Hi Arne,

Very good. Can the ASI 178MM be binned ?

Hi,

Looks very good.

Hi, Not a nice sky as yesterday but also not that bad as for not doing any imaging. There are some pores in the Soutwestern quadrant at about ~ -32° and ~ +52°coming from the very bright plague visible in H-alpha, I guess it is AR 12806 ? Also some shy remnant pore from the spot AR 12807 at ~ -19° a...

Hi guys, Question, I am trying to understand how to polar line my solarnax iii. Do I really need to align true north or can I just use magnetic north? I want to start doing photography and videos of the sun. Jason You have to align to true north pole when in North and true South when Down Under. I ...

I hope you got compensated for developing the floating worm system the G11 uses?

You made my day

Not even a Thank You. It ook him I think about 5 years or even maybe more to convince himself about this improvement ... and then presented it as his Holy Grail

Rainer, That's a thought. If I could trust them not to be stolen. The Losmandy AZ8 alt-az is very sturdy. It's funny how you mentioned it's the only thing they can build is the tripod. I have some jerkiness in the altitude slow motion control in the mount that can be annoying. I bought the mount fr...

Rainer, It must be really nice not having to set everything up every time and have to take it all in again. It gives you more productive time to image! James Hi James, There are specialized telescope overs available on the market and if you are brave enough you can leave you equipment outside all t...

Hi Maurits,

Very good.

Very beautiful relief in your solar disk Rainer! Thanks for posting these photos. If you had only the WL image with no sunspots, orienting/tilting correctly the sun would not be possible I suppose, or am I wrong? Best wishes, Alexandros Hi Alesandros, Yes, I always know how the Sun is oriented beca...

Hi, Pristine blue sky and according to that much better results as two days before :mrgreen: As fast as the new spots AR 12806 and AR 12807 arose as fast as they went away. Just some tiny pores left from AR 12807. Nice huge brigde porminence on the Southeastern limb as well as something lurking in t...

Hi,

Very well done and you were lucky

Hi Simon,

Excellent

Yes, what a lady :hamster: Pity they don't have any of her sketches to view Alexandra It would be nice if her entire sketch database could be found somewhere. I have numerous white light observations compiled in the 1980s, early 1990s that I could match up against them. Hi James, I made some homewo...

Hi Jochen,

Excellent

Yes, what a lady :hamster: Pity they don't have any of her sketches to view Alexandra Hi, Look here at this link and scroll slowly doen and at about 2/3 of the article there is an animation of some sketches from her. https://www.pbs.org/newshour/science/japanese-hidden-figure-enlightened-world-suns...

Thank you, Rainer. The objective is described as "24mm equivalent", F/2.8 with a 84 degree FOV. A 48 Mp chip.

Franco

WOW and thanks

A cyan tint? That was just me and my monitor not your data. Colors would have been better if I could have used the aligned image set, no PixInsight here. Once the RGB images were combined and auto color corrected in Nebulosity, the tif file was opened in PhotoLine (a Photoshop alternative). This is...

Interesting, Rainer. Looks like she produced lots of good data over her lifetime.

Stu.

Yes. quite a few I would say with 10,000 sketches what I read somewhere

I did not know where to put this. Moderator please move if it is in the wrong topic. Thanks

Hi,

Having got the info from a fellow astronomer about this Japanese Woman who was a great Sun sketcher in her life.

Rainer, I am using SharpCap for acquisition. I can't say anything against you not using color. Your images are very detailed in monochrome. You are also very good in stitching your mosaics together. I will have to learn that since I cannot get full discs in the SMII90. James I also use SharpCap for...

Thanks for the advise Rainer. I do think at times I try to do too much at once. I never see you do your images in color. I am sure you have your reasons for that. One thing is for sure, yours are always sharp and detailed. I haven't used the gain. I leave it at it's lowest setting. I think someone ...

Hi Franco,

Looks great. I am astonished about how well that lens is corrected. What is the focal length ?

Thanks a lot Marty and Rainer, It is obvious from your logs that my system can do better, but for the moment cannot locate the problem. I am stacked at about 140FPS on average. Nevertheless, I have observed what is happening, but first please let me list my laptop's components: LENOVO, Win10 Intel(...

... good camera that will create sharp picture shots ... You already got a lot of information but I have to disappoint you in regard to above statement ... Not a single camera on this planet Earth will deliver you sharp pictures ... It is YOU who has to take care that the camera delivers sharp pict...

Hi Frank, Very well done mosaic. Yes it is tedious but Automatic stitching only works if the images have very detailed anchoring details and here we do not have them. What software packages do you have ? I know one software called AutoStitch https://qpdownload.com/autostitch/ You can try it. I work ...
