining patch of sun. Rotten seeing, with a tree branch wobbling across the view in the wind, but managed to grab a ...

Davidm

Awesome sketch. Looks like a great liftoff.

Davidm

Awesome sketch. Looks like a great liftoff.

Davidm

Good one! Like the ghostly look of the first shot.

Davidm

Managed to beat the heat today and do some imaging after a string of boiling hot days. The seeing was on and off, but good enough for a few shots.
