Hi Eric,

That is a great set of FDs and close-ups. I like the proms.

I really like both cropped images, Alfred. So much detail to see, especially the first one. Nicely done.

Phil
Thanks, Phil. The details are good. I will trying out other quarks to compare the results.

Re: 19Jan20 - First Light C11+ARIES D-ERF+Quark (New Images Added)

I like the cropped version better. It endeed a very nice start. I'd make several (2-3) more spacers shorter than this one. Then your setup will be more flexible in choosing of a right scale according to seeing conditions and object of interest nature - prominences, dark filaments, ARs, etc. The fai...

Re: 19Jan20 - First Light with C11+ARIES D-ERF+Quark

I used the same Daystar Quark with a TPO x0.5 reducer fitted to a 15mm spacer. https://1.bp.blogspot.com/--ILJ3Hn1PTk/XiLPzhavuVI/AAAAAAAAo5U/Y3tJZvQZdikQfgnbcfMQe3JZlR-nwDTzACLcBGAsYHQ/s640/IMG_20200118_172702.jpg Flats shows an increased FOV that requires cropping of the image https://1.bp.blogspo...

Well done Alfred :hamster: :bow I think you definitely need better seeing and a more active Sun :) I have my new PST mod to test, I am sure that will take a bit of working out as well :)

Alexandra

Re: 19Jan20 - First Light with C11+ARIES D-ERF+Quark

Hi Alfred, Excellent results. To make them better you need the first is to make several adapters between the reducer and the camera C-mount thread. This will allow you to rise the S/R ratio, to get better sampling, larger FOV and sharper images. The worser the seeing, the longer adapter should be u...

19Jan20 - First Light C11+ARIES D-ERF+Quark (Animated GIF Added)

Even though the Northeast Monsoon brings many clouds daily during this period there are always gaps for solar imaging. This morning I tried out the C11+ARIES D-ERF+Quark combination. Before I go further, I must thank Alexandria for helping me linked up with a fine gentleman to make the holder for th...

Re: Sunday 8th December

Hi Alexandra, Your PST images are very nice. The wintry weather makes them special. Over here, the Monsoon rains reduce chances of imaging to zero in the last 2 weeks. Regarding PST mod, I did mine with some care and I was able to re-assemble the PSTs for the coming Boxing Day annular eclipse. So yo...
