It will be all about spacing distances, this will be key. Some pictures of setup will help figure out what is going on.

Yup, I thunk that is the best you will get with that method Rod, good result.

Thanks guys!

The bright point are there, definitely grab some images.

I should go to bed now, I have to be up and observing the sun in 6 hours

I'm on a roll here, a good few days in a row! Today I decided to stack the SM90 with my LS50 etalon for a double stack view to make any cycle 25 bright points easier to see. Glad I did, as the area that was designated S6205 in the southern hemisphere seems to have a couple more smaller bright points...

cool setup and some top tips

Some of them are cycle 25 - the spectroscopes like this delve deeper than telescope/filter setups...

More signs of 25! woohoo!

Polar faculae, very nice!

Thanks Bob, thanks Jack. It's an SM90ii scope Bob, but comes with 'history'; it was commissioned for the BBC 'Sky at Night' TV programme 7 or 8 years ago and according to Coronado from it's serial number was classed as a prototype scope. It had a couple of owners since then and i've been fortunate t...

I think you will get better results with a camera with smaller pixels, the IMX174 sensor is best suited up at around f25 in Ha.

Was pleased to wake up this morning to blue skies, so got out of bed nice and early to get some viewing in before work. Seeing wasn't great so lots of sub frames and lots of runs were key to picking out a best image. First up the full disk with the SM90 and GH3 ICX916M - again lots of people online ...

Thanks everyone! No flats Franco, just as it is off the camera chip.

Power supplies all the way for me Alexandra ;) I've noticed the frame rate of mine drops off quite rapidly when I go from 8 bit to 10 bit (I think I will only be using it in 8 bit). It's also considerably less efficient at Ha than my other Grasshopper, and like said a lot more noisier. Whilst I see ...

Here's S6205 in the southern hemisphere today, easy with the DS90, infact really quite bright! https://live.staticflickr.com/65535/48182327151_dc8319ed48_o.jpg s6205-cycle-25-bw by Mark Townley , on Flickr I wouldn't be surprised to see one of the bright points in the northern hemisphere get an 'S' ...

Give it a go Maurits but I don't think you will get rid of the uneven illumination due to variation in bandpass across that quarks FOV, the variation in bandpass will always give a variation in detail. Doubt you will stitch images together for this reason (to get a full disk). My advice if you're af...

Looks lovely!

These are nice shots Lou!

I'm not sure you can effectively, the full disk flat is a holy grail for solar!

An excellent set of images there Pepe!

Thanks Franco, not really tried the proms, they are on my list though. It is a good scope, very flat. I knew this before I bought it, so when the chance came up to purchase it I knew I had to drop the cash and buy it. It also sits very well with my seeing conditions, i'd rather have a smaller scope ...

The unfocused flat is bigger on the chip than the focused image, so when the flat is applied its affects go beyond the limb of the sun.

Super day indeed Pedro, looks a great place.

It is Pedro.
Todays bright point, visible in all the AIA wavelengths. Solen is telling us it's not the only activity from cycle 25 on view. http://www.solen.info/solar/

Let’s hope it really is the start of the activity uptick.

Thanks, Mark.

Stu.

It is the start of the uptick, it's just the rate of uptick that we want to be more rapid!

Thanks Paul!
