Very nice, not something you see every day!

Thanks David. It was a bit scary as the secondary moved freely in my hand 😭 the Tak collimating tube and EP really helped.

It makes sense! For example the CCD chip isn’t perpendicular to the camera optical axis ie tilted.

Thanks David. I have read up a bit on it and it says to try to get an image without nebulosity in it, so I'll maybe fire off a few shorter subs later on this evening. This was my second time collimating any sort of scope, and my first time with a fast reflector.

I processed one of last nights images in CCD inspector. It looks even but any comments would be welcome as I don't know what are a good range of values. Thanks Adam.

It’s been a while since used my DSLR with an MPCC but I thought the EOS M48 adapter got you there exactly? All the stars looks a little eggy so your spacing isn’t quite right. What’s the scopes collimation like also?

Collimation ! When I bought the scope it had been collimated by Orion so I never looked at it closely. This evening I stuck the Tak collimating tube and EP into the scope to find the secondary out of alignment. When I went to loosen the three locking bolts to make adjustments they weren’t event threaded up finger tight, just sitting loose. No wonder it wasn’t collimated any more! I fiddled about for a couple of hours and finally got this. Too late to setup tonight for imaging, will try tomorrow.

I'll chip in here. These were taken using a Maplin regulated powersupply, rated 6-8Amps, and I've measured it and it delivers 14v. It is 2 years old.

Beautiful pictures and a beautiful daughter. My oldest girl is six and I know how much fun they are (most of the time 😂)

That is really something else! My favourite transit pic by a long shot.

I like it! Good solution to your problem whilst still looking normal.

Took me a while to realise that it's actually on top of that pipe!

Wow! thats pretty high, even a fan is bound to help?

I would love to have done the whole thing, but I'm just grateful to have seen it at all. This is 9 frames, I think roughly 1 minute between exposures. Baader WL filter paper, ED80, Nikon D800E, layers manually in PS. Thanks for looking Adam

Very nice! I enjoyed this build thread.

Couple more here

Very nice shot. It's now totally totally tramping it down. So my 15 minutes of imaging are over

Lucky enough here! Screen shot of Firecapture! Hopefully others are lucky too. CS Adam

I’m the same Dave. No idea how to use it. I bought Straton for that reason but would like to get Starnett working.

Made a white light filter for my ED80 and have the lunt set up. I did trial run today, and the OTAs are sufficiently aligned. I’ve work booked off from 11:30am and the forecast is looking ok 🙏

I setup my solar kit today and I’m using firecapture. I didn’t know it could do this! Thanks.

My 60mm b1200 lunt focuses ok with 1.6x GPC, can’t comment on the moonlight

No. I’m just making an observation that halving the area of a circle doesn’t half the diameter.

Is it light gathering that is halved? So like comparing 6” with 4.25” rather than 3”?
