There is a wealth of information and images with different equipment and observing conditions in this forum. Additionally there is a pretty good search function in Astrobin but lately I have been trying to find pictures to compare different setups and it is not that straightforward. Thus, I was thinking if we could start a thread in this forum showcasing best images of certain equipment - and information stored in a one thread. H-alpha, CaK, White light - all data would be welcomed. This forum is probably the best place in the world with the most diverse commercial and DIY solar imaging hardware available and the potential is huge and ranging from like 30 mm to, I don't know, 300 mm (?) OTA's
The idea:
One could find best examples produced by different imaging setups in one thread and see e.g. what kind of details a Quark can pull with 80 mm or 120 mm OTAs or how does a single stack 60 mm Lunt compare to a 60 mm double stack Lunt or against Coronado 90, how does it look like when using Solarscope 100 mm DS and so on.
What I was thinking:
- State your setup
- State the most relevant acquisition details
- State the most relevant postprocessing details
- State the location (as a rough idea of sky conditions can be interpreted from this)
- Post only one to three images per setup showcasing the best of what it can do (details or full disk or proms etc)
--------------------------------------------
As an example, I'll start:
Setup: Baader 90 mm D-ERF, TS 80 mm f/6 fpl-53 triplet, Quark Chromosphere, Daystar reducer @ ~0.75x, tilt adapter, ASI178mm
Acquisition details: 12 bit capture @ 30 fps, 5000 frames, 2 ms, gain 65 in Firecapture, bin2
Postprocessing details: Autostakkert3!, best 5 % of frames stacked, ImPPG, Photoshop
Location: Southern Finland
Other notes: This is the best image I could obtain with this setup (I still own this Quark, but the OTA is sold). Imaged before noon while the Sun was still getting up.
