I have a celestron cgx mount I use for this as well as another scope.davenn said:What sort of mount do you have for it ?

Thanks, I've been happy with it so far.davenn said:nice mount
The other scope is a celestron EdgeHD 800. I use this one for smaller objects like planets and galaxies.davenn said:that now begs the question ... what is the other scope ?

Currently, I don't, but I have been thinking about getting an Ha setup for my 80mm and a white light filter for the 8" from 1000 oaks optical. I've heard many good things about their products. Here are the links below.davenn said:without going back through pages of posts, I can't remember if you have any sort of solar filter
davenn said:The Baader filters are good white light filters and I will still use my one for sunspot imaging

Thanks for the advice. I just started looking at Ha solar filters so I haven't really decided what to go with. The daystar filters look very nice, but you definitely pay a premium on them... $10000 for 0.3Adavenn said:just be aware that at 0.9A you are not likely to see the filaments on the face of the disk ( at minimum only a hint of the very largest ones)
as you can see from their supplied images ... the surface features are very blurred
0.9A is quite a broadband bandwidth. for every 0.1A you drop in bandwidth, the features become sharper and sharper
so dropping from the 0.9A down to the 65 - 0.7A of my Lunt system lots more details appear.
Dropping to the 0.45 - 0.5A, of my Daystar Chromospheric filter, is even better for surface/disk face features

Zeke_D said:I am using a Nikon P900 with a Baader 5.0 filter on a regular camera tripod. Usually shoot at maximum optical, 83x, sports mode for a burst of 7 in 1 second. Greater than a minute between shots, it starts to noticeably blur the final image.
I'll post some images to walk through the process.
See e.g. post #150davenn said:I'm still not totally sure of what I am looking at … detail wise ??
yeah, I had read that before I made the commentStavros Kiri said:
Yes. There is just one image where there is a clear area, to the right of the Sun where 'something is going on' but I think we need some help to make more sense of some of the images in post #152.davenn said:Hi there Zeke_D
welcome and thanks for posting in the thread. It's good to see something a bit different
Even with your walk-through of your processing, I have to admit, I'm still not totally sure of what I am looking at … detail wise ??
Continue to post and keep up the explanationsregards

Nice images as usual, Dave.davenn said:16 June 2018, The Sun in Ha.
Some small prom's and a large but ( for me, ill defined) active region probably mainly due to poor atmospheric conditions

The first and third images seem to have areas of light as if it's a slightly polished sphere, illuminated from one side. The spherical appearance is quite noticeable. How's that happening, I wonder? It's almost as if the Dodge Tool had been used.![]()
Yep. I'm pleased that I spotted your bit of tinkering.davenn said:are you referring to the 2 circled areas ?
Have you tried a flat to see how the sensor, scope , filter is actually performing? But I really think the pictures are so nice that it's hardly worth bothering except for interest.davenn said:I can move the sun across the FOV of the camera sensor and it will go through brighter and darker areas ( can't describe it better than that)
sophiecentaur said:It's hard not to assume that the Sun should be totally uniform at all times. But those images are really good to look at.
. . . . due to the sensor orientation?davenn said:I still see the same effect
sophiecentaur said:. . . . due to the sensor orientation?
sophiecentaur said:You could deal with that with Flats, n'est-ce pas?
If you have any constant variation of sensitivity over any image, a flat would help you. Flats help to give a good even background field and that grey / near black level shows up even small variations but they don't visibly affect the relative brightnesses of stars. AP'ers are obsessed with their quality. I am still too excited at just seeing something new on my images to be too bothered.davenn said:Possibly ? doing " flats " is not something I hear guys doing for solar images
Smashing!davenn said:See the black filament within the AR between the 2 white areas
Very sharp looking. Scary when you think just how big it is compared with Earth. Glad they don't get any nearer to us.davenn said:one prominence image
Keep 'em coming Dave. If you can supply enough fab pictures, it will prevent me from lusting after kit like yours!davenn said:The Sun in Ha, 08 July 2018.
Other than a few filaments, the disk of the Sun is blank.
There are some nice prominences in 2 groups along the right hand (West) limb.
Lunt LS60THa scope and a ZWO ASI1600MM astro camera

Yeah, keep them coming, because I am bored to go outside ...davenn said:The Sun in Ha, 08 July 2018.

Looking forward to that! I will get up there to look at it tomorrow.davenn said:There's a new active region just coming around the east limb
I think it's the old AR2715 returning (weakened) ...davenn said:There's a new active region just coming around the east limb
