Question Regarding Seeing Conditions & Time of Day

Hi Everyone: This year was a bust for me regarding solar imaging. I moved twice in 3 months, for reasons ranging from flooding in my apartment to an unhinged neighbor. I decided to buy a house rather than continue renting. There were more considerations than just astronomy that went into my decision...

The filaments are quite differentiated, and the granulation is superbly rendered.

Re: My site has been a washout... global warming?

Really Lou? Well, that is a revelation. I can understand why the cost is so prohibitive for both, given the meticulous manufacturing process required! I might have a couple of questions for you regarding solar imaging with the 9.25. Perhaps on private message?

Re: My site has been a washout... global warming?

Lou, my ERF is from AiryLab. They had a run recently. I am sure they are of excellent quality, but they don't come at all cheap. I think he has one left for the 9.25. I am sure the Daystar one was more reasonably priced, and I would be very curious to find out how the two perform! Yes, good seeing i...

Re: A subjective test of the Daystar 250mm ERF

Amazing detail Lou! I didn't know that Daystar manufacturers such large ERFs. I don't see it on their site. Was it custom made? Is it off axis?

My site has been a washout... global warming?

From Montreal... record rainfall for spring and the summer is just a continuation. I just spent an extended time in India this spring, but apparently did not miss anything weather-wise. I am having my Daystar quantum refurbished, and hopefully will get it back next week. In the meantime, I have a Ba...

Herschel Wedge With an SCT

Hi Everyone:

I was wondering whether I can use a Baader or AP Herschel Wedge with a 9.25 SCT and a full front-mounted ERF? I would like to image solar granulation in WL. Or would a front mounted white light filter be preferable?

Thanks!
