7.9.20

7.09.20 Morning Moon at 35°.

*

Monday 7th Sept. Out in the dome early to capture the Moon and [hopefully] Mars. 

The usual, struggle to find the focus using stacked 2" spacers. I don't do white light often enough to remember the correct arrangement. Nor do I have a focuser. So it's trombone time for the stacked extenders.

According to ASCOM[AWR] Goto, Mars doesn't exist. At least, not in the field of view after syncing on the moon I don't have a finder either. Don't need one on the sun for H-a.


Trembling of the Moon's image on the monitor. The result was too sharpened and noisy after opening and saving with default settings in ImPPG. Not particularly proud of these. Though a craterlet, or two, are just visible in Plato. x2 GPC.[Image left was pushed much harder and it shows]

I'm just not set up for serious lunar imaging at the moment. The 6" f/10 still has all the solar H-a filters fitted. The monochrome ASI174 camera doesn't care if the image is dark red. It may even help with the chromatic aberration. 

 

The 7" f/12 is a much more serious instrument for lunar imaging. While my 10" f/8 Newtonian lash-up left the 7" for dead on lunar detail. Not even collimated and I could easily see lots of craterlets in Plato. I should have persisted and finished the 10" but it was huge and heavy I became obsessed more interested in Solar H-a.

These images are awful compared with the best I have achieved with my bumbling amateurishness before now! You get out what you put in. Garbage in. Garbage out!


 
Moving onto the sun. There were no particular features on Gong-Ha. I captured the NW quadrant with some filaments and surface roughness. The "simmering" seeing is not helpful.
