And a q.... do I have pinched optics?

This was a single sub.. marked it as bad

disappeared after two subs. must be internal reflections when my neighbour's arc lights switched on when i went to my garden

This is such an improvement. I remember placing the camera and focusing and then turning the camera so it does not turn the focuser under cable tension.

Tested ZWO1600MM with the coronado as the 174M I had for quark was undersampling a lot.. I think I will switch to this cam..

It is a gem, I used it for quite a while. Here's one from the mercury transit of 2016 and a close-up of a prominence

What do you use to increase contrast in the visual observations through your solar scope. I have Coronado single stack 60mm. The double stack unit are under production apparently but have already missed the expected ready by dates. Till they get it out in the market obviously at exorbitant rates, are there any filters I can buy to boost the contrast?

I used this for quite some time. Good views and you can take good photos as well, if you are into it.

it was 63 captures each 1000 frames ~30-33 sec per capture. 30 sec wait between captures Used sharpcap

Forgot to take flats so lots of dust bunnies on surface exposures. So had to satisfy myself with prominence animation only. mp4.mp4

So, I have two dovetails on my scope. One, the factory one and the other from ADM which is not a vixen and is meant to hold Adm accessories. I now use it just for lifting the scope. Took out the scope after 6 months and surprise, I fixed it on the mount using the adm dovetail. And on the third slew, it came off and dropped. I tried to catch it, but couldn't and it fell on the grass. The mirrors however are intact and collimation still as it was before. Maybe just a whiff of good luck.

Sorry for being thick. By alignment do you mean star alignment or something else? Can you give a link to the topic please. I so need to do this. I will have a spare week next month so can finally find time to do this.

Finally done with processing. Followed the steps in Michael's pinned post at the top of this forum. Next try sometime later now.. Solarmax II 60, single stack and Altair Hypercam 174M Mono

Looks interesting... so not strictly as good as dedicated CaK, but still good...
