Huge Solar Flare on 27 May 2023 Timelapse
Bernd Nies replied to Bernd Nies's topic in Imaging - Solar
It was pure luck. I just wanted to try timelapse and have seen the flare in postprocessing. It just lasted about an hour. If I knew it was coming I would have made a timelapse witth short video sequences per interval to get sharper pictures. 😄 -
970 single 16bit frames (1000 actual ones, but there were some clouds) with 20 seconds interval (circa 5.5 hours). Lunt LS60T + ASI 178MM. CME starts at 0:19 (11:53 - 13:06 UT) Postprocessing with Lightroom for enhancing shadows and contrast, export to 8bit PiPP for aligning the images and LRTimelapse for creating the video. PiPP did a better job in stabilizing than ImPPG.

Phantastic picture! I recently tried them visually with a 300 mm f/4 Dobsonian. IC 410 with the dark clouds was clearly visible with O-III filter but from IC 405 which looks as bright on pictures, nothing could be seen that night. https://www.deepskycorner.ch/obj/ic405.en.php https://www.deepskycorner.ch/obj/ic410.en.php

Also M 101 is easy to find. https://www.deepskycorner.ch/m101/m101.en.php Get a Telrad finder, a star chart and learn the constellations. Finding stuff that way is a much more rewarding experience than any goto mount.

Lunt Blocking Filter - Check yours, you won't regret it!
Bernd Nies replied to alanjgreen's topic in Observing - Solar
I had some polish left from polishing an acryl underwater camera dome port and could get the surfaces clean again. Maybe some low abrasive tooth paste with a low RDA value would do it as well. -
Lunt Blocking Filter - Check yours, you won't regret it!
Bernd Nies replied to alanjgreen's topic in Observing - Solar
Just took my Lunt LS60T with B1200 out of the box and wondered about the low contrast. The front blocking filter is all fogged up. I bought it in 2017. They are currently at pre-order only: https://luntsolarsystems.com/product/blue-glass-for-lunt-blocking-filters/ for USD 8.75 plus USD 160 shipping costs ...

Hello, If you need some observing inspiration for the long, cold winter nights: Here's a collection of over 400 deep-sky objects, with historical and physical background information, photographs, drawings, finder charts and visual descriptions, compiled by a group of Swiss amateur astronomers: https://www.deepskycorner.ch/index.en.php Clear skies!
