Re: Today's Proms & Limb Filament, Full Disc, HA | March 13th 2019

Great setup and captures. Our students saw that proms on a C8 fitted with an ARIES D-ERF + PST etalon + x2 barlow + ASI224MC. Previously they had seen the view on the same setup with an ASI 174MM. Here is a single frame image of that prom (I hope you don't mind showing this image on this thread). ht...

Hi Marty, Great shots. Liked the Hi-res surface and proms. You mentioned equipment - C8 Edge HD SCT + Aires 200mm Tri-Band D-ERF Quark Chromosphere ASI174MM + 0.5x Focal Reducer PST Q1. Can you show a photo of the optical train? AIRES D-ERF + C8 + PST etalon + ?? Q2. Where do you put in spacers and ...

Re: AR2734 from Singapore

Hi Alfred: what model number is your Jason Rotary Power telescope ? I looked online but could only find a 500 DSM model and a 540 model. Thank you, Franco Hi Franco, I bought it from a friend in the US. It is the F1000mm model. I also can't find in on the web. https://4.bp.blogspot.com/-7L8pl9lfCac...

Nice CaK Alfred, what setup did you use? Hi Mark, It was taken with a 60mm Jason Rotary Power Astronomical Telescope 1000mm FL with a 6mm Baader Planetarium B-CCD ERD mounted inside the telescope followed by a 1.25" 2.4 angstrom CAK filter, x2 barlow and a ASI 174mm camera. https://1.bp.blogspot.co...

Thanks Pepe. I am still working on the etalon tilt, focusing and post processing. This setup is capable of better images.

Lunar New Year Sun from Singapore (6 Feb 19) - New Image added

We had good weather on Lunar New Year holiday (5 and 6 Feb 19) here in Singapore. There were just too many festive matters to attend to on the first day. I managed to do some imaging on the second day of the holiday. In this period of the solar minima there was no fireworks. A lonely plage was visib...
