Re: My ITF is not in the usual place

Best bet is to keep an eye on fleabay and all the usual 2nd hand haunts for a PST objective, sometimes they come up minus the etalon if it has been used for a mod.

The Maier or beloptik ITF could then be used in conjunction with the blocking filter...

Re: Sunday Sunshine - 17th March

Thanks everyone! I was undersampling Valery, I need to look at a more powerful barlow for CaK, I end up stacking barlows at the moment if I want to get up to >f30 which the extra glass really has an adverse effect on light levels. My 2.5x barlow gives me a annoying ghost at 393nm which rules it out....

Re: My ITF is not in the usual place

Yeah, you have an older PST, the ITF coating is on the objective, that's why it has that cloudy red colour.

Sunday Sunshine - 17th March

Weather forecast was for hail and thundery showers for today, however as is with such unstable air streams the day will start off bright and clear before all of a sudden the clouds bubble up with force. I was out setup and observing by 9am. First off I went to the blue end and got some CaK in as I k...

Looks like you had a productive day with lots of nice images. I think my favourite Ha full disk is the one with the SM60 and the TV101.

Re: Fulldisk Sun 14-03-2019

An exceptional disk! Congrats on another orbit ;)

I hope when the cell for my double stack etalon finally arrives I can get a DS system like yours. You are spot on band with lots of contrast. Look at the bright points in the polar northern latitudes, that's cycle 25 just below the surface...

Let us know what they say Alexandra

Are you dealing with FLIR europe i'm guessing? I've been dealing with Clearview Imaging here in the UK and found them very helpful with my PGR questions https://www.clearviewimaging.co.uk/

I don't think the diameter of the 152 fracs dew shield will be much behind that of the 8" scope. Longer screws would work, you could even drill and tap three holes on the dew shield on the frac so the nylon bolts screw securely into place.
