Re: Thank you!!! Excitement!!! First light Lunt130MT

Congratulations on your superb instrument and great, first results. :bow

Now all we need is an explanation of how you managed to carry your "table and chair mounting" 2100m up the mountain? ;)

Re: H alpha filter as ERF?

My 50mm protection filters are on a long extension well up inside the main tube. Thereby hoping to avoid the hottest section of the focused beam near the focus. I'd have to withdraw the entire optical train including the PST etalon, fittings and blocking filters. I wonder whether the filters have th...

Re: AR12822 in Ha on May 11

Stunning detail! Your seeing conditions must be incredibly good.
Do you image from within a city or a rural location?
Congratulations on your captures and your skills at processing! :bow

Re: H alpha filter as ERF?

It would be useful to have this sort of temperature gain data for common optical components in a skeleton tube OTA. The [laser guided] remote sensing thermometers need a clear shot to be able to measure surface temperature. Most of us have sealed OTAs where such access is all but impossible. I tried...

Re: Polar alignment during the day

A liquid damped, rectangular "protractor" compass, kept well away from ANY heavy metal. I use a 2m long, square aluminium tube against the flat side of the mounting. Compass resting on the tube. A small, magnetic, digital clinometer on the PA shaft. Or PA housing, if parallel with the shaf...

Re: H alpha filter as ERF?

I have lots of nasty experiences with sub-aperture Baader D-ERFs placed INSIDE the telescope. Note that I image all the hours in the day if the sun is out. That is a lot of heat exposure compared to many hobby imagers. Who can only image when time allows. I am retired so can spend countless hours in...

Re: Height of imaging rig vs “seeing”

Thanks Terry. :bow Your project sounds far more sophisticated than mine. But based on my own experience: Don't build a plywood dome without covering it in GRP from the outset. I spent many hundreds of monetary units on "marine quality" sealants and they all just cracked wide open in use. D...

Re: Height of imaging rig vs “seeing”

Thanks. I built that myself a couple of years ago and must have spent hundred of hours imaging in it.
A larger GRP dome 4.3m [14'] is [hopefully] only a month or two away from completion.
The 10' plywood dome is not sufficiently waterproof. Nor large enough for my 7" f/12 refractor + dewshield.

Re: Height of imaging rig vs “seeing”

I have some experience with my raised observatory in a very rural situation. Fields rise gently to my east with low hedges and a few isolated trees before more distant forest starts at 1000m. I had to go high just to see over the nearest field hedges! Which are trimmed for thickness but not height. ...

Re: ImPPG version 0.6.3

Your ImPPG version is over-sharpened. Leading to uniform and unnatural artefacts.
ImPPG should ideally be used just after your stacking software.

ImPPG is the only software which will save the day in poor seeing conditions.

It was clear and sunny today but AS!3 is hiding its processed files.
So, this is the only image I can share from today's several hours of AVI captures.

14.04.2021 More daubs of multiple spots.

It was sunny early on so I set up for imaging. These were taken through slow moving cloud. Heavy cropping from full frame. Rather over-sharpened. After that it went downhill. More and more cloud. Now the cloud has cleared but the seeing is mushy. Worth a look in white light too. Four dark spots near...

1.03.2021 A couple of snaps.

Unexpected sunshine this afternoon. First imaging session in quite a while.
Seeing middling. In and out of focus and thermal wobbles.
