Hi I was just at the dark sky site it is all clear ,the site I winter maintained by the township . Dave

Hi… I’m in the same “hide/wait and see” group. I agree with Attilla that the waterwater monitoring numbers are not going in the right direction – it’s just about as high as it was back in

Hi Attilla, For those doing planning who might also participate in RASC events, normally there is a joint event between RASC Ottawa and CASM, but nothing is in place yet for that...although they

I have a friend who wants to observe at the Frontenac Dark-Sky preserve (aka 'frontenac platform') tomorrow night. Anyone know if the driveway/parking lot is accessible? I.e no berm of ice/show across

Astronomy Day is May 7. Jim Thompson has asked me if te OAFs are having a public event. He is planning to report on public events in Ottawa for astronomy day (RASC, OAOG). So please post if you

Hi Oscar, I did see your kind offer.? I live about 1 hour from you.? It would be pretty tough to put my young kids to bed and make it out there with my gear.? I'll ping you if I'm going to be out

Hi Greg! Sometime last year I read an article that discussed the down side of having too small a pixel size…of course I can’t remember where I saw it. But I did find a few articles online….I am

Hey Greg, Not sure if it got lost in the thread somewhere, but you’re welcome to try out my AS174mm — I live about 40 minutes west of Ottawa in White Lake, if you’re able to get out here, or I

Hi Chris, Thanks for taking the time to look into this.? ASI does publish QE data in the NIR spectrum up to 1000nm.? My camera is very sensitive in NIR >750nm.. I have used it along with an IR pass

Hi Greg! I just watched a video about the ONAG manufactured by Innovations Foresight...very informative. The item that struck me the most is the need to get a strong IR emitting star and having a

Hi Bob, The ONAG does take up most of my BF.? In fact I'm 2mm over ideal BF on the imaging camera.? What guide camera are you using?? I'm wondering if my camera's high IR sensitivity is causing

Hi Greg, I own a ONAG and it can work very well although it does take a lot of room in the optical train. You can sometimes tell if the guider image is focused by the shape of the stars in the guide

Hi Greg! Sorry I missed that...I was not aware of this system of guiding...will need to get familiar with the technicalities of that equipment! I just don’t see the guide camera being the issue. I

Hi Chris, The galaxy image is from my main camera.? It's been cropped significantly.? It's my first Whirlpool galaxy and I wanted to share it.? I got lazy and didn't remove the stars when

Hi Rick, If you're friend is willing to speak to me I would be very interested in picking his brain on optimizing the ONAG.? I bought it used to guide at high focal lengths.? Many people claim it's

Hi Oscar! I was referring to the Greg's guiding camera. Greg! I am going to ask what may appear to be a dumb question...the image you posted...is this from the primary imaging camera...at this point

Hi Greg: I don't think having larger pixels on your guide camera will improve anything - you will likely still have the same size (in arcsec) guide stars, you just won't be able to resolve them as

I find this thread interesting even though I'm not an astrophotographer. I would have thought that "camera" would be the last entry on the list of suspects causing bloated stars. I would have guessed

Hi Chris, The imaging camera is an ASI2600MC which was paired with an Optolong L-pro filter.? I was taking 1 minute subs and stacked using Pixinsight.? My focus regiment is NINA's auto focus
