Re: January 9 2021 Observations

Thanks for the report James, it looks like the sun has been throwing off filaments yesterday. Looks like i'm going to have cloud again today, was clear overnight and there was a frost at dawn, but the sky is completely overcast now. You just can't win the battle against the clouds. You haven't boug...

Re: Delivery of clouds and WL wedge (h-alpha inbound)

I will be testing it thoroughly. I have a QHY5III178M camera which is normally used for guiding. The 1/1.8-inch sensor is smaller than an IMX174 and is 2.4 micron x 3072 x 2048 e.g. about 7.2mm x 4.9mm. That might be an issue for checking for poor field illumination? I also have colour camera (also...

Re: How effective is a 0.5x Reducer with a Quark?

My advice Simon, evaluate the Quark using the mono camera with 2x2 binning. On terms of eyepieces, Daystars advice of 25-40mm plossls is the best. Personally I don't like using a 40mm plossl, I find it too much like looking through a drinking straw, I use a 32mm and 25mm the most, I think my prefere...

Re: January 7th - A day of Filaments

Mark, the ASI1600 is in the works to be tried for full disk solar after I finish rationalizing the solar scopes. For me, the full disks are meant as a reference as to where features are and then image in higher resolution where there are features. The ASI290 would do a nice job but need to mosaic t...

Re: Repairing a CaK PST

The CaK PST #1 filter and the K-line is a killer combo. My CaK project this year is finding the best double stack combo. I bought another CaK PST off ebay in the autumn and plan is to strip the #1 filter from it, and then from my existing CaK DS filter find which combination of filters works best. H...
